Jog Frequency – The jog speed setting is used whenever the Jog command is active.
The jog speed setting range is arbitrarily limited to 10 Hz, to provide safety during
manual operation. The acceleration to the jog frequency is instantaneous, but you can
choose from three modes for the best method for stopping the jog operation.

Torque Control Algorithms
The inverter generates the motor output
according to the V/f algorithm selected.
Parameter A044 selects the inverter algorithm
for generating the frequency output, as shown in
the diagram to the right (A244 for 2nd motor).
The factory default is 00 (constant torque).
Review the following description to help you
choose the best torque control algorithm for your
application.
The built-in V/f curves are oriented toward developing constant torque or
variable torque characteristics (see graphs below). You can select either
constant torque or reduced torque V/f control.
Constant and Variable (Reduced) Torque The
graph at right shows the constant torque
characteristic from 0Hz to the base frequency
A003. The voltage remains constant for output
frequencies higher than the base frequency.
The graph above (right) shows the variable (reduced) torque curve, which has a
constant torque characteristic from 0Hz to 10% of the base frequency. This helps to
achieve higher torque at low speed with reduced torque curve at higher speeds.
Sensorless Vector Control You can achieve high torque performance (200% torque at
0.5Hz of output frequency) without motor speed feedback (encoder feedback), which is
so-called sensorless vector control (SLV control).
Free V/F Control The free V/F setting function allows you to set an arbitrary V/F
characteristics by specifying the voltages and frequencies (b100~b113) for the seven
points on the V/F characteristic curve.
The free V/F frequencies 1 to 7 set by this function must always be in the collating
sequence of “1<2<3<4<5<6<7”.
Since all the free V/F frequencies are set to 0Hz as default (factory setting), specify their
arbitrary values (being set with free-setting V/F frequency 7). The inverter does not
operate the free V/F characteristics with the factory setting.

Manual Torque Boost The Constant
and Variable Torque algorithms
feature an adjustable
torque boost
curve. When the motor load has a lot of
inertia or starting friction, you may
need to increase the low frequency
starting torque characteristics by
boosting the voltage above the normal
V/f ratio (shown at right). The function
attempts to compensate for voltage
drop in the motor primary winding in
the low speed range.
The boost is applied from zero to the base frequency. You set the breakpoint of the boost
(point A on the graph) by using parameters A042 and A043. The manual boost is
calculated as an addition to the standard V/f curve.
Be aware that running the motor at a low speed for a long time can cause motor
overheating. This is particularly true when manual torque boost is ON, or if the motor
relies on a built-in fan for cooling.
Voltage gain Using parameter A045 you can
modify the voltage gain of the inverter (see
graph at right). This is specified as a
percentage of the full scale output voltage.
The gain can be set from 20% to 100%. It
should be adjusted in accordance with the
motor specifications. Gain can be changed
even during operation in V/f mode, and while
stopped in SLV mode. When the setting is
changed , reset (RS terminal on/off) is to be
executed so that the motor constants are
re-calculated.
After the setting is done, please be sure to reset (terminal RS on/off) to recalculate
the motor constant.
Refrain from change the setting value suddenly (within 10%). Inverter may
overvoltage trip due to the rapid change of output voltage.
Voltage compensation gain and slip compensation gain Using parameters A046 and
A047, you can obtain better performance under automatic torque boost mode (A041=01).
See following table for the concept of adjustment, including other parameters.

DC Braking (DB) Settings
Normal DC braking performance The DC
braking feature can provide additional
stopping torque when compared to a normal
deceleration to a stop. DC braking is
particularly useful at low speeds when
normal deceleration torque is minimal.
When you set A051 to 01 (Enable during stop), and the RUN command (FW/RV signal)
turns OFF, the inverter injects a DC voltage into the motor windings during
deceleration below a frequency you can specify (A052).
The braking power (A054) and duration (A055) can both be set. You can optionally specify
a wait time before DC braking (A053), during which the motor will free run.
DC Braking – Frequency Detection You can instead set DC braking to operate during
RUN mode only, by setting A051 to 02 (Frequency detection). In this case DC braking
operates when the output frequency comes down to the one you specified in A052 while
the RUN command is still active. Refer to the graphs figures below.
External DB and Internal DC braking are invalid during the frequency detection mode.
Example 1, (above left) shows the performance with A051=02 with a step-changing
frequency reference. In this case, when the reference goes to 0, the inverter immediately
starts DC braking because the set point drops below the value specified in A052. DC
braking continues until the set point exceeds A052. There will be no DC braking at next
downward transition because the FW input is OFF.
Example 2, (above right) shows a gradually changing frequency reference, for example
by analog input. In this case, there will be a DC braking period at starting because the
frequency set point is lower than the value specified in A052.

CAUTION: Be careful to avoid specifying a braking time that is long enough to cause
motor overheating. If you use DC braking, we recommend using a motor with a built-in
thermistor, and wiring it to the inverters thermistor input (see “Thermistor Thermal
Protection” in chapter 4). Also refer to the motor manufacturers specifications for
duty-cycle recommendations during DC braking.
DC braking performance at start can also be set separately (a057 and a058).
And carrier frequency of DC braking performance can also be set separately (a059).
CAUTION: Be careful to avoid specifying a braking carrier frequency that is high
enough to cause inverter and motor overheating. If you use DC braking, we recommend
using a motor with a built-in thermistor, and wiring it to the inverters thermistor input
(see “Thermistor Thermal Protection” in chapter 4). Also refer to the motor
manufacturer’s specifications for duty-cycle recommendations during DC braking.

Acceleration stop/Deceleration stop – The acceleration stop and deceleration stop
frequency setting allows you to make the inverter wait, upon starting the motor or upon
decelerating the motor, until the motor slip becomes less when the motor load causes a
large moment of inertia. Use this function if the inverter trips because of overcurrent
when starting or decelerating the motor. This function operates with every acceleration
and deceleration pattern, regardless the acceleration and deceleration curve selection
(A097 and A098). Instead of setting A069,A070,A154 and A155, acceleration and
deceleration can be held by intelligent input configured as "83:HLD".

