Safety Messages

Please read the following safety messages before troubleshooting or performing

maintenance on the inverter and motor system.

WARNING: Wait at least ten (10) minutes after turning OFF the input power supply

before performing maintenance or an inspection. Otherwise, there is a danger of

electric shock.

WARNING: Make sure that only qualified personnel will perform maintenance,

inspection, and part replacement. Before starting to work, remove any metallic objects

from your person (wristwatch, bracelet, etc.). Be sure to use tools with insulated

handles. Otherwise, there is a danger of electric shock and/or injury to personnel.

WARNING: Never remove connectors by pulling on its wire leads (wires for cooling fan

and logic P.C.board). Otherwise, there is a danger of fire due to wire breakage and/or

injury to personnel.

Monitoring Trip Events, History, & Conditions

Fault Detection and Clearing

RUN

STOP

RESET

STOP

RESET

Tri

Fault

RUN

The microprocessor in the inverter detects a

variety of fault conditions and captures the event,

recording it in a history table. The inverter output

turns OFF, or “trips” similar to the way a circuit

breaker trips due to an over-current condition.

Most faults occur when the motor is running (refer

to the diagram to the right). However, the inverter

could have an internal fault and trip in Stop Mode.

In either case, you can clear the fault by pressing

the Stop/Reset key. Additionally, you can clear the

inverter’s cumulative trip history by performing

the procedure “Restoring Factory Default Settings”

on page 6–8 (setting B084=00 will clear the trip

history but leave inverter settings intact).

Fault

Error Codes

An error code will appear on the display automatically when a fault causes the inverter

to trip. The following table lists the cause associated with the error.

Erro

Code

Name Cause(s)

E01

Over-current event while at

constant speed

The inverter output was short-circuited, or the

motor shaft is locked or has a heavy load. These

conditions cause excessive current for the inverter,

so the inverter output is turned OFF.

The dual-voltage motor is wired incorrectly.

E02

Over-current event during

deceleration

E03

Over-current event during

acceleration

E04

Over-current event during

other conditions

E05

Overload protection When a motor overload is detected by the

electronic thermal function, the inverter trips and

turns OFF its output.

E06

Braking resistor overload

protection

When the BRD operation rate exceeds

the setting of "b090", this protective

function shuts off the inverter output and

displays the error code.

E07

Over-voltage protection When the DC bus voltage exceeds a threshold, due

to regenerative energy from the motor.

E08

EEPROM error When the built-in EEPROM memory has problems

due to noise or excessive temperature, the inverter

trips and turns OFF its output to the motor.

E09

Under-voltage error A decrease of internal DC bus voltage below a

threshold results in a control circuit fault. This

condition can also generate excessive motor heat or

cause low torque. The inverter trips and turns OFF

its output.

E10

Current detection error If an error occurs in the internal current

detection system, the inverter will shut off its

output and display the error code.

6−9

Error

Code

Name Cause(s)

E11

CPU error A malfunction in the built-in CPU has occurred, so

the inverter trips and turns OFF its output to the

motor.

E12

External trip A signal on an intelligent input terminal

configured as EXT has occurred. The inverter trips

and turns OFF the output to the motor.

E13

USP When the Unattended Start Protection (USP) is

enabled, an error occurred when power is applied

while a Run signal is present. The inverter trips

and does not go into Run Mode until the error is

cleared.

E14

Ground fault The inverter is protected by the detection of ground

faults between the inverter output and the motor

upon during powerup tests. This feature protects

the inverter, and does not protect humans.

E15

Input over-voltage The inverter tests for input over-voltage after the

inverter has been in Stop Mode for 100 seconds. If

an over-voltage condition exists, the inverter

enters a fault state. After the fault is cleared, the

inverter can enter Run Mode again.

E21

Inverter thermal trip When the inverter internal temperature is above

the threshold, the thermal sensor in the inverter

module detects the excessive temperature of the

power devices and trips, turning the inverter

output OFF.

E22

CPU communication error When communication between two CPU fails,

inverter trips and displays the error code.

E25

Main circuit

error (*3)

The inverter will trip if the power supply

establishment is not recognized because of a

malfunction due to noise or damage to the main

circuit element.

E30

Driver error An internal inverter error has occurred at the

safety protection circuit between the CPU and

main driver unit. Excessive electrical noise may be

the cause. The inverter has turned OFF the IGBT

module output.

E35

Thermistor When a thermistor is connected to terminals [5]

and [L] and the inverter has sensed the

temperature is too high, the inverter trips and

turns OFF the output.

E36

Braking error When "01" has been specified for the Brake Control

Enable (b120), the inverter will trip if it cannot

receive the braking confirmation signal within the

Brake Wait Time for Confirmation (b124) after the

output of the brake release signal.

E37

Safe Stop Safe stop signal is given.

E38

Low-speed overload protection If overload occurs during the motor operation at a

very low speed, the inverter will detect the

overload and shut off the inverter output.

Name Cause(s)

E40

Operator connection When the connection between inverter and

operator keypad failed, inverter trips and displays

the error code.

E41

Modbus communication error When “trip” is selected (C076=00) as a behavior in

case of communication error, inverter trips when

timeout happens.

