NOTE : POLLUTION DEGREE 2

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

The inverter must be used in environment of the degree 2.
Typical constructions that reduce the possibility of conductive pollution are;

1) The use of an un-ventilated enclosure

2) The use of a filtered ventilated enclosure when the ventilation is fan forced that is,
ventilation is accomplished by one or more blowers within the enclosure that provide a
positive intake and exhaust.

NOTE : ENCLOSURE SIZE FOR 75 kW TO 110 kW

The inverter, 75kW to 110kW must be installed into an enclosure with dimmensions no
less than 183cm (72 in) by 183cm (72 in) by 60cm (24 in).

NOTE : ENCLOSURE SIZE FOR 132 kW AND BIGGER

The inverters, 132kW and bigger, are complied as recognizedcomponents.
Therse devices are intended for use in an overall ecclosure with an internal ambient of
40 degree C for variable torque rating or 50 degree C for constant torque rating maximum.
End product temperature testing should be conducted to verify sufficient forced air ventilation
is provided to maintain this ambient in room ambient of 10-40 degree C.
Based upon component level testing , end product temperature testing may be conducted at
any convenient room ambient in the rangeof 20-40 dwgree C, unless the room ambient in the
intended application exceeds 40degree C, in which case testing should be conducted at the
elevated ambient.
Enclosure internal ambient temperature should be measured above the drive on to the upper
left or right side. Temperature measurments on the drive itself should not be necessary.

NOTE : SET OF MOTOR CAPACITY AND POLES (A1, A2)

When data does not match a capacity of connected motor , it may cause unstaible motor
operation. Set proper motor capacity (kW) and motor poles even under V/F control mode.

there is a possibility that such an occurrence may harm humans, then install an
electromagnetic contactor (Mgo) on the power supply side, so that the circuit does not
allow automatic restarting after the power supply recovers. If the optional remote
operator is used and the retry function has been selected, this will also cause automatic
restarting when an operation instruction has been input, so please be careful.

* MOTOR TERMINAL SURGE VOLTAGE SUPPRESSION FILTER

(FOR THE 400 V CLASS)

In a system using an inverter of the voltage control PWM system, a surge voltage
caused by the cable constants such as the cable length (especially when the distance
between the motor and inverter is 10 m or more) and cabling method may occur at the
motor terminal.

A dedicated filter of the 400 V class for suppressing this surge voltage is available,
Please order one.

* PROTECTION AGAINST NOISE INTERFERENCE FROM INVERTER

The inverter uses many semiconductor switching elements such as transistors and
IGBTs. Thus, a radio set or measuring instrument located near the inverter is
susceptible to noise interference.

To protect the instruments from erroneous operation due to noise interference, they
should be installed well apart from the inverter. It is also effective to shield the whole
inverter structure.

Addition of an EMI filter on the input side of the inverter also reduces the effect of
noise from commercial power line on external devices.

Note that external dispersion of noise from the power line can be minimized by
connecting an EMI filter on the primary side of inverter.

NOTE : ENCLOSURE SIZE FOR 75 kW to 110kW

The inverters, 75kW to 110kW must be installed into an enclosure with dimmensions no
less than 183cm (72 in) by 183cm (72 in) by 60cm (24 in).

NOTE : ENCLOSURE SIZE FOR 132 kW AND BIGGER

The inverters, 132kW and bigger, are complied as recognizedcomponents.
Therse devices are intended for use in an overall ecclosure with an internal ambient of
40 degree C for variable torque rating or 50 degree C for constant torque rating maximum.
End product temperature testing should be conducted to verify sufficient forced air ventilation
is provided to maintain this ambient in room ambient of 10-40 degree C.
Based upon component level testing , end product temperature testing may be conducted at
any convenient room ambient in the rangeof 20-40 dwgree C, unless the room ambient in the
intended application exceeds 40degree C, in which case testing should be conducted at the
elevated ambient.
Enclosure internal ambient temperature should be measured above the drive on to the upper
left or right side. Temperature measurments on the drive itself should not be necessary.

The higher the ambient temperature inside the inverter, the shorter its life will be. If

a heat generating unit is used near the inverter, try to keep it as far away as possible.
Also, when installing the inverter in a box, be sure to carefully consider ventilation
and the dimensions.