In standard operation, the inverter uses a reference source selected by parameter A001
for the output frequency, which may be a fixed value (F001), a variable set by the front
panel potentiometer, or value from an analog input (voltage or current). To enable PID
operation, set A071=01. This causes the inverter to calculate
the target freq, or setpoint.
A calculated target frequency can have a lot of advantages. It lets the inverter adjust
the motor speed to optimize some other process of interest, potentially saving energy as
well. Refer to the figure below. The motor acts upon the external process. To control that
external process, the inverter must monitor the process variable. This requires wiring a
sensor to either the analog input terminal [O] (voltage) or terminal [OI] (current).
When enabled, the PID loop calculates the ideal output frequency to minimize the loop
error. This means we no longer command the inverter to run at a particular frequency,
but we specify the ideal value for the process variable. That ideal value is called the
setpoint, and is specified in the units of the external process variable. For a pump
application it may be gallons/minute, or it could be air velocity or temperature for an
HVAC unit. Parameter A075 is a scale factor that relates the external process variable
units to motor frequency. The figure below is a more detailed diagram of the function.

PID Loop Configuration
The inverter’s PID loop algorithm is configurable for various applications.
PID Output Limit - The PID loop controller has a built-in output limit function. This
function monitors the difference between the PID setpoint and the loop output (inverter
output frequency), measured as a percentage of the full scale range of each. The limit is
specified by parameter A078.
When the difference |(Setpoint – loop output)| is smaller than or equal to the A078
limit value, the loop controller operates in its normal linear range.
When the difference |(Setpoint – loop output)| is larger than the A078 limit value,
the loop controller changes the output frequency as needed so that the difference
does not exceed the limit.
The diagram below shows PID setpoint changes and the related output frequency
behavior when a limit value in A078 exists.
Deviation (error) Inversion - In typical heating loops or ventilation loops, an increase in
energy into the process results in an
increasing
PV. In this case, the Loop Error = (SP –
PV). For cooling loops, an increase in energy into the process results in a
decreasing
PV.
In this case, the Loop Error = –(SP – PV). Use A077 to configure the error term.

PID Sleep Function
The inverter shuts off the output when the PID output becomes less than the specified
value (A156) in case of PID is set enabled, or shuts off when the frequency command
becomes less than the specified value in case of PID is set disabled. And if the PID
output or frequency command exceeds the specified value (A156) for a specified period
(A157), inverter automatically restarts the operation. This is the PID sleep function.
PID Sleep function is always enabled, even the PID function is disabled.

Automatic Voltage Regulation (AVR) Function
The automatic voltage regulation (AVR) feature keeps the inverter output waveform at
a relatively constant amplitude during power input fluctuations. This can be useful if
the installation is subject to input voltage fluctuations. However, the inverter cannot
boost its motor output to a voltage higher than the power input voltage. If you enable
this feature, be sure to select the proper voltage class setting for your motor.

Note: The motor behave as generator during deceleration and the energy is regenerated to
the drive. As a result, the DC voltage in the inverter increases and cause over-voltage
trip when exceeding the OV level. When the voltage is set high, deceleration time can
be set shorter thanks to the energy consumption due to the incensement of loss in
inverter. In order to set deceleration time shorter without over-voltage trip, please try
to set AVR off during deceleration or to tune the AR filter time constant and AVR
deceleration gain.

Energy Savings Mode / Optional Accel/Decel
Energy Saving Mode – This function allows the inverter to deliver the minimum power
necessary to maintain speed at any given frequency. This works best when driving
variable torque characteristic loads such as fans and pumps. Parameter A085=01
enables this function and A086 controls the degrees of its effect. A setting of 0.0 yields
slow response but high accuracy, while a setting of 100 will yield a fast response with
lower accuracy.

The acceleration time is controlled so that the output current below the level set by the
Overload Restriction Function if enabled (Parameters b021, b022, and b023). If Overload
Restriction is not enabled, then the current limit used is 150% of the inverters rated
output current.
The deceleration time is controlled so that the output current is maintained below 150%
of the inverters rated current, and the DC bus voltage is maintained below the OV Trip
level (400V or 800V).
NOTE: If the load exceeds the rating of the inverter, the acceleration time may be increased.
NOTE: If using a motor with a capacity that is one size smaller than the inverter rating,
enable the Overload Restriction function (b021) and set the Overload Restriction Level
(
b022) to 1.5 times the motor nameplate current.
NOTE: Be aware that the acceleration and deceleration times will vary, depending on the
actual load conditions during each individual operation of the inverter.
NOTE: When analog input is a source of frequency command, be sure to set analog filter
A016=31 (500ms). Otherwise, there can be the case that this energy saving function doesn’t
work well.

Second Acceleration and Deceleration Functions
The WJ200 inverter features two-stage acceleration and deceleration ramps. This gives
flexibility in the profile shape. You can specify the frequency transition point, the point
at which the standard acceleration (F002) or deceleration (F003) changes to the second
acceleration (a092) or deceleration (a093). Or, you can use intelligent input [2CH] to
trigger this transition. These profile options are also available for the second motor
settings. Select a transition method via a094 as depicted below. Be careful not to confuse