E43

EzSQ invalid instruction The program stored in inverter memory has been

destroyed, or the PRG terminal was turned on

without a program downloaded to the inverter.

E44

EzSQ nesting count error Subroutines, if-statement, or for-next loop are

nested in more than eight layers

E45

EzSQ instruction error Inverter found the command which cannot be

executed.

E50

E59

EzSQ user trip (0 to 9) When user –defined trip happens, inverter trips

and displays the error code.

E60

Option error (DeviceNet

Communications error)

If the disconnection due to the Bus-Off signal or

timeout occurs during the operation using

DeviceNet commands, the inverter will shut off its

output and display the error code shown on the

right.

(The inverter will trip according to the settings of

"p45" and "P048".)

E61

Option error (duplicated MACID) If two or more devices having the same

MAC ID are detected in the same network, the

inverter will display the error code shown on the

right.

E62

Option error (External trip) If the Force Fault/Trip bit of Attribute 17 in the

Instance 1 of the Control Supervisory object is set

to "1", the inverter will shut off its output and

display the error code shown on the right.

E63 to

E68

Option error The inverter detects errors in the option board

mounted in the optional slot. For details, refer to

the instruction manual for the mounted option

board.

E69

Option error (inverter

communication error)

If timeout occurs during the communication

between the inverter and DeviceNet option board,

the inverter will shut off its output and display the

error code shown on the right.

E80

Encoder

disconnection

If the encoder wiring is disconnected, an encoder

connection error is detected, the encoder fails, or an

encoder that does not support line driver output is

used, the inverter will shut off its output and display

the error code shown on the right.

E81

Excessive speed If the motor speed rises to "maximum frequency

(A004) x over-speed error detection level (P026)" or

more, the inverter will shut off its output and

display the error code shown on the right.

E83

Trip History and Inverter Status

We recommend that you first find the cause of the fault before clearing it. When a fault

occurs, the inverter stores important performance data at the moment of the fault. To

access the data, use the monitor function (dxxx) and select d081 details about the

present fault. The previous 5 faults are stored in d082 to d086. Each error shifts

d081-d085 to d082-d086, and writes the new error to d081.

The following Monitor Menu map shows how to access the error codes. When fault(s)

exist, you can review their details by first selecting the proper function: D081 is the

most recent, and D086 is the oldest.

Restoring Factory Default Settings

You can restore all inverter parameters to the original factory (default) settings

according to area of use. After initializing the inverter, use the powerup test in Chapter

2 to get the motor running again. If operation mode (std. or high frequency) mode is

changed, inverter must be initialized to activate new mode. To initialize the inverter,

follow the steps below.

(1) Select initialization mode in b084.

(2) If b084=02, 03 or 04, select initialization target data in b094.

(3) If b084=02, 03 or 04, select country code in b085.

(4) Set 01 in b180.

Megger test

The

megger

is a piece of test equipment that uses a high voltage to determine if an

insulation degradation has occurred. For inverters, it is important that the power

terminals be isolated from the Earth GND terminal via the proper amount of

insulation.

The circuit diagram below shows the inverter wiring for performing the megger test.

Just follow the steps to perform the test:

1. Remove power from the inverter and wait at least 5 minutes before proceeding.

2. Open the front housing panel to access the power wiring.

3. Remove all wires to terminals [R, S, T, PD/+1, P/+, N/–, U, V, and W]. Most

importantly, the input power and motor wires will be disconnected from the inverter.

4. Use a bare wire and short terminals [R, S, T, PD/+1, P/+, N/–, U, V, and W] together

as shown in the diagram.

5. Connect the megger to the inverter Earth GND and to the shorted power terminals

as shown. Then perform the megger test at 500 VDC and verify 5MΩ or greater

resistance.

6. After completing the test, disconnect the megger from the inverter.

7. Reconnect the original wires to terminals [R, S, T, PD/+1, P/+, N/–, U, V, and W].

CAUTION: Do not connect the megger to any control circuit terminals such as

intelligent I/O, analog terminals, etc. Doing so could cause damage to the inverter.

CAUTION: Never test the withstand voltage (HIPOT) on the inverter. The inverter has

a surge protector between the main circuit terminals above and the chassis ground.

CAUTION: Power terminal assignment is different compared to old models such as

L100, L200 series, etc,. Pay attention when wiring the power cable.

IGBT Test Method

The following procedure will check the inverter transistors (IGBTs) and diodes:

1. Disconnect input power to terminals [R, S, and T] and motor terminals [U, V, and

W].

2. Disconnect any wires from terminals [+] and [–] for regenerative braking.

3. Use a Digital Volt Meter (DVM) and set it for 1Ω resistance range. You can check the

status of the charging state of terminals [R, S, T, U, V, W, +, and –] of the inverter

and the probe of the DVM by measuring the charging state.

Inverter Output Voltage Measurement Techniques

Taking voltage measurements around drives equipment requires the right equipment

and a safe approach. You are working with high voltages and high-frequency switching

waveforms that are not pure sinusoids. Digital voltmeters will not usually produce

reliable readings for these waveforms. And, it is usually risky to connect high voltage

signals to oscilloscopes. The inverter output semiconductors have some leakage, and

no-load measurements produce misleading results. So, we highly recommend using the

following circuits to measure voltage for performing the equipment inspections.