Otherwise, there is a danger of fire.

Be sure to install an earth leakage breaker.

* The ground fault protection is designed to detect current flowing to the ground upon

power on. This function is to protect the inverter,not people. Install the earth leakage
breaker to protect against the ground fault on wires between the inverter and the motor.
(Use a breaker that is very sensitive to high frequency current so as not to cause
malfunction.)

* Be sure to set the fuse(s) (the same phase as the main power supply)

in the operation circuit.
Otherwise, there is a danger of fire.

As for motor leads, earth leakage breakers and electromagnetic contactors, be sure to
use the equivalent ones with the specified capacity (rated).
Otherwise, there is a danger of fire.

is a rapid change in the power supply.
It also improves the power factor.

Using the inverter may cause noise on the peripheral
equipment through the power lines.
This part reduces noise.

This part reduces common noise generated between
the power supply and the ground, as well as normal noise.
Put it in the primary side of inverter.

This part is used for applications that needs to increase
the brake torque of the inverter or to frequently turn on
and off and to run high inertia load.

This part reduces noise generated at the output of
the inverter.
(It is possible to use for both input and output.)

Running motors with the inverter generates vibration
greater than that with commercial power supply.
This part installed between the inverter and motor reduces
torque ripple.
When the cable length between the inverter and motor is
long, a countermeasure for a malfunction of the termal
relay is taken.

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

6.1 Before Starting Operation

Prior to the test run, check the following.

WARNING

* Be sure to turn on the input power supply after mounting the surface cover. While

being energized, be sure not to remove the cover.
Otherwise, there is a danger of electric shock.

* Be sure not to operate the switches with wet hands.

Otherwise, there is a danger of electric shock.

* While the inverter is energized, be sure not to touch the inverter terminals even during

stoppage.
Otherwise, there is a danger of electric shock.

* If the re-try mode is selected, it may suddenly restart during the trip stop. Be sure not

to approach the machine. (Be sure to design the machine so that personnel safety will
be secured even if it restarts.)
Otherwise, there is a danger of injury.

* Even if the power supply is cut for a short period of time, it may restart operation after

the power supply is recovered if the operation command is given. If it may incur
danger to personnel, be sure to make a circuit so that it will not restart after power
recovery.
Otherwise, there is a danger of injury.

* The Stop Key is effective only when the function is set. Be sure to prepare the Key

separately from the emergency stop.
Otherwise, there is a danger of injury.

* After the operation command is given, if the alarm reset is conducted, it will restart

suddenly. Be sure to set the alarm reset after checking the operation command is off.
Otherwise, there is a danger of injury.

* Be sure not to touch the inside of the energized inverter or to put a bar into it.

Otherwise, there is a danger of electric shock and/or fire.

6-1

CAUTION

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

* Radiating fin and discharging resistor will have high temperature. Be sure not to touch

them.
Otherwise, there is a danger of getting burned.

* Low to high speed operation of the inverter can be easily set. Be sure to operate it

after checking the tolerance of the motor and machine.
Otherwise, there is a danger of injury.

* If a motor is operated at a frequency higher than 60Hz, be sure to check the speeds of

the motor and the machine with each manufacturer, and after getting their consent,
operate them.
Otherwise, there is a danger of machine breakage.

Note:

(1) Make sure that the power lines (input power supply R(L1), S(L2) and T(L3), and output

terminals, U(T1), V(T2) and W(T3) are connected correctly.

(2) Make sure that there are no mistakes in the signal line connections.

(3) Make sure that the inverter case ( ) is grounded.

(4) Make sure that terminals other than those specified are not grounded.

(5) Make sure that the inverter is installed vertically on a wall, and a nonflammable material

such as a steel plate is used as a mounting surface.

(6) Make sure that there are no short-circuits caused by stray pieces of wire, solderless termi-

nals or other objects left from wiring work. Also, make sure that no tools have been left
behind.

(7) Make sure that the output wires are not short-circuited or grounded.

(8) Make sure that there are no loose screws or terminals.

(9) Make sure that the maximum frequency setting matches the machine specifications.