“B” Group: Fine Tuning Functions
The “B” Group of functions and parameters adjust some of the more subtle but useful
aspects of motor control and system configuration.
Automatic Restart Mode
The restart mode determines how the inverter will resume operation after a fault
causes a trip event. The five options provide advantages for your applications.
Frequency matching allows the inverter to read the motor speed by virtue of its residual
magnetic flux and restart the output at the corresponding frequency. The inverter can
attempt a restart a certain number of times depending on the particular trip event:
Over-current trip, restart up to 3 times
Over-voltage trip, restart up to 3 times
When the inverter reaches the maximum number of restarts (3), you must power cycle
the inverter to reset its operation.
Other parameters specify the allowable under-voltage level and the delay time before
restarting. The proper settings depend on the typical fault conditions for your
application, the necessity of restarting the process in unattended situations, and
whether restarting is always say.
If the actual power failure time is
shorter than the B002 set value,
inverter resumes from the set
frequency in B011.
The resumption mode is called
“active frequency matching” and
the inverter performs reduced
voltage start to avoid over-current
trip.
If the motor current exceeds the
B030 set value during this period,
the inverter decelerates according
to the B029 set value and helps to
reduce the motor current.
When the motor current is less
than B030, the inverter increases
motor speed toward the set speed.
The inverter continues this retry
process until the motor speed
comes to the previous set speed.
Overload restriction (B021~B028) is not valid when active frequency matching is
activated.
If the actual power failure time is longer than the B002 set value, the inverter does not
resume and the motor will coast to stop.

Electronic Thermal Overload Alarm Setting
The thermal overload detection protects the inverter and motor from overheating due to
an excessive load. It uses a current/inverse time curve to determine the trip point.
First, use B013 to select the torque characteristic that matches your load. This allows
the inverter to utilize the best thermal overload characteristic for your application.
The torque developed in a motor is directly proportional to the current in the windings,
which is also related to the heat generated (and temperature, over time).
Therefore, you must set the thermal overload threshold in terms of current (amperes)
for parameter B012. The range is 20% to 100% of the rated current for each inverter
model. If the current exceeds the level you specify, the inverter will trip and log an event
(error E 05) in the history table. The inverter turns the motor output OFF when tripped.
Separate settings are available for the second motor (if applicable) as shown in the
following table.

WARNING: When parameter B012, level of electronic thermal setting, is set to motor
FLA rating (Full Load Ampere nameplate rating), the inverter provides solid state
motor overload protection at 115% of motor FLA or equivalent. If parameter B012
exceeds the motor FLA rating, the motor may overheat and be damaged. Parameter
B012, level of electronic thermal setting, is a variable parameter.

Electronic Thermal Warning Output: You can configure this function so that the
inverter outputs a warning signal before the electronic thermal protection operates
against motor overheat. You can also set the threshold level to output a warning signal
with the electronic thermal warning level setting in function “C061”.
To output the warning signal, assign parameter “13” (THM) to one of the intelligent
output terminals [11] to [12] (C021 to C022), or to the relay output terminal (C026).

Current limitation Related Functions
Overload Restriction: B022 If the inverters
output current exceeds a preset current level
you specify during acceleration or constant
speed, the overload restriction feature
automatically reduces the output frequency
during powering drive (and can increase the
speed during regeneration) to restrict the
overload. This feature does not generate an
alarm or trip event. You can instruct the
inverter to apply overload restriction only
during constant speed, thus allowing higher
currents for acceleration. Or, you may use the
same threshold for both acceleration and
constant speed.
You can specify two types of overload restriction operation by setting functional items
B021, B022, B023, and B024, B025, B026 separately. To switch between these two is done
by assigning “39 (OLR)” to an intelligent input terminal and make it ON/OFF.
When the inverter detects an overload, it must decelerate the motor to reduce the
current until it is less than the threshold. You can choose the rate of deceleration that
the inverter uses to lower the output current.
Over-current Trip Suppression: B027 The
Over-current Trip Suppression function
monitors the motor current and actively
changes the output frequency profile to
maintain the motor current within the limits.
Although “LAD” refers to “linear acceleration /
deceleration”, the inverter only “STOPs” the
acceleration and deceleration ramp so that it
will not cause an over-current trip event.
The graph at right shows an inverter output
profile that starts acceleration to a constant
speed. At two different points during the
acceleration, motor current increases and
exceeds the fixed level of Over-current Trip
Suppression level.
When the Over-current Trip Suppression feature is enabled by B027 = 01, the inverter
stops the acceleration ramp in each case until the motor current level is again less than
the threshold value, which is approximately 180% of the rated current of the inverter.
When using the Over-current Trip Suppression feature, please note the following:
When the feature is enabled (B027 = 01), the actual acceleration may be longer
than the value set by parameters F002/F202 in some cases.
The Over-current Trip Suppression feature does not operate by maintaining a
constant motor current. So it is still possible to have an over-current trip event
during extreme acceleration.

Software Lock Mode
The software lock function keeps personnel from accidentally changing parameters in
the inverter memory. Use B031 to select from various protection levels.
The table below lists all combinations of B031 option codes and the
ON/OFF state of the [SFT] input. Each Check
or Ex U indicates
whether the corresponding parameter(s) can be edited. The
Standard Parameters column below shows access in permitted for
some lock modes. These refer to the parameter tables throughout
this chapter, each of which includes a column titled
Run Mode Edit
as shown to the right.
The marks (Check
or Ex U) under the “Run Mode Edit” column title indicate
whether access applies to each parameter as defined in the table below. In some lock
modes, you can edit only F001 and the Multi-speed parameter group that includes A020,
A220, A021A035, and A038 (Jog). However, it does not include A019, Multi-speed

Motor Cable Length Parameter
To achieve higher motor control performance, the WJ200 inverter has the Motor Cable
Length Parameter setting B033. Normally there is no need to adjust this parameter,
however in case of long motor cable and/or shielded cable, where there is a
comparatively higher earth capacitance, set this parameter higher to achieve better
motor control performance.
Note that the parameter is indicative and no formula to calculate the suitable value.
Normally, longer the motor cable, bigger the set value. Please adjust depending on your
system.
For 11 and 15kW inverter, it is not needed to set b033.