Capacitor Life Curves

The DC bus inside the inverter uses a large capacitor as shown in the diagram below.

The capacitor handles high voltage and current as it smoothes the power for use by the

inverter. So, any degradation of the capacitor will affect the performance of the

inverter.

Capacitor life is reduced in higher ambient temperatures, as the graph below

demonstrates. Under the condition of average ambient temperature 40degC, 80% load,

24 hours operation, the lifetime is 10years. Be sure to keep the ambient temperature at

acceptable levels, and perform maintenance inspections on the fan, heat sink, and

other components. If the inverter is installed on a cabinet, the ambient temperature is

the temperature inside the cabinet.

Glossary

mbient

emperature

The air temperature in the chamber containing a powered electronic

unit. A unit’s heat sinks rely on a lower ambient temperature in

order to dissipate heat away from sensitive electronics.

rrival Frequency

The arrival frequency refers to the set output frequency of the

inverter for the constant speed setting. The arrival frequency feature

turns on an output when the inverter reaches the set constant speed.

The inverter has various arrival frequencies and pulsed or latched

logic options.

uto-tuning

The ability of a controller to execute a procedure that interacts with

a load to determine the proper coefficients to use in the control

algorithm. Auto-tuning is a common feature of process controllers

with PID loops. Hitachi inverters feature auto tuning to determine

motor parameters for optimal commutation. Auto-tuning is available

as a special command from a digital operator panel. See also

Digital

Operator Panel

ase Frequency

The power input frequency for which an AC induction motor is

designed to operate. Most motors will specify a 50 to 60 Hz value.

The Hitachi inverters have a programmable base frequency, so you

must ensure that parameter matches the attached motor. The term

base frequency

helps differentiate it from the carrier frequency. See

also

Carrier Frequency

and

Frequency Setting

raking Resistor

An energy-absorbing resistor that dissipates energy from a

decelerating load. Load inertia causes the motor to act as a generator

during deceleration. For the X200 inverter models, the braking unit

and braking resistor are optional (external) components. See also

Four-quadrant Operation

and

Dynamic Braking.

reak-away Torque

The torque a motor must produce to overcome the static friction of a

load, in order to start the load moving.

Carrier Frequency

The frequency of the constant, periodic, switching waveform that the

inverter modulates to generate the AC output to the motor. See also

PWM

A regulatory agency for governing the performance of electronic

products in Europe. Drive installations designed to have CE

approval must have particular filter(s) installed in the application.

Choke

An inductor that is tuned to react at radio frequencies is called a

“choke,” since it attenuates (chokes) frequencies above a particular

threshold. Tuning is often accomplished by using a movable

magnetic core. In variable-frequency drive systems, a choke

positioned around high-current wiring can help attenuate harmful

harmonics and protect equipment. See also

Harmonics

A−3

C Braking

The inverter DC braking feature stops the AC commutation to the

motor, and sends a DC current through the motor windings in order

to stop the motor. Also called “DC injection braking,” it has little

effect at high speed, and is used as the motor is nearing a stop.

eadband

In a control system, the range of input change for which there is no

perceptible change in the output. In PID loops, the error term may

have a dead band associated with it. Deadband may or may not be

desirable; it depends on the needs of the application.

igital Operator

anel

For Hitachi inverters, “digital operator panel” (DOP) refers first to

the operator keypad on the front panel of the inverter. It also

includes hand-held remote keypads, which connect to the inverter

via a cable. Finally, the DOP Professional is a PC-based software

simulation of the keypad devices.

iode

A semiconductor device that has a voltage-current characteristic that

allows current to flow only in one direction, with negligible leakage

current in the reverse direction. See also

Rectifier

uty Cycle

1. The percent of time a square wave of fixed frequency is ON

(high) versus OFF (low).

2. The ratio of operating time of a device such as a motor to its

resting time. This parameter usually is specified in association

with the allowable thermal rise for the device.

ynamic Braking

For the X2002 inverter models, the braking unit and braking resistor

are optional (external) components. The dynamic braking feature

shunts the motor-generated EMF energy into a special braking

resistor. The added dissipation (braking torque) is effective at higher

speeds, having a reduced effect as the motor nears a stop.

output signal from inverter to external device in order to feed back

the status that the both safety path working properly. Safety

certificate is issued based on the condition that this EDM signal is

interfaced to certified external device to avoid restarting or to inform

in case of failure in safety path.

value or setpoint (SP) and the actual value of a the process variable

(PV). See also

EMI

Electromagnetic Interference - In motor/drive systems, the switching

of high currents and voltages creates the possibility of generating

radiated electrical noise that may interfere with the operation of

nearby sensitive electrical instruments or devices. Certain aspects of

an installation, such as long motor lead wire lengths, tend to

increase the chance of EMI. Hitachi provides accessory filter

components you can install to decrease the level of EMI.

our-quadrant

peration

Referring to a graph of torque versus direction, a four-quadrant drive

can turn the motor either forward or reverse, as well as decelerate in

either direction (see also

reverse torque

). A load that has a relatively

A−4

high inertia and must move in both directions and change directions

rapidly requires four-quadrant capability from its drive.

