Speed/positioning switching function (SPD)
- Set SPD terminal ON, then speed control is enabled in simple positioning mode.
- While SPD terminal is ON, current position counter is 0. When SPD is turned OFF,
the inverter starts positioning operation.
- If positioning command data is 0 at SPD turning OFF, the inverter start deceleration
immediately. (Depending on DC braking setting, motor could be hunting.)
- While SPD terminal is ON, rotating direction depends on RUN command. Be sure to
check rotating direction after switching to positioning operation.

Introduction
The previous material in Chapter 3 gave a reference listing of all the programmable
functions of the inverter. We suggest that you first scan through the listing of inverter
functions to fain a general familiarity. This chapter will build on that knowledge in the
following ways:
1. Related functions – Some parameters interact with or depend on the settings in
other functions. This chapter lists “required settings” for a programmable function to
serve as a cross-reference and an aid in showing how function interacts.
2. Intelligent terminals – Some functions rely on an input signal on a control logic
connector terminal, or generate output signals in other cases.
3. Electrical interfaces – This chapter shows how to make connections between the
inverter and other electrical devices.
4. Auto Tuning Performance – This chapter shows how to perform auto tuning so to
achieve good performance of the motor control.
5. Positioning Performance – This chapter shows how to realize simple positioning by
using encoder (PG) feedback.
6. PID Loop Operation – The WJ200 has a built-in PID loop that calculates the optimal
inverter output frequency to control an external process. This chapter shows the
parameters and input/output terminals associated with PID loop operation.
7. Multiple motors – A single WJ200 inverter may be used with two or more motors in
some types of applications. This chapter shows the electrical connections and inverter
parameters involved in multiple-motor applications.
The topics in this chapter can help you decide the features that are important to your
application, and how to use them. The basic installation covered in Chapter 2
concluded with the powerup test and running the motor. Now, this chapter starts from
that point and shows how to make the inverter part of a larger control or automation
system.
Caution Messages for Operating Procedures
Before continuing, please read the following Caution messages.
CAUTION: The heat sink fins will have a high temperature. Be careful not to touch
them. Otherwise, there is the danger of getting burned.
CAUTION: The operation of the inverter can be easily changed from low speed to high
speed. Be sure to check the capability and limitations of the motor and machine before
operating the inverter. Otherwise, it may cause injury to personnel.
CAUTION: If you operate a motor at a frequency higher than the inverter standard
default setting (50Hz/60Hz), be sure to check the motor and machine specifications
with the respective manufacturer. Only operate the motor at elevated frequencies after
getting their approval. Otherwise, there is the danger of equipment damage.
43
Warning Messages for Operating Procedures
WARNING: Be sure to turn ON the input power supply only after closing the front case.
While the inverter is energized, be sure not to open the front case. Otherwise, there is
the danger of electric shock.
WARNING: Be sure not to operate electrical equipment with wet hands. Otherwise,
there is the danger of electric shock.
WARNING: While the inverter is energized, be sure not to touch the inverter terminals
even when the motor is stopped. Otherwise, there is the danger of electric shock.
WARNING: If the retry mode is selected, the motor may suddenly restart after a trip
stop. Be sure to stop the inverter before approaching the machine (be sure to design the
machine so that safety for personnel is secure even if it restarts.) Otherwise, it may
cause injury to personnel.
WARNING: If the power supply is cut OFF for a short period of time, the inverter may
restart operating after the power supply recovers if the Run command is active. If a
restart may pose danger to personnel, so be sure to use a lock-out circuit so that it will
not restart after power recovery. Otherwise, it may cause injury to personnel.
WARNING: The Stop Key is effective only when the stop function is enabled. Be sure to
enable the Stop Key separately from the emergency stop. Otherwise, it may cause
injury to personnel.
WARNING: During a trip event, if the alarm reset is applied and the Run command is
present, the inverter will automatically restart. Be sure to apply the alarm reset only
after verifying the Run command is OFF. Otherwise, it may cause injury to personnel.
WARNING: Be sure not to touch the inside of the energized inverter or to put any
conductive object into it. Otherwise, there is a danger of electric shock and/or fire.
WARNING: If power is turned ON when the Run command is already active, the motor
will automatically start and injury may result. Before turning ON the power, confirm
that the RUN command is not present.
WARNING: When the Stop key function is disabled, pressing the Stop key does not
stop the inverter, nor will it reset a trip alarm.
WARNING: Be sure to provide a separate, hard-wired emergency stop switch when the
application warrants it.
44
Connecting to PLCs and Other Devices
Hitachi inverters (drives) are useful in many types of applications. During installation,
the inverter keypad (or other programming device) will facilitate the initial
configuration. After installation, the inverter will generally receive its control
commands through the control logic connector or serial interface from another
controlling device. In a simple application such as single-conveyor speed control, a
Run/Stop switch and potentiometer will give the operator all the required control. In a
sophisticated application, you may have a
programmable logic controller
(PLC) as the
system controller, with several connections to the inverter.
It is not possible to cover all the possible types of application in this manual. It will be
necessary for you to know the electrical characteristics of the devices you want to
connect to the inverter. Then, this section and the following sections on I/O terminal
functions can help you quickly and safely connect those devices to the inverter.
CAUTION: It is possible to damage the inverter or other devices if your application
exceeds the maximum current or voltage characteristics of a connection point.
The connections between the inverter and
other devices rely on the electrical
input/output characteristics at both ends of
each connection, shown in the diagram to the
right. The inverter’s configurable inputs
accept either a sourcing or sinking output
from an external device (such as PLC). This
chapter shows the inverters internal
electrical component(s) at each I/O terminal.
In some cases, you will need to insert a
power source in the interface wiring.
In order to avoid equipment damage and get
your application running smoothly, we
recommend drawing a schematic of each
connection between the inverter and the
other device. Include the internal
components of each device in the schematic,
so that it makes a complete circuit loop.
After making the schematic, then:
1. Verify that the current and voltage for
each connection is within the operating
limits of each device.
2. Make sure that the logic sense (active high or active low) of any ON/OFF
connection is correct.
3. Check the zero and span (curve end points) for analog connections, and be sure the
scale factor from input to output is correct.
4. Understand what will happen at the system level if any particular device suddenly
loses power, or powers up after other devices.