Rotation restriction related parameters
Rotation direction restriction: b035 The rotation direction restriction function allows
you to restrict the direction of the motor rotation. This function is effective regardless of
the specification of operation command input device (e.g., control terminal or integrated
operator). If an operation command to drive the motor in a restricted direction is given,
the inverter (display) shows ( ).
Reverse run protection: b046 The reverse run protection function is effective when
03 (sensorless vector control)” or “04 (0-SLV)” is specified for the V/F characteristic
selection (A044). For control reasons, especially during motor operation at low speed, the
inverter may output a frequency that instructs the motor to rotate in the direction
opposite to that specified by the operation command.

Torque Limit Function
Torque limit function allows you to limit the motor output when 03 (SLV) is set for the

with the torque limit selection (b040).
(1) Quadrant-specific setting mode (b040=00)
In this mode, individual torque limit value to be applied to four quadrants (i.e.
forward powering, reverse regeneration, reverse powering and forward
regeneration) are set as the torque limits 1 to 4 (b041 to b044), respectively.
(2) Terminal-switching mode(b040=01)
In this mode, the torque limit values set in the torque limits 1 to 4 (b041 to b044)
are switched from one another according to the combination of the states of torque
limit switch terminals 1 and 2 (TRQ1 and TRQ2) assigned to intelligent input
terminals. A single selected torque limit is valid in all the operating states.
(3) Analog voltage input mode(b040=02)
In this mode, the torque limit value is set by a voltage applied to the control circuit
terminal O. The voltage range 0 to 10V corresponds to the torque limit value range
0 to 200%. A single selected torque limit is valid in all the operating states.
If parameter “40 (TL: whether to enable torque limitation)” has been assigned to any
intelligent input terminal, the torque limit mode selected by the setting of b040 is
enabled only when the TL terminal is turned ON. When the TL terminal is turned OFF,
torque limit settings are invalid, and the maximum torque setting is applied as a torque
limit.
It the TL function has not been assigned to the intelligent input terminal, the torque
limit mode selected by the setting of b040 is always enabled.
Each torque limit value used for this function is expressed as a ratio of the maximum
torque generated when the inverter outputs its maximum current on the assumption
that the maximum torque is 200%.
Note that each torque limit value does not represent an absolute value of torque. The
actual output torque varies depending on the motor.
It the torque limited signal function (TRQ) is assigned to an intelligent output terminal,
the TRQ signal will turn ON when the torque limit function operates.
100% torque is referred to inverter rated current. Absolute torque value is up the motor
to be combined.

Controlled Stop Operation at Power Loss
Controlled stop operation at power loss helps avoid tripping or free-running (coasting)
of the motor when power is lost while in run mode. The inverter controls the internal
DC bus voltage while decelerating the motor, and brings the motor to a controlled stop.
Should power be lost while the inverter is in run mode, this function will have the
following effect:
When the internal DC bus voltage of the inverter comes down to the set level of
B051, the inverter decreases the output frequency by the amount set in B054.
(During this interval the DC bus voltage rises due to regeneration, so does not reach
the UV level.)
The inverter then continues deceleration according to the value set in B053. If the
DC bus voltage rises up to the set value of B052, the inverter stops deceleration to
avoid OV tripping.
During this interval, the DC bus voltage decreases again due to lack of input power.
When the DC bus voltage comes down to the set value of B051, the inverter starts
deceleration according to the set value of B053 again. This process will be repeated
as needed until the motor is brought to a stop.

NOTE: If the DC bus voltage comes down to the UV level during this operation, the
inverter trips with under-voltage and motor will free-run (coast) to a stop.
NOTE: If the set value of B052<B051, then the inverter internally swaps the B052 and
B051 values. However the displayed values are not changed.
NOTE: This function cannot be interrupted until it is completed. So if the power is
restored during this operation, wait until the operation is done (motor stops) and then
give the run command.

Window Comparator, Analog disconnection
The window comparator function outputs signals when the values of analog inputs O
and OI are within the maximum and minimum limits specified for the window
comparator. You can monitor analog inputs with reference to arbitrary levels (to find
input terminal disconnection and other errors).
You can specify a hysteresis width for the maximum-limit and minimum-limit levels of
the window comparator. You can also specify limit levels and a hysteresis width
individually for analog inputs O and OI.
You can fix the analog input data to be applied to an arbitrary value when WCO or
WCOI is output. For this purpose, specify a desired value as the operation level at O/OI
disconnection (b070/b071/b072). When “no” is specified, the analog input data is
reflected as input.
Output values of Odc and OIDc are the same as those of WCO and WCOI, respectively.

Carrier frequency (PWM) related
Carrier frequency adjustment: B083 The internal
switching frequency
of the inverter
circuitry (also called the
chopper frequency
). It is called the carrier frequency because
the lower AC power frequency of the inverter “rides” the carrier. The faint, high-pitched
sound you hear when the inverter is in Run Mode is characteristic of switching power
supplies in general. The carrier frequency is adjustable from 2.0kHz to 15kHz. The
audible sound decreases at the higher frequencies, but RFI noise and leakage current
may be increased. Refer to the specification derating curves in Chapter 1 to determine
the maximum allowable carrier frequency setting for your particular inverter and
environmental conditions. Refer also to B089 for automatic carrier frequency reduction.
NOTE: The carrier frequency setting must stay within specified limits for
inverter-motor applications that must comply with particular regulatory agencies. For
example, European CE-approved application requires the carrier to be 3kHz or less.
Automatic carrier frequency reduction: B089 The automatic carrier frequency
reduction automatically reduces the carrier frequency according to the increase in
output current. To enable this function, specify “01” for automatic carrier frequency
reduction selection (b089).
When the output current increases to 60%,
72%, 84%, or 96% of the rated current, this
function reduces the carrier frequency to 12,
9, 6, or 3 kHz, respectively. This function
restores the original carrier frequency when
the output decreases to 5% lower than each
reduction start level.
The rate of carrier frequency reduction is
2kHz per second. The maximum limit of
carrier frequency change by this function is
the value specified for the carrier frequency setting (b083); the minimum limit is 3 kHz.
Note: If 3 kHz or less freq. has been specified for b083, this function is disabled
regardless of the setting of b089.