ree-run Stop

A method of stopping a motor, caused when the inverter simply

turns OFF its motor output connections. This may allow the motor

and load to coast to a stop, or a mechanical brake may intervene and

shorten the deceleration time.

requency Setting

While frequency has a broad meaning in electronics, it typically

refers to motor speed for variable-frequency drives (inverters). This

is because the output frequency of the inverter is variable, and is

proportional to the attained motor speed. For example, a motor with

a base frequency of 60 Hz can be speed controlled with an inverter

output varying form 0 to 60 Hz. See also

harmonic

is a whole number multiple of a base of fundamental

frequency. The square waves used in inverters produce high

frequency harmonics, even though the main goal is to produce

lower-frequency sine waves. These harmonics can be harmful to

electronics (including motor windings) and cause radiated energy

that interferes with nearby electronic devices. Chokes, line reactors,

and filters are sometimes used to suppress the transmission of

harmonics in an electrical system. See also

Choke

unit of time. You can directly convert between horsepower and Watts

as measurements of power.

A configurable input or output logic function on the Hitachi

inverters. Each terminal may be assigned one of several functions.

nverter

A device that electronically changes DC to AC current through an

alternating process of switching the input to the output, inverted

and non-inverted. A variable speed drive such as the Hitachi X200

is also called an inverter, since it contains three inverter circuits to

generate 3-phase output to the motor.

solation

ransformer

A transformer with 1:1 voltage ratio that provides electrical

isolation between its primary and secondary windings. These are

typically used on the power input side of the device to be protected.

An isolation transformer can protect equipment from a ground fault

or other malfunction of nearby equipment, as well as attenuate

harmful harmonics and transients on the input power.

Usually done manually, a jog command from an operator’s panel

requests the motor/drive system to run indefinitely in a particular

direction, until the machine operator ends the jog operation.

ump Frequency

jump frequency

is a point on the inverter output frequency range

that you want the inverter to skip around. This feature may be used

to avoid a resonant frequency, and you can program up to three jump

frequencies in the inverter.

ine Reactor

A three-phase inductor generally installed in the AC input circuit of

an inverter to minimize harmonics and to limit short-circuit current.

The physical property of a body in motion that causes it to remain in

motion. In the case of motors, the rotor and attached load are

rotating and possesses angular momentum.

the motor, and control motor speed according to the currently

selected speed preset. The Hitachi inverters have 16 preset speeds.

physical mass that is moved by the motor and the related friction

from guiding mechanisms. See also

electrical power and device wiring and installation in the United

States.

EMA

a published series of device ratings standards. Industry uses these to

evaluate or compare the performance of devices made by various

manufacturers to a known standard.

ower Factor

A ratio that expresses a phase difference (timing offset) between

current and voltage supplied by a power source to a load. A perfect

power factor = 1.0 (no phase offset). Power factors less than one

cause some energy loss in power transmission wiring (source to load).

ID Loop

Proportional - Integral-Derivative - A mathematical model used for

process control. A process controller maintains a process variable

(PV) at a setpoint (SP) by using its PID algorithm to compensate for

dynamic conditions and vary its output to drive the PV toward the

desired value. For variable-frequency drives, the process variable is

the motor speed. See also

Pulse-width modulation: A type of AC adjustable frequency drive

that accomplishes frequency and voltage control at the output section

(inverter) of the drive. The drive output voltage waveform is at a

constant amplitude, and by “chopping” the waveform (pulsewidth-

modulating), the average voltage is controlled. The chopping

frequency is sometimes called the

Carrier Frequency

eactance

The impedance of inductors and capacitors has two components. The

resistive part is constant, while the reactive part changes with

applied frequency. These devices have a complex impedance

(complex number), where the resistance is the real part and the

reactance is the imaginary part.

ectifier

An electronic device made of one or more diodes that converts AC

power into DC power. Rectifiers are usually used in combination

with capacitors to filter (smooth) the rectified waveform to closely

approximate a pure DC voltage source.

egenerative

raking

A particular method of generating reverse torque to a motor, an

inverter will switch internally to allow the motor to become a

generator and will either store the energy internally, deliver the

braking energy back to the main power input, or dissipate it with a

resistor.

egulation

The quality of control applied to maintain a parameter of interest at

a desired value. Usually expressed as a percent (±) from the nominal,

motor regulation usually refers to its shaft speed.

everse Torque

The torque applied in the direction opposite to motor shaft rotation.

As such, reverse torque is a decelerating force on the motor and its

external load.

otor

Saturation Voltage

For a transistor semiconductor device, it is in saturation when an

increase in input current no longer results in an increase in the

output current. The saturation voltage is the voltage drop across the

device. The ideal saturation voltage is zero.

Sensorless Vector

Control

A technique used in some variable-frequency drives (featured in

some other Hitachi inverter model families) to rotate the force vector

in the motor without the use of a shaft position sensor (angular).

Benefits include an increase in torque at the lowest speed and the

cost savings from the lack of a shaft position sensor.

Single-phase power

An AC power source consisting of Hot and Neutral wires. An Earth

Ground connection usually accompanies them. In theory, the voltage

potential on Neutral stays at or near Earth Ground, while Hot varies

sinusoidally above and below Neutral. This power source is named

Single Phase to differentiate it from three-phase power sources.