Using Intelligent Input Terminals
Terminals [1], [2], [3], [4], [5], [6] and [7] are identical, programmable inputs for
general use. The input circuits can use the inverter’s internal (isolated) +24V field
supply or an external power supply. This section describes input circuits operation and
how to connect them properly to switches or transistor outputs on field devices.
The WJ200 inverter features selectable
sinking
or
sourcing
inputs. These terms refer
to the connection to the external switching device–it either
sinks
current (from the
input to GND) or
sources
current (from a power source) into the input. Note that the
sink/source naming convention may be different in your particular country or industry.
In any case, just follow the wiring diagrams in this section for your application.
The inverter has a short bar (jumper) for
configuring the choice of sinking or
sourcing inputs. To access it, you must
remove the front cover of the inverter
housing. In the figure to the top right, the
short bar is shown as attached to the logic
terminal block (connector). For EU and US
version (suffix –xFE, and –xFU), it is
originally located as source type logic. If
you need to change to the sink type
connection, remove the short bar and
connect it as shown in the figure at the
bottom right.
CAUTION: Be sure to turn OFF power to the inverter before changing the short circuit
bar position. Otherwise, damage to the inverter circuitry may occur.
[PLC] Terminal Wiring – The [PLC]
terminal (Programmable Logic Control
terminal) is named to include various
devices that can connect to the
inverter’s logic inputs. In the figure to
the right, note the [PLC] terminal and
the short bar (jumper). Locating the
short bar between [PLC] and [L] sets
the input logic source type, which is the
default setting for EU and US versions.
In this case, you connect input terminal
to [P24] to make it active. If instead you
locate the short bar between [PLC] and
[P24], the input logic will be sink type.
In this case, you connect the input
terminal to [L] to make it active.
The wiring diagram on the following pages show the four combinations of using
sourcing or sinking inputs, and using the internal or an external DC supply.

The power to the inverter control part can be supplied externally as shown below.
Except driving motor, it is possible read and write the parameters by keypad and via
communication even the drive itself is not powered.
By having ability inverter doesn’t block the current flowing into itself when it is not
powered. This may cause the closed circuit when two or more inverters are connected to
common I/O wiring as shown below to result in unexpected turning the on the input. To
avoid this closed circuit, please put the diode (rated:50V/0.1A) in the path as described

Notes:
When the Forward Run and Reverse Run

When a terminal associated with either [FW] or
[RV] function is configured for normally closed,
the motor starts rotation when that terminal is
disconnected or otherwise has no input voltage.
NOTE: The parameter F004, Keypad Run Key Routing, determines whether the single
Run key issues a Run FWD command or Run REV command. However, it has no effect
on the [FW] and [RV] input terminal operation.
WARNING: If the power is turned ON and the Run command is already active, the
motor starts rotation and is dangerous! Before turning power ON, confirm that the Run
command is not active.

Multi-Speed Select ~Binary Operation
The inverter can store up to 16 different target
frequencies (speeds) that the motor output uses for
steady-state run condition. These speeds are
accessible through programming four of the
intelligent terminals as binary-encoded inputs CF1 to
CF4 per the table to the right. These can be any of the
six inputs, and in any order. You can use fewer inputs
if you need eight or fewer speeds.
NOTE: When choosing a subset of speeds to use,
always start at the top of the table, and with the
least-significant bit: CF1, CF2, etc.
The example with eight speeds in the
figure below shows how input switches
configured for CF1–CF3 functions can
change the motor speed in real time.

While using the multi-speed capability, you can monitor the present frequency with
monitor function D001 during each segment of a multi-speed operation.
NOTE: When using the Multi-speed Select settings CF1 to CF4, do not display
parameter F001 or change the value of F001 while the inverter is in Run Mode (motor
running). If it is necessary to check the value of F001 during Run Mode, please monitor
D001 instead of F001.
There are two ways to program the speeds into the registers A020 to A035:
1. Standard keypad programming:
a. Select each parameter A020 to A035.
b. Press the SET key to view the parameter value.
c. Use the U and V keys to edit the value.
d. Use the SET key to save the data to memory.
2. Programming using the CF switches. Set the speed by following these steps:
a. Turn the Run command OFF (Stop Mode).
b. Turn inputs ON to select desired Multi-speed. Display the value of F001 on the
digital operator.
c. Set the desired output frequency by pressing the U and V keys.
d. Press the SET key once to store the set frequency. When this occurs,
F001 indicates the output frequency of Multi-speed n.
e. Press the SET key once to confirm that the indication is the same as the set
frequency.
f. Repeat operations in 2. a) to 2. e) to set the frequency of other Multi-speeds. It
can be set also by parameters A020 to A035 in the first procedure 1. a) to 1. d).