Miscellaneous Settings
The miscellaneous settings include scaling factors, initialization modes, and others.
This section covers some of the most important settings you may need to configure.
Start frequency adjustment: B082 When the inverter starts to run, the output
frequency does not ramp from 0Hz. Instead, it steps directly to the
start frequency
(B082), and the ramp proceeds upward from there.
Initialization related: B084, B085, B094, B180 These functions allow you to restore the
factory default settings. Please refer toRestoring Factory Default Settings
” in chapter
6.
Stop key enable function: B087 This function allows you to decide whether the stop
key on the integrated operator is enabled or not.
Dynamic Braking related functions: B090, B095, B096, – These parameters are for using
the internal brake chopper so to get more regeneration torque of the motor.
Cooling Fan Control: B092 You can select the performance of the cooling fan (if your
inverter model includes a fan). This function controls whether the cooling fan stops or
keeps on running after the inverter stops the motor. This can result in an additional
energy saving and extends fan life.

372
Stop Mode / Restart Mode Configuration: B091/B088 You can configure how the
inverter performs a standard stop (each time Run FWD and REV signals turn OFF).
Setting B091 determines whether the inverter will control the deceleration, or whether
it will perform a free-run stop (coast to a stop). When using the free-run stop selection,
it is imperative to also configure how you want the inverter to resume control of motor
speed. Setting B088 determines whether the inverter will ensure the motor always
resumes at 0 Hz, or whether the motor resumes from its current coasting speed (also
called
active frequency matching
). The run command may turn OFF briefly, allowing
the motor to coast to a slower speed from which normal operation can resume.
In most applications a controlled deceleration is desirable, corresponding to B091=00.
However, applications such as HVAC fan control will often use a free-run stop (B091=01).
This practice decreases dynamic stress on system components, prolonging system life.
In this case, you will typically set B088=01 in order to resume from the current speed
after a free-run stop (see diagram down below: active frequency matching resume). Note
that using the default setting, B088=00, can cause trip events when the inverter
attempts to force the load quickly to zero speed.
NOTE: Other events can cause (or be configured to cause) a free-run stop, such as power
loss (see “Automatic Restart Mode” on page 3-32), or an intelligent input terminal [FRS]
signal. If all free-run stop behavior is important to your application (such as HVAC), be
sure to configure each event accordingly.
373
An additional parameter further configures
all instances of a free-run stop. Parameter
B003, Retry Wait Time Before Motor Restart,
sets the minimum time the inverter will
free-run. For example, if B003 = 4 seconds
(and B091=01) and the cause of the free-run
stop lasts 10 seconds, the inverter will
free-run (coast) for a total of 14 seconds
before driving the motor again.
The figure at below right describes how
active frequency matching resume operates.
After waiting the time set in B003, the
inverter tries to catch the speed of the motor
shaft and outputs the speed set in B030. At
this time, if the motor current rises up to the
value set in B028, the inverter decreases the
frequency according to the deceleration time
set in B029, and finally comes to the required
speed. Following are the related parameters
for this control.

Brake Control Function Related
The brake control function allows you to make the inverter control an external brake
used for a lift or other machines. To enable this function, specify “01” (enabling the
brake control function) for the Brake Control Enable (b120). This function operates as
described below.
(1) When the inverter receives an operation command, it starts the output and
accelerates the motor up to the Brake Release Frequency Setting.
(2) After the Brake Release Frequency Setting is reached, the inverter waits for the
braking wait time (b121), and then outputs the brake release signal (BOK). However,
if the inverter output current has not reached the brake release current (b126), the
inverter does not output the brake release signal, but trips and outputs a brake
error signal (BER).
(3) When the braking confirmation signal (BOK) has been assigned to an intelligent
input terminal (that is, when “44” is specified for one of “C001” to “C007”), the
inverter waits for the Brake Wait Time for Confirmation (b124) without accelerating
the motor after receiving the brake release signal. If the inverter does not receive
the braking confirmation signal within the braking confirmation time (b124), it trips
with the braking error signal (BER) output. When the braking confirmation signal
(BOK) has not been assigned to any intelligent input terminal, the Brake Wait Time
for Confirmation (b124) is invalid. In such cases, the inverter proceeds to the
operation described in item (4) after the output of the brake release signal.
(4) After the input of the braking confirmation signal (or the output of the brake release
signal [when the BOK signal function is disabled]), the inverter waits for the Brake
Wait Time for Acceleration (b122), and then starts accelerating the motor up to the
set acceleration frequency.
(5) When the operation command is turned off, the inverter decelerates the motor down
to the braking frequency (b125), and then turns off the brake release signal (BRK).
(1) Time to reach Brake release freq.
(2) Brake Wait Time for Release (b121)
(3) Brake Wait Time for Confirmation (b124)
(4) Brake Wait Time for Acceleration (b122)

(6) When the braking confirmation signal (BOK) has been assigned to an intelligent
input terminal (that is, when “44” is specified for one of “C001” to “C007”), the
inverter waits, after turning off the brake release signal, until the braking
confirmation is turned off at least for the Brake Wait Time for Confirmation (b124)
without decelerating the motor. If the braking confirmation signal is not turned off
within the Brake Wait Time for Confirmation (b124), the inverter trips with the
braking error signal (BER) output. When the braking confirmation signal (BOK)
has not been assigned to any intelligent input terminal, the Brake Wait Time for
Confirmation (b124) is invalid. In such cases, the inverter proceeds to the operation
described in item (7) after the brake release signal is turned off.
(7) After the braking confirmation signal (or the brake release signal [when the BOK
signal function is disabled]) is turned off, the inverter waits for the Brake Wait Time
for Stopping (b123), and then starts decelerating the motor down to 0Hz.
NOTE: The above timing chart shows the operation on the assumption that the braking
confirmation signal “44” (BOK) is assigned to one of the terminal 1 to 7 (C001~C007). If
the BOK signal is not assigned to any terminal, the Brake Wait Time for Acceleration
(b122) begins when the brake release signal is turned on, and the Brake Wait Time for
Stopping (b123) begins when the brake release signal is turned off.
When using the brake control function, assign the following signal functions to
intelligent input and output terminals as needed.
To input a signal indicating that the brake is released from the external brake to the
inverter, assign the braking confirmation signal (44: BOK) to one of the terminal 1~7
(C001~C007)
Assign the brake release signal (19: BRK), which is a brake-releasing command, to
one of the output terminal 11~12 (C021~C022). To output a signal when braking is
abnormal, assign the brake error signal (20: BER) to an output terminal.
377