Some Hitachi inverters can accept single phase input power, but

they all output three-phase power to the motor. See also

hree-phase

Slip

The difference between the theoretical speed of a motor at no load

(determined by its inverter output waveforms) and the actual speed.

Some slip is essential in order to develop torque to the load, but too

much will cause excessive heat in the motor windings and/or cause

the motor to stall.

Squirrel Cage

A “nick-name” for the appearance of the rotor frame assembly for an

AC induction motor.

Stator

The windings in a motor that are stationary and coupled to the

power input of the motor. See also

Rotor

achometer

1. A signal generator usually attached to the motor shaft for the

purpose of providing feedback to the speed controlling device of

the motor.

2. A speed-monitoring test meter that may optically sense shaft

rotation speed and display it on a readout.

hermal Switch

An electromechanical safety device that opens to stop current flow

when the temperature at the device reaches a specific temperature

threshold. Thermal switches are sometimes installed in the motor in

order to protect the windings from heat damage. The inverter can

use thermal switch signals to trip (shut down) if the motor overheats.

See also

Trip

hermistor

A type of temperature sensor that changes its resistance according to

its temperature. The sensing range of thermistors and their

ruggedness make them ideal for motor overheating detection.

Hitachi inverters have built-in thermistor input circuits, which can

detect an overheated motor and shut off (trip) the inverter output.

hree-phase power

An AC power source with three Hot connections that have phase

offsets of 120 degrees is a 3-phase power source. Usually, Neutral

and Earth Ground wires accompany the three Hot connections.

Loads may be configured in a delta or Y configuration. A Y-connected

load such as an AC induction motor will be a balanced load; the

currents in all the Hot connections are the same. Therefore, the

Neutral connection is theoretically zero. This is why inverters that

generate 3-phase power for motors do not generally have a Neutral

connection to the motor. However, the Earth Ground connection is

important for safety reasons, and is provided.

A−8

orque

The rotational force exerted by a motor shaft. The units of

measurement consist of the distance (radius from shaft center axis)

and force (weight) applied at that distance. Units are usually given

as pound-feet, ounce-inches, or Newton-meters.

ransistor

A solid state, three-terminal device that provides amplification of

signals and can be used for switching and control. While transistors

have a linear operating range, inverters use them as high-powered

switches. Recent developments in power semiconductors have

produced transistors capable of handling high voltages and currents,

all with high reliability. The saturation voltage has been decreasing,

resulting in less heat dissipation. Hitachi inverters use

state-of-the-art semiconductors to provide high performance and

reliability in a compact package. See also

Saturation

Voltage

rip Event

An event that causes the inverter to stop operation is called a “trip”

event (as in

tripping

a circuit breaker). The inverter keeps a history

log of trip events. They also require an action to clear.

att Loss

A measure of the internal power loss of a component, the difference

between the power it consumes and what its output delivers. An

inverter’s watt loss is the input power minus the power delivered to

the motor. The watt loss is typically highest when an inverter is

delivering its maximum output. Therefore, watt loss is usually

specified for a particular output level. Inverter watt loss

specifications are important when designing enclosures.

Modbus connector is in control terminal block as below. Note that RJ45 connector

(RS-422) is used for external operator only.

Terminate Network Wiring - The RS-485 wiring must be terminated at each physical

end to suppress electrical reflections and help decrease transmission errors. WJ200 has

a built-in 200

Ω resistor activated by a dip switch. Select termination resistors that match

the characteristic impedance of the network cable. The diagram above shows a network

with the needed termination resistor at each end.

Network Protocol Reference

Transmission procedure

The transmission between the external control equipment and the inverter takes the

procedure below.

• Query - A frame sent from the external control equipment to the inverter

• Response - A frame returned from inverter to the external control equipment

The inverter returns the response only after the inverter receives a query from the

external control equipment and does not output the response positively. Each frame is

formatted (with commands) as follows:

Trailer (silent interval)

B−6

Message Configuration: Query

Slave address:

• This is a number of 1 to 32 assigned to each inverter (slave). (Only the inverter

having the address given as a slave address in the query can receive the query.)

• When slave address “0” is specified, the query can be addressed to all inverters

simultaneously. (Broadcasting)

• In broadcasting, you cannot call and loop back data.

• Slave Address 1-247 in Modbus specification. When master address the slave

250-254, broadcast toward specific slave address. Slave doesn’t answer back. And

this function is valid for the write command (05h, 06h, 0Fh, 10h)

Error check:

Modbus-RTU uses CRC (Cyclic Redundancy Check) for error checking.

• The CRC code is 16-bit data that is generated for 8-bit blocks of arbitrary length.

• The CRC code is generated by a generator polynomial CRC-16 (X16+ X15+ X2+ 1).

Header and trailer (silent interval):

Latency is the time between the reception of a query from the master and transmission

of a response from the inverter.

• 3.5 characters (24 bits) are always required for latency time. If the latency time

shorter than 3.5 characters, the inverter returns no response.

• The actual transmission latency time is the sum of silent interval (3.5 characters

long) + C078 (transmission latency time).