Be sure to refer to page 10-2 when conducting insulation resistance and withstand
voltage tests. Never test terminals other than those which are indicated.

6-2

6.2 Test Run

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

Check the following before and during the test run.
Otherwise, there is a danger of machine breakage.

• Was the direction of the motor correct?

• Was the inverter tripped during acceleration or deceleration?

• Were the SPEED (rpm) and frequency meter correct?

• Were there any abnormal motor vibrations or noise?

When overcurrent tripping or overvoltage tripping occurs during the test run, increase
the acceleration time or deceleration time.

• Saving the alarm signal
When an alarm signal is outputted, the alarm signal data is stored even if the input power is

turned off and the contents can be checked by turning the power on once again. However,
when the input power is turned off, the inverter control power is also turned off. As a
result, when the power is turned on next, the alarm contact output is reset (deleted). There­fore, when saving the alarm contact output, let the external sequence receive and save it
and then turn off the inverter input power.

• When the alarm contact output is set ON during normal run, a time delay occurs until the
contact is closed when the power is turned on. Therefore, when using the alarm contact
output, set a time delay of about 2 seconds when the power is turned on.

When returning the equipment to the initial state set at factory before shipment for some reason,
follow the following procedure.

1) Allocate STN (set value ) to one of the input intelligent terminals. (Use to
in the extension function mode to set the intelligent terminals.)

(However, cannot be used since resetting RS is initially set.)

2) Short-circuit the STN terminal and P24 (CM1*), then turn power off and on. (When the power is
turned off, do not turn it on again until the CHARGE lamp of the logic PCB goes off.)

3) Keep the STN terminal open for more than 6 seconds. (When keying, resetting, or turning power
off is performed within 6 seconds, the equipment may not be initialized.)

4) Turn the power off after more than 6 seconds. (When the power is turned off within 6 seconds,
the equipment may not be initialized.)

8. PROTECTION FUNCTIONS

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

The J300 series inverters are equipped with protection functions against overcurrent,
overvoltage, and undervoltage which protect the inverter. If the protection functions are
engaged, the output is shut down, motor runs free and holds that condition until it is reset.

Undervoltage
protection

CT error Abnormality on built-in CT and the output of the inverter is cut off.

A currrent due to the alternating current CT between the power module
and output terminal {U(T1), V(T2), W(T3)} is detected.
When the motor is restricted or decelerated suddenly, a large current
flows through the inverter and causes a fault. Therefore, when an
abnormal current is detected by the alternating current CT and it exceeds
a specified value, the output is cut off. (An abnormal current is also
detected in the power module. Refer to , , , and .)

When a motor overload is detected by the electronic thermal function, the output
of the inverter is cut off.

When the braking time exceeds the satting by braking duty factor, an
overvoltage the output of the inverter is cut off.

When the converter voltage exceeds a certain level due to regenerative energy from
the motor, this protection function engages, and the output of inverter is cut off.

When the memory built in has problems due to noise or excessive temperature rise,
this protective function engages, and the output of inverter is cut off.

A decrease of the input voltage of an inverter results in improper function of the
control circuit. It also generates motor heat and causes low torque. Output is cut off
when the input voltage goes down to less than 150-160V/300-320V(200/400Vclass).

Malfunction or abnormality on built-in CPU and the output of the inverter is cut

An abnormality signal from external equipment cuts off the output of the inverter.
(When external trip function is selected)

It indicates an error when power is turned on while the inverter is being run.
(When USP function is selected)

The inverter is protected by detection of ground faults between the inverter output
and the motor upon power on. There may be the possibility of power module failure.

When the input voltage is higher than the specified value, it is detected 100 seconds
after power is turned on and the output is cut off. However, when a voltage higher
than approx. 250 to 270 V (200V class),
500 to 530 V (400 V class) is inputted, it is higher than the rated value of the part
in use, so that the part may not be protected and damaged.

When an instantaneous power failure for more than 15 ms occurs, the output is cut
off. When the instantaneous power failure time is long, the fault signal is released.
Note that when restart is selected, the equipment restarts when the running
command remains.