DC Bus AVR (Automatic Voltage Regulation) for Deceleration Settings
This function is to achieve stable DC
bus voltage in case of deceleration. DC
bus voltage rises due to regeneration
during deceleration. When this
function is activated (B130=01 or 02),
inverter controls the deceleration time
so that the DC bus voltage not to go up
to the overvoltage trip level, and leads
to the trip-less operation during
deceleration.
Please note that the actual
deceleration time can be longer in this
case.

Inverter Mode Setting
Besides Dual rating selection (b049), WJ200 supports two different operation modes,
standard mode and high frequency IM mode.
In high frequency IM mode, the max. output frequency is up to 1000Hz. Be sure to set
HD mode (b049=00) at first before switching to high frequency mode. In high frequency
mode, it cannot be changed to ND mode.
In high frequency mode, SLV mode is not available.
The inverter mode cannot be changed just setting b171. After setting b171, be sure to
execute initialization to activate new mode.
Actual inverter mode can be monitored with d060.
Once high frequency mode is set, initialization can be done just by setting b084,
b085, b094 and setting b180, it is not needed to set b171 .

“C” Group: Intelligent Terminal Functions
The seven input terminals [1], [2], [3], [4], [5], [6], and [7] can be configured for any of 72
different functions. The next two tables show how to configure the seven terminals. The
inputs are logical, in that they are either OFF or ON. We define these states as OFF=0,
and ON=1.
The inverter comes with default options for the seven terminals. These settings are
initially unique, each one having its own setting. Note that European and US versions
have different default settings. You can use any option on any terminal, and even use
the same option twice to create a logical OR (though usually not required).
NOTE: Terminals [3] and [4] have the ability to be logical inputs, and to be safety inputs
in case of safe stop function is selected.
NOTE: Terminal [5] has the ability to be a logical input, and to be an analog input for a
thermistor device when PTC function (option code 19) is assigned to that terminal.
Input Terminal Configuration
Functions and Options – The
function codes
in the following table let you assign one of
seventy-two options to any of the seven logic inputs for the XJ200 inverters. The
functions C001 through C007 configure the terminals [1] through [7] respectively. The
“value” of these particular parameters is not a scalar value, but it is a discrete number
that selects one option from many available
options
.
For example, if you set function C001=00, you have assigned option 00 (Forward Run) to
terminal [1]. The option codes and the specifics of how each one works are in Chap. 4.

Intelligent Input Terminal Overview
Each of the seven intelligent terminals may be assigned any of the options in the
following table. When you program one of the option codes for terminal assignments
C001 to C007, the respective terminal assumes the function role of that option code. The
terminal functions have a symbol or abbreviation that we use to label a terminal using
that function. For example, the “Forward Run” command is [FW]. The physical label on
the terminal block connector is simply 1, 2, 3, 4, 5, 6, or 7. However, schematic examples
in this manual also use the terminal symbol (such as [FW]) to show the assigned option.
The option codes for C011 to C017 determines the active state of the logical input (active
high or active low).

pulse train input (C027=15), scale
conversion is set in C047.
Pulse-out = Pulse-in × (C047)
Set range is 0.01 to 99.99

The output logic conversion is programmable for terminal [11], [12] and the alarm relay
terminal. The open-collector output terminal [11] and [12] defaults to normally open (active
low), but you can select normally closed (active high) for the terminal in order to invert the
sense of the logic. You can invert the logical sense of the alarm relay output as well.

NOTE: If you are using the output terminal OFF delay feature (any of C145, C149 > 0.0
sec.), the [RS] (reset) terminal affects the ON-to-OFF transition slightly. Normally (with
using OFF delays), the [RS] input causes the motor output and the logic outputs to turn
OFF together, immediately. However, when any output uses an OFF delay, then after
the [RS] input turns ON, that output will remain ON for an additional 1 sec. period
(approximate) before turning OFF.

Low Load Detection Parameters
The following parameters work in
conjunction with the intelligent output
function, when configured. The output
mode parameter (C038) sets the mode of
the detection at which the low load
detection signal [LOC] turns ON. Three
kinds of modes can be selected. The
detection level parameter (C039) is to set
the level of the low load.
This function is for generating an early
warning logic output, without causing
either a trip event or a restriction of the
motor current (those effects are available
on other functions).

Output Function Adjustment Parameters
Overload Warning Output - The following
parameters work in conjunction with the
intelligent output function, when configured.
The overload level parameter (C041) sets the
motor current level at which the overload
signal [OL] turns ON. The range of setting is
from 0% to 200% of the rated current for the
inverter. This function is for generating an
early warning logic output, without causing
either a trip event or a restriction of the
motor current (those effects are available on
other functions).
Frequency Arrival Output - The frequency
arrival signal, [FA1] or [FA2], is intended to
indicate when the inverter output has
reached (arrived at) the target frequency.
You can adjust the timing of the leading and
trailing edges of the signal via two
parameters specified to acceleration ad
deceleration ramps, C042 and C043. Refer
also to chapter 4.
PID FBV Output - The Error for the PID
loop is the magnitude (absolute value) of
the difference between the Set point
(desired value) and Process Variable
(actual value). The PID output deviation
signal [OD] (output terminal function
option code 04) indicates when the error
magnitude has exceeded a magnitude you
define.
Over/Under-torque Output – The inverter outputs the over/under-torque signal when it
detects that the estimated motor output torque exceeds the specified level. To enable
this function, assign parameter “07” (OTQ: over/under-torque signal) to an intelligent
output terminal. Over-torque or under-torque can be selected by function C054.
This function is effective only when the V/F characteristic curve selection “A044” or
A244” is the sensorless vector control or 0Hz range sensorless vector control. With any
other V/F characteristic curve is selected, the output of the OTQ signal is unpredictable.
When using the inverter for a lift, use the OTQ signal as the trigger to stop braking.
Use the frequency arrival signal as the trigger to start braking.