Jogging Command
The Jog input [JG] is used to command
the motor to rotate slowly in small
increments for manual operation. The
speed is limited to 9.99 Hz. The
frequency for the jogging operation is
set by parameter A038. Jogging does
not use an acceleration ramp, so we
recommend setting the jogging
frequency A038 to 5 Hz or less to
prevent tripping.
When the terminal [JG] is turned ON
and the Run command is issued, the
inverter outputs the programmed jog
frequency to the motor. To enable the
Run key on the digital operator for jog
input, set the value 01 (terminal mode)
in A002 (Run command source).
The type of deceleration used to end a motor jog operation is selectable by
programming function A039. The options are:
00 valid during operation, Free-run stop (coasting)
01 valid during operation, Deceleration (normal level) and stop
02 valid during operation, Use DC braking and stop

External Signal for DC Braking
When the terminal [DB] is turned ON, the
DC braking feature is enabled. Set the
following parameters when the external DC
braking terminal [DB] is to be used:
A053 – DC braking delay time setting.
The range is 0.1 to 5.0 seconds.
A054 – DC braking force setting. The
range is 0 to 100%.
The scenarios to the right help show how DC
braking works in various situations.
1. Scenario 1 – The [FW] or [RV] terminal is
ON. When [DB] is ON, DC braking is
applied. When [DB] is OFF again, the
output frequency ramps to the prior level.
2. Scenario 2 – The Run command is applied
from the operator keypad. When the [DB]
terminal is ON, DC braking is applied.
When the [DB] terminal is OFF again, the
inverter output remains OFF.
3. Scenario 3 – The Run command is applied
from the operator keypad. When the [DB]
terminal is ON, DC braking is applied
after the delay time set by A053 expires.
The motor is in a free-running (coasting)
condition. When the [DB] terminal is OFF
again, the inverter output remains OFF.

Set Second Motor, Special Set
If you assign the [SET] function to an intelligent input terminal, you can select
between two sets of motor parameters. The second parameters store an alternate set of
motor characteristics. When the terminal [SET] is turned ON, the inverter will use the
second set of parameters to generate the frequency output to the motor. When
changing the state of the [SET] input terminal, the change will not take effect until the
inverter is stopped.
When you turn ON the [SET] input, the inverter operates per the second set of
parameters. When the terminal is turned OFF, the output function returns to the
original settings (first set of motor parameters). Refer to “Configuring the Inverter for
Multiple Motors” on page 4–58 for details.

Two Stage Acceleration and Deceleration
When terminal [2CH] is turned ON, the
inverter changes the rate of acceleration and
deceleration from the initial settings (F002
and F003) to use the second set of
acceleration/ deceleration values. When the
terminal is turned OFF, the inverter is
returned to the original acceleration and
deceleration time (F002 acceleration time 1,
and F003 deceleration time 1). Use A092
(acceleration time 2) and A093 (deceleration
time 2) to set the second stage acceleration
and deceleration times.
In the graph shown above, the [2CH] becomes active during the initial acceleration.
This causes the inverter to switch from using acceleration 1 (F002) to acceleration 2
(A092).

Free-run Stop
When the terminal [FRS] is turned ON, the inverter stops the output and the motor
enters the free-run state (coasting). If terminal [FRS] is turned OFF, the output
resumes sending power to the motor if the Run command is still active. The free-run
stop feature works with other parameters to provide flexibility in stopping and starting
motor rotation.
In the figure below, parameter B088 selects whether the inverter resumes operation
from 0 Hz (left graph) or the current motor rotation speed (right graph) when the [FRS]
terminal turns OFF. The application determines the best setting.

External Trip
When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates
error code E 12, and stops the output. This is a general purpose interrupt type feature,
and the meaning of the error depends on what you connect to the [EXT] terminal. Even
if the [EXT] input is turned OFF, the inverter remains in the trip state. You must reset
the inverter or cycle power to clear the error, returning the inverter to the Stop Mode.
In the graph below, the [EXT] input turns ON during normal Run Mode operation. The
inverter lets the motor free-run to a stop, and the alarm output turns ON immediately.
When the operator initiates a Reset command, the alarm and error are cleared. When
the Reset is turned OFF, the motor begins rotation since the Run command is already
active.

Unattended Start Protection
If the Run command is already set when power is turned ON, the inverter starts
running immediately after powerup. The Unattended Start Protection (USP) function
prevents that automatic startup, so that the inverter
will not
run without outside
intervention. When USP is active and you need to reset an alarm and resume running,
either turn the Run command OFF, or perform a reset operation by the terminal [RS]
input or the keypad Stop/reset key.
In the figure below, the [USP] feature is enabled. When the inverter power turns ON,
the motor does not start, even though the Run command is already active. Instead, it
enters the USP trip state, and displays E 13 error code. This requires outside
intervention to reset the alarm by turning OFF the Run command per this example (or
applying a reset). Then the Run command can turn ON again and start the inverter
output.