B−8

Message Configuration: Response

Transmission time required:

• A time period between reception of a query from the master and transmission of a

response from the inverter is the sum of the silent interval (3.5 characters long) +

C078 (transmission latency time).

• The master must provide a time period of the silent interval (3.5 characters long or

longer) before sending another query to an inverter after receiving a response from

the inverter.

Normal response:

• When receiving a query that contains a function code of Loopback (08h), the inverter

returns a response of the same content of the query.

• When receiving a query that contains a function code of Write in Register or Coil

(05h, 06h, 0Fh, or 10h), the inverter directly returns the query as a response.

• When receiving a query that contains a function code of Read Register or Coil (01h

or 03h), the inverter returns, as a response, the read data together with the same

slave address and function code as those of the query.

Response when an error occurs:

• When finding any error in a query (except for a transmission error), the inverter

returns an exception response without executing anything.

• You can check the error by the function code in the response. The function code of

the exception response is the sum of the function code of the query and 80h.

• The content of the error is known from the exception code.

B−19

Store New Register Data (ENTER command)

After being written in a selected holding register by the Write in Holding Register

command (06h) or in selected holding registers by the Write in Holding Registers

command (10h), new data is temporary and still outside the storage element of the

inverter. If power to the inverter is shut off, this new data is lost and the previous data

returns. The ENTER command is used to store this new data in the storage element of

the inverter. Follow the instructions below to submit the ENTER command.

Submitting an ENTER Command:

• Write any data in all memory (of a holding register at 0900h) by the Write in

Holding Register command [06h].

NOTE: The ENTER command takes much time to run. You can check its progress by

monitoring the Data Writing signal (of a coil at 001Ah).

NOTE: The service life of the storage element of the inverter is limited (to about

100,000 write operations). Frequent use of the ENTER command may shorten its

service life.

EzCOM (Peer-to-Peer communication)

• Besides standard Modbus-RTU communication (slave), WJ200 supports

Peer-to-Peer communication between multiple inverters.

• The max. number of inverter in the network is up to 247 (32 without repeater).

• One administrator inverter is necessary in the network, and the other inverters

behave as master or slave.

• Be sure to set station No.1 as an administrator inverter, which controls master

inverter according to user setting. The others will be slave inverters. An admin.

inverter is fixed, but a master inverter always turns by rotation. For this reason, an

admin. inverter can be a master or a slave.

• A master inverter is able to write data to any holding register of designated slave

inverter. The max. number of holding register is up to 5. After writing data

completed, a master inverter will be shift to the next inverter.

• The max. number of master inverter is 8.

Note 1: The command to change a master is issued by an admin. inverter automatically, which

users do not have to take care.

master inverter 01 to slave and silent interval plus communication wait time (C078) passed.

Note 3: Administrative inverter issues the next command to change a master after the data

from master inverters is sent and silent interval plus communication wait time (C078)

passed. In case the data from master inverter cannot be received within the communication

timeout (C077), then the inverter timeouts and the behaves according to the communication

error selection.

Note 4: Please set the communication timeout as it is valid (C077=0.01～99.99). If it is

disabled (C077=0.0), EzCOM function is interrupted in case the data from master inverter

was not received. In case it is interrupted, please turn on/off the power or reset (reset terminal

on/off).

Which parameters to be set?

ALL : Set all inverters in the network.

A : Set admin. inverter (address=1) only.

B : Set all inverters except admin. inverter.

M : Set master inverters configured in C098 to C099 of admin. inverter.

Note 5: Address of Administrative inverter is to be set 01 (C072=01).

Note 6: When selection of operation after communication error is set other than “ignoring errors

(C076=02)”, EzCOM function is interrupted in case of communication timeout on administrative inverter.

In this case, please power off/on or reset (on/off RES terminal) to recover.

Note 7:.If EzCOM starting trigger is set as input terminal (C100=00), be sure to configure 81 in one of

input terminals.

Note 8: If EzCOM starting trigger is set as always (C100=01), administrative inverter starts to send the

B−23

data immediately after power on. In case the establishment of the inverter to be assigned as

master of delays and fail to receive the command to change the master, the data cannot be sent

from master and administrative inverter time-outs. When C100=01 selected, please be sure to

power up the administrative inverter at last after reconfirming the establishment of inverters

other than administrative inverters.

Note 9: Although slave addresses are set in a master inverter, data is sent as broadcast address (00). If a

slave inverter receives data to another slave, it will be ignored.

Note 10:As EzCOM source and destination register, please set the number minus one from the value

listed in the table in “modbus data listing”.

Note 11: Be sure to avoid to set “08FFh(EEPROM writing)” and “0901h(EEPROM

Note 12: If above parameter is changed, the inverter power must be rebooted in order to activate new

parameters. Instead of rebooting, turning ON/OFF of reset terminal works as same.

Basic function (in case the number of data is 1 (P140=1))

• A master inverter sends data in holding register P143 of the master to a slave

inverter of address P141 and overwrites on holding register P142.

• A master inverter is changed to the next inverter, and repeats same procedure

according to setting of new master inverter.