Electronic Thermal Warning Output –Please refer to page 3-39 for detailed information.
Zero speed detection Output – The inverter outputs the 0Hz speed detection signal
when the inverter output frequency falls below the threshold frequency specified in the
zero speed detection level (C063).
To use this function, assign parameter “21” to one of the intelligent output terminals
[11] to [12] (C021 to C022), or to the alarm relay output terminal (C026).
This function applies to the inverter output frequency when the V/F characteristic
curve selection is based on the constant torque (VC), reduced torque (VP), free-V/F,
sensorless vector control, or 0Hz range sensorless vector control.
Heat Sink Overheat Warning Output – The inverter monitors the temperature of its
heat sink, and outputs the heat sink overheat warning (OHF) signal when the
temperature exceeds the heat sink overheat warning level specified in parameter C064.

Output Logic and Timing
Logic Output Function – The inverter has a built-in logic output feature. Select any two
operands out of all intelligent output options except LOG1~LOG3 and their operator out
of AND, OR, or XOR (exclusive OR). The terminal symbol for the new output is [LOG].
Use C021, C022 or C026 to route the logical result to terminal [11], [12] or the relay
terminals. LOG1-LOG3, no, OPO cannot be the operand.
The following table shows all four possible input combinations with each of the three

Motor Constants Selection
Adjust the motor constant settings to the motor to be driven by the inverter.
When using a single inverter to drive multiple motors in the control mode based on VC,
VP, or free V/F characteristics, calculate the total capacity of the motors, and specify a
value close to the total capacity for the motor capacity selection (H003/H203).
When the automatic torque boost function is used, the motor constant settings that do
not match with the motor may result in a reduced motor torque, or unstable motor
operation.
You can select the motor constants that are used when the control mode is the
sensorless vector control (hereafter “SLV”) from the following three types.
(1) Motor constants of Hitachi standard induction motor
When H002/H202=00, motor constants in H020/H220 to H024/H224 are taken. The
initial values in H020/H220 to H024/H224 are Hitachi standard motor's values.
(2) Motor constants obtained by off-line auto-tuning
When H002/H202=02, motor constants in H030/H230 to H034/H234 are taken, which are
obtained by off-line auto-tuning.
(3) Arbitrarily set motor constants
In above (1) and (2) cases, motor constants can be adjusted manually. According to
value of H002/H202, change motor constants in H020/H220 to H024/H224 or H030/H230 to
H034/H234 if necessary.
*1) Convert the inertia (J) to the motor shaft value. Bigger J value will result in a quicker
in motor response and quicker in torque increase. Smaller J value will result in the
opposite way.
*2) In the SLV modes, inverter may give out reverse to given operation command in the
low speed range as a nature of those controls. In case there is a specific inconvenience
for example reverse rotation damages the machine, enable the reverse run protection
(b046).
3107
Sensorless Vector Control
This sensorless vector control enables the inverter to accurately operate the motor with
a high starting torque, even at low speed. It estimates and controls the motor speed and
output torque based on the inverter output voltage, output current, and the set motor
constants on the inverter. To use this function, specify “03” for the V/F characteristic
curve selection (A044/A2444).
In prior to use this function, be sure to make optimum setting of the motor constants,
which is described before.
When using this function, observe the following precautions:
(1) If you use the inverter to drive a motor of which the capacity is two class lower than
the maximum applicable capacity of the inverter, you may not be able to obtain
adequate motor characteristics.
(2) If you cannot obtain the desired characteristics from the motor driven under the
SLV control, readjust the motor constants according to the symptom, as described in
the table below.