Commercial power source switchover
The commercial power source switching function allows you to switch the power supply
(between the inverter and commercial power supply) to your system of which the load
causes a considerable moment of inertia. You can use the inverter to accelerate and
decelerate the motor in the system and the commercial power supply to drive the motor
for constant speed operation.
To use this function, assign parameter “14 (CS)” to one of the intelligent input terminal
[1] to [7] (C001 to C007). When the CS is turned OFF with an operation command is
being given, the inverter waits for the retry wait time before motor starts (b003),
adjusts the output frequency to the speed of the free-running motor, and then
accelerates the motor with the adjusted frequency.
Mechanically interlock the MC3 and
MC2 contacts with each other.
Otherwise you may damage the drive.
If the earth leakage breaker (ELB) trips
because of a ground fault, the commercial
power will be disabled. Therefore, contact
a backup power supply from the
commercial power line circuit (ELBC) to
your system if needed.
Use weak-current type relays for FWY, RVY, and CSY. The figures below show the
sequence and timing of operations for reference.
If the inverter trips because of overcurrent when it starts the motor with frequency
matching, increase the retry wait time before motor starts (b003).

Reset Inverter
The [RS] terminal causes the inverter to execute
the reset operation. If the inverter is in Trip
Mode, the reset cancels the Trip state. When the
signal [RS] is turned ON and OFF, the inverter
executes the reset operation. The minimum pulse
width for [RS] must be 12 ms or greater. The
alarm output will be cleared within 30 ms after
the onset of the Reset command.
WARNING: After the Reset command is given and the alarm reset occurs, the motor
will restart suddenly if the Run command is already active. Be sure to set the alarm
reset after verifying that the Run command is OFF to prevent injury to personnel.

Notes:
While the control terminal [RS] input is ON, the
keypad displays alternating segments. After RS
turns OFF, the display recovers automatically.
Pressing the Stop/Reset key of the digital operator
can generate a reset operation only when an
alarm occurs.
A terminal configured with the [RS] function can only be configured for normally open operation. The
terminal cannot be used in the normally closed contact state.
When input power is turned ON, the inverter performs the same reset operation as it does when a pulse
on the [RS] terminal occurs.
The Stop/Reset key on the inverter is only operational for a few seconds after inverter powerup when a
hand-held remote operator is connected to the inverter.
If the [RS] terminal is turned ON while the motor is running, the motor will be free running (coasting).
If you are using the output terminal OFF delay feature (any of C145, C147, C149 > 0.0 sec.), the [RS]
terminal affects the ON-to-OFF transition slightly. Normally (without 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.

Thermistor Thermal Protection
Motors that are equipped with a thermistor can be protected from overheating. Input
terminal [5] has the unique ability to sense a thermistor resistance. When the
resistance value of the thermistor connected to terminal [PTC] (5) and [L] is more than
3 k ±10%, the inverter enters the Trip Mode, turns OFF the output to the motor, and
indicates the trip status E35. Use this function to protect the motor from overheating.

Three-wire Interface Operation
The 3-wire interface is an industry standard motor control interface. This function uses
two inputs for momentary contact start/stop control, and a third for selecting forward
or reverse direction. To implement the 3-wire interface, assign 20 [STA] (Start), 21
[STP] (Stop), and 22 [F/R] (Forward/Reverse) to three of the intelligent input terminals.
Use a momentary contact for Start and Stop. Use a selector switch, such as SPST for
the Forward/Reverse input. Be sure to set the operation command selection A002=01 for
input terminal control of motor.
If you have a motor control interface that needs logic-level control (rather than
momentary pulse control), use the [FW] and [RV] inputs instead.

Notes:
The STP logic is inverted. Normally the switch will
be closed, so you open the switch to stop. In this
way, a broken wire causes the motor to stop
automatically (safe design).
When you configure the inverter for 3-wire
interface control, the dedicated [FW] terminal is
automatically disabled. The [RV] intelligent
terminal assignment is also disabled.
The diagram below shows the use of 3-wire control. STA (Start Motor) is an
edge-sensitive input; an OFF-to-ON transition gives the Start command. The control of
direction is level-sensitive, and the direction may be changed at any time. STP (Stop

PID ON/OFF and PID Clear
The PID loop function is useful for controlling motor speed to achieve constant flow,
pressure, temperature, etc. in many process applications. The PID Disable function
temporarily suspends PID loop execution via an intelligent input terminal. It overrides
the parameter A071 (PID Enable) to stop PID execution and return to normal motor
frequency output characteristics. The use of PID Disable on an intelligent input
terminal is optional. Of course, any use of the PID loop control requires setting PID
Enable function A071=01.
The PID Clear function forces the PID loop integrator sum = 0. So, when you turn ON
an intelligent input configured as [PIDC], the integrator sum is reset to zero. This is
useful when switching from manual control to PID loop control and the motor is
stopped.
CAUTION: Be careful not to turn PID Clear ON and reset the integrator sum when the
inverter is in Run Mode (output to motor is ON). Otherwise, this could cause the motor
to decelerate rapidly, resulting in a trip.