*1 Normally, this coil is turned on when the corresponding intelligent input terminal on the control

circuit terminal block is turned on or the coil itself is set to on. In this regard, the operation of

the intelligent input terminal has priority over the operation of the coil. If disconnection of the

communication train has disabled the master system from turning off the coil, turn the

corresponding intelligent input terminal on the control circuit block on and off. This operation

turns off the coil.

*2 Communication error data is retained until an error reset command is input. (The data can be

reset during the inverter operation.)

ModBus Holding Registers

The following tables list the holding registers for the inverter interface to the network.

The table legend is given below.

• Function Code - The inverter’s reference code for the parameter or function (same as

inverter keypad display)

• Name - The standard functional name of the parameter or function for the inverter

• R/W - The read-only(R) or read-write access(R/W) permitted to the data in the

inverter

• Description - How the parameter or setting works (same as Chapter 3 description).

• Reg. - The network

for the value. Some values have a

high-byte and low-byte address.

• Range - The numerical range for the network value that is sent and/or received

TIP: The network values are binary integers. Since these values cannot have an

embedded decimal point, for many parameters it represents the actual value (in

engineering units) multiplied by a factor of 10 or 100. Network communications must

use the listed range for network data. The inverter automatically divides received

values by the appropriate factor in order to establish the decimal point for internal use.

Likewise, the network host computer must apply the same factor when it needs to work

in engineering units. However, when sending data to the inverter, the network host

computer must scale values to the integer range listed for network communications.

• Resolution - This is the quantity represented by the LSB of the network value, in

engineering units. When the network data range is greater than the inverter’s

internal data range, this 1-bit resolution will be fractional.

Introduction

This appendix lists the user-programmable parameters for the WJ200 series inverters

and the default values for European and U.S. product types. The right-most column of

the tables is blank, so you can record values you have changed from the default. This

involves just a few parameters for most applications. This appendix presents the

parameters in a format oriented toward the keypad on the inverter.

Parameter Settings for Keypad Entry

WJ200 series inverters provide many functions and parameters that can be configured

by the user. We recommend that you record all parameters that have been edited, in

order to help in troubleshooting or recovery from a loss of parameter data.

CE-EMC Installation Guidelines

You are required to satisfy the EMC directive (2004/108/EC) when using an WJ200 inverter

in an EU country.

To satisfy the EMC directive and to comply with standard, you need to use a dedicated EMC

filter suitable for each model, and follow the guidelines in this section. Following table shows

the compliance condition for reference.

WJ200-150HFE

WJ200-110L and 150H needs to be installed in a metal cabinet and add ferrite core

at the input cable to meet category C1. Unless otherwise category C2.

Important notes

1. Input choke or other equipment is required if necessary to comply with EMC

directive from the harmonic distortion point of view (IEC 61000-3-2 and 4).

2. If the motor cable length exceeds 20m, use output choke to avoid unexpected

problem due to the leakage current from the motor cable (such as malfunction of

the thermal relay, vibration of the motor, etc..).

D−3

3. As user you must ensure that the HF (high frequency) impedance between

adjustable frequency inverter, filter, and ground is as small as possible.

• Ensure that the connections are metallic and have the largest possible contact

areas (zinc-plated mounting plates).

4. Avoid conductor loops that act like antennas, especially loops that encompass large

areas.

• Avoid unnecessary conductor loops.

• Avoid parallel arrangement of low-level signal wiring and power-carrying or

noise-prone conductors.

5. Use shielded wiring for the motor cable and all analog and digital control lines.

• Allow the effective shield area of these lines to remain as large as possible; i.e.,

do not strip away the shield (screen) further away from the cable end than

absolutely necessary.

• With integrated systems (for example, when the adjustable frequency inverter

is communicating with some type of supervisory controller or host computer in

the same control cabinet and they are connected at the same ground +

PE-potential), connect the shields of the control lines to ground + PE (protective

earth) at both ends. With distributed systems (for example the communicating

supervisory controller or host computer is not in the same control cabinet and

there is a distance between the systems), we recommend connecting the shield

of the control lines only at the end connecting to the adjustable frequency

inverter. If possible, route the other end of the control lines directly to the cable

entry section of the supervisory controller or host computer. The shield

conductor of the motor cables always must connected to ground + PE at both

ends.

• To achieve a large area contact between shield and ground + PE-potential, use

a PG screw with a metallic shell, or use a metallic mounting clip.

• Use only cable with braided, tinned copper mesh shield (type “CY”) with 85%

coverage.

• The shielding continuity should not be broken at any point in the cable. If the

use of reactors, contactors, terminals, or safety switches in the motor output is

necessary, the unshielded section should be kept as short as possible.

• Some motors have a rubber gasket between terminal box and motor housing.

Very often, the terminal boxes, and particularly the threads for the metal PG

screw connections, are painted. Make sure there is always a good metallic

connection between the shielding of the motor cable, the metal PG screw

connection, the terminal box, and the motor housing. If necessary, carefully

remove paint between conducting surfaces.

6. Take measures to minimize interference that is frequently coupled in through

installation cables.

• Separate interfering cables with 0.25m minimum from cables susceptible to

interference. A particularly critical point is laying parallel cables over longer

distances. If two cables intersect (one crosses over the other), the interference is

smallest if they intersect at an angle of 90°. Cables susceptible to interference

should therefore only intersect motor cables, intermediate circuit cables, or the

wiring of a rheostat at right angles and never be laid parallel to them over

longer distances.