Note 1) When driving a motor of which the capacity is one class lower than the inverter,
adjust the torque limit (b041 to b044) so that the value “α” calculated by the
expression below does not exceed 200%. Otherwise, the motor may not be burnt.
α = “torque limit” x (inverter capacity) / (motor capacity)
(Example) When the inverter capacity is 0.75kW and the motor capacity is 0.4kW,
the torque limit value is calculated as follows, based on the
assumption that the value α should be 200%:
Torque limit (b041 to b044) = α x (motor capacity) / (inverter capacity)
= 2.0 x (0.4kW)/(0.75kW) = 106%
3108
Auto-tuning Function
The WJ200 inverter has auto-tuning function to get suitable motor control performance
by measuring the motor constants automatically. Auto-tuning is effective only
sensorless vector control.
Auto-tuning with motor stop (H001=01)
Motor does not rotate while auto-tuning. If rotating motor could give harm to your
application, use this mode. But the motor constant I
0
(no-load current) and J
(inertia) are not measured and remain unchanged. (I
0
can be monitored in 50Hz of
V/f operation.)
Auto-tuning with motor rotation (H001=02)
Motor rotates according to a special operation pattern while auto-tuning. However,
the torque during auto-tuning is not sufficient, which may cause a problem in the
load (for example, a lift may slide down). See below instruction 7)-d).
When using auto-tuning function, follow the instructions below.
1) When using a motor which constants are unknown, execute offline auto-tuning to obtain the
constants.
2) When the motor constant selection (H002/H202) is Hitachi std. motor (01), the initial values in
H020/H220 to H024/H224 are Hitachi standard motor's values. If Hitachi std. motor is used, full
performance is achieved without auto-tuning in most cases.
3) The motor constant data is corresponding to one-phase of Y (star) connection for 50Hz.
4) Set base frequency (A003) and AVR voltage (A082) according to the motor specifications. If the
motor voltage is other than the alternatives, set V/f gain (A045) according to below formula.
“motor voltage (A082)” × “output voltage gain (A045)” = “motor rated voltage”
5) Proper motor constants are obtained only when the same size or one size lower motor is used.
If other size of motor is connected, proper values may not be obtained or auto-tuning operation
may not be completed. In this case, press STOP/RESET key, then error code will be displayed.
6) Be sure to disable DC braking setting (A051=00) and simple positioning selection (P012=00),
otherwise motor constants are not measured properly.
7) Be sure to deactivate ATR terminal (52:Enable torque cmd. input), otherwise motor constants
are not measured properly.
8) If auto-tuning with motor rotation (H001=02) is used, check the followings points.
a) The motor rotates up to 80% of base frequency. Check if it is no problem for the application.
b) The motor should not be driven by any other external force.
c) All the brakes should be released.
d) During auto-tuning, insufficient torque may cause a problem in the load (for example, a lift
may slide down). In this case, remove the motor from the machine or other load, and
perform auto-tuning with the motor alone. The measured inertia J is based on the motor
alone. To apply the data, add the moment of inertia of the load machine to the measured J
data after converting the moment of inertia to the motor shaft data.
e) If the application is with limitat
ion (e.g. lift or boring machine), the allowable rotation limit
may be exceeded in auto-tuning, and the machine may be damaged.
9) Even when “01 (auto-tuning without motor rotation)” is selected, the motor could rotate
slightly during auto-tuning.
10) When performing the auto-tuning with one lower size of motor, enable the overload restriction
function, and set the overload restriction level to 150% of the rated current of the motor.
11) When deceleration over-voltage suppress integral time (b134) is small, auto-tuning may result
3109
in over-voltage trip. In this case, increase b134 and retry the auto-tuning.
12) To execute auto-tuning, be sure to set the output frequency (F001) larger than starting
frequency (b082) regardless with or without rotation.
3110
Off-line auto-tuning procedure (with motor rotation)
(Note 2) After auto-tuning is completed, be sure to set 01 in H002/H202, otherwise measured data is
not effective.
(Note 3) Speed "X" of above (5) depends on accel/deceleration time. (T: Larger time of accel or
deceleration time)
0 < T < 50 [s] : X=40%
50 T < 100 [s] : X=20%
100 T [s] : X=10%
(Note 4) If auto-tuning is failed, try to execute again.
(Note 5) If the inverter trips during the auto-tuning, the auto-tuning is interrupted. After removing
the cause of trip, retry auto-tuning from the beginning.
(Note 6) If inverter is stopped during auto-tuning by stop command (by STOP key or deactivate RUN
input), measured constants could remain. Be sure to execute auto-tuning again.
(Note 7) If auto-tuning is attempted in free V/f setting, auto-tuning will fail with error display.

Simple positioning setting
- Set 03” in [EA] selection (P003), then pulse train input is used as feedback signal from encoder.
- Set "02" in simple positioning selection (P012), then simple positioning is enabled. (If "00" is set, "V/f
control with FB" is enabled. Please refer to xx for further information.
- Up to 8 position data are commanded by combination of 3 input terminals configured as CP1 to
CP3.
- Besides positioning input, RUN command (FW,RV) is necessary. Since rotation direction does not
matter for positioning, both FW and RV work as RUN command.
- Positioning speed depends on frequency source (A001).
- More than four digits are required for positioning data, but only four higher digits are displayed.

In the simple positioning mode, the inverter runs the motor until the machine reaches
the target position according to the following settings, and then stops the motor with
DC braking.
<1> Position setting
<2> Speed setting (frequency setting)
<3> Acceleration and deceleration time
(DC braking state is held until RUN command is turned off.)
-
I
n simple positioning mode, the frequency and acceleration/deceleration are according to current
settings as same as normal operation.
- Depending on DC braking and creep speed setting, positioning may go off the point.
- If the position value specified by the position setting is small, the inverter may decelerate the
motor for positioning before its speed reaches the speed setting.
- In simple positioning mode, the rotation direction setting (FW or RV) of the operation
command is ignored. The operation command simply functions as the signal to run or stop the
motor. The motor runs in the forward direction when the value of “target position” –(minus)
“current position” is positive, or in the reverse position when the value is negative.
- The position at power up is home position (Position data = 0). If power is removed, current
position data is lost.
- When the operation command is turned on with 0 specified as the position setting, positioning
is completed (with DC braking) without running the motor.
- Specify 03 (only to reset a trip)” for reset mode selection (C102). If a value other than “03” is
specified to C102, the current position counter will be cleared when the inverter reset terminal (or
reset key) is turned on. Be sure to specify “03” for reset mode selection (C102) if you intend to use
the value of the current position counter for operation after recovering the inverter from tripping
by turning on the reset terminal (or reset key).
- If the PCLR function is assigned to a input terminal, turning it on to clear the current position
counter.
- In simple positioning mode, ATR terminal is invalid. (Torque control does not work.)
- If current position is out of the set range, inverter will be tripped (E83) and coasting status.

Multistage position switching function (CP1/CP2/CP3)
When functions “66 (CP1)” to “68 (CP3)” are assigned to input terminal [1] to [7] (C001 to
C008), you can select multistage positions 0 to 7. Preset position data 0 to 7 in P060 to
P067. If no assignment is set in terminals, position command will be position-0 (P060).

To avoid misinput due to time lag of each input, you can adjust the determination time
in (C169). The input status is taken the preset time (C169) after the last change of input
status. (Note that a long determination time deteriorates the input response.)