Remote Control Up and Down Functions
The [UP] [DWN] terminal functions can adjust the output frequency for remote control
while the motor is running. The acceleration time and deceleration time of this function
is same as normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals
operate according to these principles:
Acceleration - When the [UP] contact is turned ON, the output frequency accelerates
from the current value. When it is turned OFF, the output frequency maintains its
current value at that moment.
Deceleration - When the [DWN] contact is turned ON, the output frequency
decelerates from the current value. When it is turned OFF, the output frequency
maintains its current value at that moment.
In the graph below, the [UP] and [DWN] terminals activate while the Run command
remains ON. The output frequency responds to the [UP] and [DWN] commands.

determination time setting (C169). The input data is finally determined when the
terminal input becomes stable after the delay set as C169. (Note that a long
determination time deteriorates the input terminal response.)

Limit signal of homing, Trigger signal of zero-return
These functions are used for homing performance.
One of three types of homing operations can be selected by homing mode selection
(P068). When a homing operation ends, the current position counter is cleared (to 0).
Use homing direction selection (P069) to select the direction of homing operation. If
homing operation is not performed, position control is performed based on the
assumption that the motor position detected at power-on is the origin.

Speed/position changeover
To perform speed control operation in absolute position control mode, turn on the SPD
terminal. While the SPD terminal is off, the current position count remains at 0.
Therefore if the SPD terminal is turned off during operation, the control operation is
switched to position control operation based on the position where the terminal is
turned off. (Speed control operation is switched to position control operation.)
If the position setting is 0 at this time, the inverter stops the motor at that position.
(Hunting may occur if a certain position loop gain value has been set.)
While the SPD terminal is on, the rotating direction depends on the operation
command. When switching from speed control to position control, pay attention to the
sign of the value set in the operation command.

Using Intelligent Output Terminals
The intelligent output terminals are programmable in a similar way to the intelligent
input terminals. The inverter has several output functions that you can assign
individually to two physical logic outputs. One of the outputs is an open-collector
transistor, and the other output is the alarm relay (form C – normally open and
normally closed contacts). The relay is assigned the alarm function by default, but you
can assign it to any of the functions that the open-collector output uses.
Sinking Outputs, Open Collector
The open-collector transistor
output can handle up to 50mA. We
highly recommend that you use an
external power source as shown at
the right. It must be capable of
providing at least 50mA to drive
the output at full load. To drive
loads that require more than
50mA, use external relay circuits
as shown below right.
Sinking Outputs, Open Collector
If you need output current greater
than 50mA, use the inverter output
to drive a small relay. Be sure to
use a diode across the coil of the
relay as shown (reverse-biased) in
order to suppress the turn-off spike,
or use a solid-state relay.

Internal Relay Output
The inverter has an internal relay output with
normally open and normally closed contacts
(Type 1 form C). The output signal that
controls the relay is configurable; the Alarm
Signal is the default setting. Thus, the
terminals are labeled [AL0], [AL1], [AL2], as
shown to the right. However, you can assign
any one of the nine intelligent outputs to the
relay. For wiring purposes, the general
terminal functions are:
[AL0] – Common contact
[AL1] – Normally open contact
[AL2] – Normally closed contact
The relay itself can be configured as “normally open or closed.” Parameter C036, Alarm
Relay Active State, is the setting. This setting determines whether or not the relay coil
is energized when its output signal is OFF:
C036=00 – “Normally open” (relay coil is de-energized when output signal is OFF)
C036=01 – “Normally closed” (relay coil is energized when the output signal is OFF)
Since the relay already has normally open
[AL1] and normally closed [AL2] contacts, the
purpose of the ability to invert the relay coil’s
active state may not be obvious.
It allows you to
determine whether or not an inverter power
loss causes the relay to change state.
The
default relay configuration is the Alarm Signal
(C026=05), as shown to the right. And, C036=01
sets the relay to “normally closed” (relay coil
normally energized). The reason for this is that
a typical system design will require an inverter
power loss to assert an alarm signal to external
devices.
The relay can be used for other intelligent
output signals, such as the Run Signal (set
C026=00). For these remaining output signal
types, the relay coil typically must NOT change
state upon inverter power loss (set C036=00).
The figure to the right shows the relay settings
for the Run Signal output.
If you assign the relay an output signal other
than the Alarm Signal, the inverter can still
have an Alarm Signal output. In this case, you
can assign it to terminal [11] , providing an
open collector output.

Output Signal ON/OFF Delay Function
Intelligent outputs including terminals [11], and the output relay, have configurable
signal transition delays. Each output can delay either the OFF-to-ON or ON-to-OFF
transitions, or both. Signal transition delays are variable from 0.1 to 100.0 seconds.
This feature is useful in applications that must tailor inverter output signals to meet
timing requirements of certain external devices.
The timing diagram below shows a sample output signal (top line) and the results of
various ON/OFF delay configurations.
Original signal - This example signal waveform consists of three separate pulses
named “A,” “B,” and “C.”
...with ON delay - Pulse A is delayed by the duration of the ON delay time. Pulses B
and C do not appear at the output, because they are shorter than the ON delay.
...with OFF delay - Pulse A is lengthened by the amount of the OFF delay time. The
separation between pulses B and C does not appear at the output, because it is
shorter than the OFF delay time.
...with ON/OFF delays - Pulse A is delayed on both leading and trailing edges by the
amounts of the ON and OFF delay times, respectively. Pulses B and C do not appear
at the output, because they are shorter than the ON delay time.