7. Minimize the distance between an interference source and an interference sink

(interference- threatened device), thereby decreasing the effect of the emitted

interference on the interference sink.

• You should use only interference-free devices and maintain a minimum

distance of 0.25 m from the adjustable frequency inverter.

D−4

8. Follow safety measures in the filter installation.

• If using external EMC filter, ensure that the ground terminal (PE) of the filter

is properly connected to the ground terminal of the adjustable frequency

inverter. An HF ground connection via metal contact between the housings of

the filter and the adjustable frequency inverter, or solely via cable shield, is not

permitted as a protective conductor connection. The filter must be solidly and

permanently connected with the ground potential so as to preclude the danger

of electric shock upon touching the filter if a fault occurs.

To achieve a protective ground connection for the filter:

• Ground the filter with a conductor of at least 10 mm

cross-sectional area.

• Connect a second grounding conductor, using a separate grounding terminal

parallel to the protective conductor. (The cross section of each single protective

conductor terminal must be sized for the required nominal load.)

D−5

Installation for WJ200 series (example of SFE models)

Model LFx (3-ph. 200V class) and HFx (3-ph. 400V class) are the same concept for the

installation.

*) Both earth portions of the shielded cable must be connected to the earth point by

cable clamps.

Input choke or equipment to reduce harmonic current is necessary for CE marking

(IEC 61000-3-2 and IEC61000-3-4) from the harmonic current point of view, even

conducted emission and radiated emission passed without the input choke.

Hitachi EMC Recommendations

WARNING: This equipment should be installed, adjusted, and serviced by qualified

personal familiar with construction and operation of the equipment and the hazards

involved. Failure to observe this precaution could result in bodily injury.

Use the following checklist to ensure the inverter is within proper operating ranges

and conditions.

1. The power supply to WJ200 inverters must meet these specifications:

• Voltage fluctuation ±10% or less

• Voltage imbalance ±3% or less

• Frequency variation ±4% or less

• Voltage distortion THD = 10% or less

2. Installation measure:

• Use a filter designed for WJ200 inverter. Refer to the instruction of the

applicable external EMC filter.

3. Wiring:

• Shielded wire (screened cable) is required for motor wiring, and the length must

be 20 meter or less.

• If the motor cable length exceeds the value shown above, use output choke to

avoid unexpected problem due to the leakage current from the motor cable.

• The carrier frequency setting must be 2 kHz to satisfy EMC requirements.

• Separate the power input and motor wiring from the signal/process circuit

wiring.

4. Environmental conditions—when using a filter, follow these guidelines:

• Ambient temperature: –10 to 50 °C (Derating is required when the ambient

temperature exceeds 40 °C)

• Humidity: 20 to 90% RH (non-condensing)

• Vibration: 5.9 m/sec2 (0.6 G) 10 ~ 55Hz

• Location: 1000 meters or less altitude, indoors (no corrosive gas or dust)

Introduction

The Gate Suppress function can be utilized to perform a safe stop according to the

EN60204-1, stop category 0 (Uncontrolled stop by power removal). It is designed to

meet the requirements of the ISO13849-1, PL=d only in a system in which EDM signal

is monitored by an “external device monitor”. (Otherwise PL of drive downgraded to

PL=c.)

How it works

Removing the currents from both terminals GS1 and GS2 disables the drive output, i.e.

the power supply to the motor is cut by stopping the switching of the output transistors

in a safe way. EDM output is activated when GS1 and GS2 are given to the drive.

Always use both inputs to disable the drive. If for any reason only one channel is

opened, the drive output is stopped but the EDM output is not activated. In this case

the Safe Disable input wiring must be checked.

Installation

When the Gate Suppress function is utilized, connect the drive to a safety certified

interrupting device utilizing EDM output signal to reconfirm both safety inputs GS1

and GS2. Follow the wiring instructions in the user manual chapter 3.

In combination with the safety device complying with the class complying PL=d,

PL=d of the inverter is to be achieved.

Periodical check

Since the drive stops even one of the GS1 or GS2 is interrupted, it is to be reconfirmed

that there is not faiure in the path of GS1 and GS2 periodically. Period of this

maintenance is once per year, and the method to make sure GS1 and GS2 in

combination with EDM signal is as described below.

Precautions

1. To assure, that the Safe Disable function appropriately fulfills the safety

requirements of the application, a throughout risk assessment for the whole safety

system has to be carried out.

2. If EDM signal is not utilized in the system as a reconfirmation of redundancy

between GS1 and GS2, PL of drive is downgraded to PL=c.

3. The Safe Disable function does not cut the power supply to the drive and does not

provide electrical isolation. Before any installation or maintenance work is done,

the drives power supply must be switched off.

4. The wiring distance for the Safe Disable inputs should be shorter than 30 m.

5. The time from opening the Safe Disable input until the drive output is switched off

is less than 10 ms.

6. When two or more inverters are connected to common GS1 and GS2 wiring, please

be sure to put the diode as instructed in page 4-14, otherwise the drive may start to

work even in the safety mode.