It is displayed when the reset signal is kept supplied or an error occurs between the digital operator

Power module
protection

The detector which is built in the power module operates.
When the output side of the inverter is shorted or the motor is
restricted, a large current flows through the inverter and causes a
fault. Therefore, when a current in the power module or an
abnormal temperature of the main device is detected and it
exceeds a specified value, the output is cut off.

A trip can be cleared by pressing the RESET key or shorting the reset terminal RS-CM1 assigned
as a control circuit terminal. Resetting the power supply cannot clear a trip. (To reset the power supply is
to turn power off and turn it on again after the CHARGE lamp at the upper right corner of the control PC
board goes off.) Check again whether the set data is correct.
Power OFF during motor deceleration may cause an input phase failure error.
The instantaneous ride-thru period of 15ms may be shortend depending on the power supply voltage or load.

10. MAINTENANCE AND INSPECTION

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

10.1 Maintenance and Inspection Precautions

WARNING

* Be sure to turn off the power supply during maintenance and inspection.
* After the power supply has been turned off, you must always wait 10 minutes so that

DC bus capacitors can discharge then start maintenance and inspection after the
CHARGE lamp on the printed-circuit board has gone out. (Immediately after the lamp
has gone out, there will be a residual voltage of about 50 V DC in the DC bus
intermediate circuit.)
Perform the work after the CHARGE lamp has stopped flickering.

* Make sure that only qualified persons will perform maintenance, inspection and part

replacement. (Before starting the work, remove metallic objects from your person
(wristwatch, bracelet, etc.)
(Be sure to use tools protected with insulation.)
Otherwise, there is a danger of electric shock and/or injury.

CAUTION

* When removing connectors, never pull the wires. (Wires for cooling fan and thermal

relay)
Otherwise, there is a danger of fire due to wire breakage and/or injury.

• General precautions

Always keep the unit clean so that dust or other foreign matter does not enter the inverter.
Take special care in regard to breaking lines and connection mistakes. Firmly connect
terminals and connectors. Keep electronic equipment away from moisture and oil. Dust,
steel filings and other foreign matter can damage insulation, causing unexpected accidents,
so take special care.

10.2 Inspection Items

(1) Daily inspection
(2) Periodic inspection (Approximately once a year) See 10-3.
(3) Insulation resistance tests, withstand voltage tests

10-1

Conduct these tests by short-circuiting the terminals as shown below, and by following the

Applied

conditions described.

• In regard to insulation resistance tests, measure the terminals below and the grounding at
500 VDC, and make sure that 5 Megohms or greater is indicated.

• Do not perform the withstand voltage test. When it should be done,
in regard to withstand voltage tests, supply the terminals below and the grounding with
1500 VAC (200 V class), 2000 VAC (400 V class) for one minute, and make sure that
there are no abnormalities.

• Do not conduct insulation resistance tests and withstand voltage tests for terminals other
than those indicated below.

• Increase or decrease the applied voltage for the withstand voltage test slowly and turn the
equipment 0 V again.

NOTE 1: If the inverter is used under high temperature and heavy load conditions, its operat-

ing life will be significantly reduced.

NOTE 2: If the inverter has been stored for three years or more, apply the following condi-

tions.

1) Apply 80% of the rated voltage of the capacitor for 1 hour at normal tempera­ture.

2) Increase the voltage to 90% and apply it for 1 hour.

3) Apply the rated voltage for 5 hours.

NOTE 3: Precautions in handling printed-circuit boards.

When maintenance and inspection of printed-circuit boards is necessary, be sure to
follow the precautions below.

• Prevent damage caused by static electricity. The IGBT of the inverter module,

the MCUs and ICs on a printed-circuit board can be destroyed by static electric­ity, so be sure to ground work benches, soldering irons, and yourself before
working on a printed-circuit board.

The applicable motor is a Hitachi standard four-pole motor. When using another motor,
make sure that the rated motor current does not exceed the rated inverter current.
Applicable motor rating at variable torque is valid with the condition that output current
does not exceed the rating at variable torque.
When a V/F pattern (VP1, VP2, or VP3) for variable torque is selected (
for the digital operator or F04 for the remote operator), the setting data are automatically
changed by the inverter.
CT: Constant torque.
VT: Variable torque.