Frequency Arrival Signals
The
Frequency Arrival
group of outputs helps coordinate external systems with the
current velocity profile of the inverter. As the name implies, output [FA1] turns ON
when the output
frequency arrives
at the standard set frequency (parameter F001).
Output [FA2] relies on programmable accel/ decel thresholds for increased flexibility.
For example, you can have an output turn ON at one frequency during acceleration,
and have it turn OFF at a different frequency during deceleration. All transitions have
hysteresis to avoid output chatter if the output frequency is near one of the thresholds.

[FA2]

anticipates the threshold (turns ON early) by
1.5Hz
The output turns OFF as the output frequency
moves away from the threshold, delayed by
0.5Hz

Frequency arrival output [FA1] uses
the standard output frequency
(parameter F001) as the threshold for
switching. In the figure to the right,
Frequency Arrival [FA1] turns ON
when the output frequency gets within
Fon
Hz below or
Fon
Hz above the
target constant frequency, where
Fon
is
1% of the set maximum frequency and
Foff
is 2% of the set maximum
frequency. This provides hysteresis that
prevents output chatter near the
threshold value. The hysteresis effect
causes the output to turn ON slightly
early
as the speed approaches the
threshold. Then the turn-OFF point is
slightly
delayed
. Note the active low
nature of the signal, due to the open
collector output.
Frequency arrival output [FA2/FA4]
works the same way; it just uses two
separate thresholds as shown in the
figure to the right. These provide for
separate acceleration and deceleration
thresholds to provide more flexibility
than for [FA1]. [FA2/FA4] uses
C042/C045 during acceleration for the
ON threshold, and C043/C046 during
deceleration for the OFF threshold.
This signal also is active low. Having
different accel and decel thresholds
provides an asymmetrical output
function. However, you can use equal
ON and OFF thresholds, if desired.
Frequency arrival output [FA3/FA5]
works also the same way, only difference
is arriving at set frequency.

Alarm Signal
The inverter alarm signal is active when a fault has
occurred and it is in the Trip Mode (refer to the
diagram at right). When the fault is cleared the
alarm signal becomes inactive.
We must make a distinction between the alarm
signal
AL and the alarm relay
contacts
[AL0], [AL1]
and [AL2]. The signal AL is a logic function, which
you can assign to the open collector output terminals
[11], [12], or the relay outputs.
The most common (and default) use of the relay is for AL, thus the labeling of its
terminals. Use an open collector output (terminal [11] or [12]) for a low-current logic
signal interface or to energize a small relay (50 mA maximum). Use the relay output to
interface to higher voltage and current devices (10 mA minimum).

Notes:
By default, the relay is configured as normally

explanation.
In the default relay configuration, an inverter
power loss turns ON the alarm output. the alarm
signal remains ON as long as the external control
circuit has power.
When the relay output is set to normally closed, a
time delay of less than 2 seconds occurs after
powerup before the contact is closed.
Terminals [11] and [12] are open collector outputs,
so the electric specifications of [AL] are different
from the contact output terminals [AL0], [AL1],
[AL2].
This signal output has the delay time (300 ms
nominal) from the fault alarm output.
The relay contact specifications are in “Control

The alarm relay output can be configured in two main ways:
Trip/Power Loss Alarm – The alarm relay is configured as normally closed
(C036=01) by default, shown below (left). An external alarm circuit that detects
broken wiring also as an alarm connects to [AL0] and [AL1]. After powerup and
short delay (< 2 seconds), the relay energizes and the alarm circuit is OFF. Then,
either an inverter trip event or an inverter power loss will de-energize the relay
and open the alarm circuit
Trip Alarm – Alternatively, you can configure the relay as normally open (C036=00),
shown below (right). An external alarm circuit that detects broken wiring also as
an alarm connects to [AL0] and [AL2]. After powerup, the relay energizes only
when an inverter trip event occurs, opening the alarm circuit. However, in this
configuration, an inverter power loss does not open the alarm circuit.
Be sure to use the relay configuration that is appropriate for your system design. Note
that the external circuits shown assume that a closed circuit = no alarm condition (so
that a broken wire also causes an alarm). However, some systems may require a closed
circuit = alarm condition. In that case, then use the opposite terminal [AL1] or [AL2]
from the ones shown.

Analog Input Disconnect Detect
This feature is useful when the inverter receives a speed reference from an external
device. Upon input signal loss at either the [O] or [OI] terminal, the inverter normally
just decelerates the motor to a stop. However, the inverter can use the intelligent
output terminal [Dc] to signal other devices that a signal loss has occurred.
Voltage signal loss at [O] terminal - Parameter B082 is the Start Frequency
Adjustment. It sets the beginning (minimum) output frequency when the speed
reference source is greater than zero. If the analog input at terminal [O] is less than
the Start Frequency, the inverter turns ON the [Dc] output to indicate a signal loss
condition.
Current signal loss at [OI] terminal - The [OI] terminal accepts a 4mA to 20mA signal,
with 4mA representing the beginning of the input range. If the input current falls
below 4mA, the inverter applies a threshold to detect signal loss.
Note that a signal loss is not an inverter trip event. When the analog input value is again above
the
B082
value, the [Dc] output turns OFF. There is no error condition to clear.

PID Second Stage Output
The inverter has a built-in PID loop feature for
two-stage control,
useful for certain
applications such as building ventilation or heating and cooling (HVAC). In an ideal
control environment, a single PID loop controller (stage) would be adequate. However,
in certain conditions, the maximum output energy from the first stage is not enough to
maintain the Process Variable (PV) at or near the Setpoint (SP). And, the output of the
first stage is in saturation. A simple solution is to add a second stage, which puts an
additional and constant amount of energy into the system under control. When size
properly, the boost from the second stage brings the PV toward the desired range,
allowing the first stage PID control to return to its linear range of operation.
The two-stage method of control has some advantages for particular applications.
The second stage is only ON in adverse conditions, so there is an energy savings
during normal conditions.
Since the second stage is simple ON/OFF control, it is less expensive to add than just
duplicating the first stage.
At powerup, the boost provided by the second stage helps the process variable reach
the desired setpoint sooner than it would if the first stage acted alone.
Even though the second stage is simple ON/OFF control, when it is an inverter you
can still adjust the output frequency to vary the boost it provides.
Refer to the example diagram below. Its two stages of control are defined as follows:
Stage 1 - Inverter #1 operating in PID loop mode, with motor driving a fan
Stage 2 - Inverter #2 operating as an ON/OFF controller, with motor driving a fan
Stage #1 provides the ventilation needs in a building most of the time. On some days,
there is a change in the building’s air volume because large warehouse doors are open.
In that situation, Stage #1 alone cannot maintain the desired air flow (PV sags under
SP). Inverter #1 senses the low PV and its PID Second Stage Output at [FBV] terminal
turns ON. This gives a Run FWD command to Inverter #2 to provide the additional air
flow.
472
To use the PID Second Stage Output feature, you will need to choose upper and lower
limits for the PV, via C053 and C052 respectively. As the timing diagram below shows,
these are the thresholds Stage #1 inverter uses to turn ON or OFF Stage #2 inverter
via the [FBV] output. The vertical axis units are percent (%) for the PID setpoint, and
for the upper and lower limits. The output frequency, in Hz, is superimposed onto the
same diagram.
When the system control begins, the following events occur (in sequence in the timing
diagram):
1. Stage #1 inverter turns ON via the [FW] Run command.
2. Stage #1 inverter turns ON the [FBV] output, because the PV is below the PV low
limit C053. So, Stage #2 is assisting in loop error correction from the beginning.
3. The PV rises and eventually exceeds the PV high limit C052. Stage #1 inverter then
turns OFF the [FBV] output to Stage #2, since the boost is no longer needed.
4. When the PV begins decreasing, only Stage #1 is operating, and it is in the linear
control range. This region is where a properly configured system will operate most
often.
5. The PV continues to decrease until it crosses under the PV low limit (apparent
external process disturbance). Stage #1 inverter turns ON the [FBV] output, and
Stage #2 inverter is assisting again.
6. After the PV rises above the PV low limit, the [FW] Run command to Stage #1
inverter turns OFF (as in a system shutdown).
7. Stage #1 inverter enters Stop Mode and automatically turns OFF the [FBV] output,
which causes Stage #2 inverter to also stop.
The terminal [FBV] configuration table is on the following page.

Analog Input Operation
The WJ200 inverters provide for analog input
to command the inverter frequency output
value. The analog input terminal group
includes the [L], [OI], [O], and [H] terminals on
the control connector, which provide for Voltage
[O] or Current [OI] input. All analog input
signals must use the analog ground [L].
If you use either the voltage or current analog
input, you must select one of them using the
logic input terminal function [AT] analog type.
Refer to the table on next page showing the
activation of each analog input by combination
of A005 set parameter and [AT] terminal
condition. The [AT] terminal function is covered
in “Analog Input Current/Voltage Select” in
section 4. Remember that you must also set
A001 = 01 to select analog input as the
frequency source.
NOTE: If no logic input terminal is configured for the [AT] function, then inverter
recognizes that [AT]=OFF and MCU recognizes [O]+[OI] as analog input.
Using an external potentiometer is a common way
to control the inverter output frequency (and a good
way to learn how to use the analog inputs). The
potentiometer uses the built-in 10V reference [H]
and the analog ground [L] for excitation, and the
voltage input [O] for the signal. By default, the [AT]
terminal selects the voltage input when it is OFF.
Take care to use the proper resistance for the
potentiometer, which is 1~2 k
Ω, 2 Watts.
Voltage Input The voltage input circuit uses
terminals [L] and [O]. Attach the signal cable’s
shield wire only to terminal [L] on the inverter.
Maintain the voltage within specifications (do
not apply negative voltage).
Current Input The current input circuit uses
terminals [OI] and [L]. The current comes from a
sourcing
type transmitter; a
sinking
type will not
work! This means the current must flow into
terminal [OI], and terminal [L] is the return back
to the transmitter. The input impedance from
[OI] to [L] is 100 Ohms. Attach the cable shield
wire only to terminal [L] on the inverter.

Pulse Train Input Operation
The WJ200 inverter is capable of accepting pulse train input signals, that are used for
frequency command, process variable (feedback) for PID control, and simple positioning.
The dedicated terminal is called “EA” and “EB”. Terminal “EA” is a dedicated terminal,
and the terminal “EB” is an intelligent terminal, that has to be changed by a
parameter setting.
Terminal Name Description Ratings
EA Pulse train input A For frequency command, 32kHz max.
Common is [L]
EB
(Input terminal 7)
Pulse train input B
(Set C007 to 85 )
27Vdc max.
For frequency command, 2kHz max.
Common is [PLC]
(1) Frequency Command by pulse train input
When using this mode, you should set A001 to 06. In this case the frequency is detected
by input-capture, and calculated based on the ratio of designated max. frequency
(under 32kHz). Only an input terminal “EA” will be used in this case.
(2) Using for process variable of PID control
You can use the pulse train input for process variable (feedback) of PID control. In this
case you need to set A076 to 03. Only “EA” input terminal is to be used.
(3) Simple positioning by pulse train input
This is to use the pulse train input like an encoder signal. You can select three types of
operation.

Analog Output Operation
In inverter applications it is useful to monitor the
inverter operation from a remote location or from the
front panel of an inverter enclosure. In some cases,
this requires only a panel-mounted volt meter. In
other cases, a controller such as a PLC may provide
the inverter’s frequency command, and require
inverter feedback data (such as output frequency or
output current) to confirm actual operation. The
analog output terminal [AM] serves these purposes.
The inverter provides an analog voltage output on terminal [AM] with terminal [L] as
analog GND reference. The [AM] can output inverter frequency or current output value.
Note that the voltage range is 0 to +10V (positive-going only), regardless of forward or
reverse motor rotation. Use C028 to configure terminal [AM] as indicated below.

[AM] output gain 0.~255. 100.
C109
[AM] output offset 0.0~10.0 0.0
The graph below shows the effect of the gain and offset setting. To calibrate the [AM]
output for your application (analog meter), follow the steps below:
1. Run the motor at the full scale speed, or most common operating speed.
a. If the analog meter represents output frequency, adjust offset (C109) first, and
then use C106 to set the voltage for full scale output.
b. If [AM] represents motor current, adjust offset (C109) first, and then use BC106
to set the voltage for full scale output. Remember to leave room at the upper end
of the range for increased current when the motor is under heavier loads.
NOTE: As mentioned above, first adjust the offset, and then adjust the gain. Otherwise
the required performance cannot be obtained because of the parallel movement of the
offset adjustment.

Introduction
Introduction
A motor control system will obviously include a motor and inverter, as well as fuses for
safety. If you are connecting a motor to the inverter on a test bench just to get started,
that’s all you may need for now. But a fully developed system can also have a variety of
additional components. Some can be for noise suppression, while others may enhance
the inverter’s braking performance. The figure below shows a system with several
possible optional components, and the table gives part number information.

Component Descriptions
AC Reactors, Input Side
This is useful in suppressing harmonics induced on the power supply lines, or when the
main power voltage imbalance exceeds 3% (and power source capacity is more than 500
kVA), or to smooth out line fluctuations. It also improves the power factor.
In the following cases for a general-purpose inverter, a large peak current flows on the
main power supply side, and is able to destroy the inverter module:
If the unbalanced factor of the power supply is 3% or higher
If the power supply capacity is at least 10 times greater than the inverter capacity
(the power supply capacity is 500 kVA or more)
If abrupt power supply changes are expected
Examples of these situations include:
1. Several inverters are connected in parallel, sharing the same power bus
2. A thyristor converter and an inverter are connected in parallel, sharing the same
power bus
3. An installed phase-advance (power factor correction) capacitor opens and closes
Where these conditions exist or when the connected equipment must be highly reliable,
you MUST install an input-side AC reactor of 3% (at a voltage drop at rated current)
with respect to the supply voltage on the power supply side. Also, where the effects of
an indirect lightning strike are possible, install a lightning conductor.

AC Reactors, Output Side
This reactor reduces the vibrations in the motor caused by the inverter’s switching
waveforms, by smoothing the waveforms to approximate commercial power quality. It
is also useful to reduce the reflected voltage wave phenomenon when wiring from the
inverter to the motor is more than 10m in length. Please refer to the documentation
that comes with the AC reactor for installation instructions.
54
Zero-phase Reactor (RF Noise Filter)
The zero-phase reactor helps reduce radiated
noise from the inverter wiring. It can be used
on the input or output side of the inverter.
The example zero-phase reactor shown to the
right comes with a mounting bracket. The
wiring must go through the opening to reduce
the RF component of the electrical noise.
Loop the wires three times (four turns) to
attain the full RF filtering effect. For larger
wire sizes, place multiple zero-phase reactors
(up to four) side-by-side for a greater filtering
effect.
