!

interruption to avoid an unexpected restart (if operation is set to be continued in the
processing selection function after momentary power interruption is reset). Doing so
may result in injury.

WARNING Provide a separate emergency stop switch because the STOP Key on the Operator

!

is valid only when function settings are performed. Not doing so may result in injury.

WARNING Be sure to confirm that the RUN signal is turned OFF before turning ON the power

!

supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so
while the RUN signal is turned ON may result in injury.

Caution Be sure to confirm permissible ranges of motors and machines before operation be-

!

cause the Inverter speed can be easily changed from low to high. Not doing so may
result in damage to the product.

Warnings for UL/cUL Marking

• Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON.

• The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent

electrical shock, disconnect all power before servicing the Inverter. Then wait at least one minute after
the power supply is disconnected and all indicators are OFF.

• Do not perform a withstand voltage test on any part of the Inverter. This electronic equipment uses
semiconductors and is vulnerable to high voltage.

• Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never
touch the printed control board (PCB) while the power supply is turned ON.

• The Inverter is not suitable for use on a circuit capable of delivering more than 5,000 RMS symmetrical
amperes, 250 volts maximum (100-V-class Units).

• Take measures against overcurrent, overload, and overheating by using the Motor Protection Set­tings.

CAUTION

Use 75°C copper wires or equivalent.
Low voltage wires shall be wired with Class I Wiring.

H Motor Protection Settings

Rated Motor Current (n32)

• Set the rated motor current (n32) in order to prevent the motor from burning due to overloading.

• Check the rated current on the motor nameplate and set the parameter.

• This parameter is used for the electronic thermal function for motor overload detection (OL1). By set-

ting the correct parameter, the overloaded motor will be protected from burning.

H Installation Direction and Dimensions

• Install the Inverter under the following conditions.

Ambient temperature for operation (panel-mounting): –10°C to 50°C

Humidity: 95% or less (no condensation)

• Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally en­closed panel that is completely protected from floating dust.

• When installing or operating the Inverter, always take special care so that metal powder, oil, water, or
other foreign matter does not get into the Inverter.

• Do not install the Inverter on inflammable material such as wood.

H Direction

• Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward.

H Dimensions

• When installing the Inverter, always provide the following clearances to allow normal heat dissipation
from the Inverter.

W = 30 mm min.

Inverter

100 mm min. Air

SideInverter Inverter

100 mm min. Air

H Ambient Temperature Control

• To enhance operation reliability, the Inverter should be installed in an environment free from extreme
temperature changes.

• If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner
to maintain the internal air temperature below 50°C.
The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air
temperature as low as possible.

• The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temper­ature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment
and wires are easily influenced by heat.

H Protecting Inverter from Foreign Matter during Installation

• Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will
be affected, causing the Inverter to overheat.

2-1-2 Accepting Operation Commands While Changing

Parameters

With the default settings, the Inverter will not accept operation commands when param­eter settings are being changed. This functions as a safety measure to prevent the motor
from rotating if the operation command is mistakenly set to ON when changing parame­ters.
Depending on the operating conditions, however, the user may want to have operation
commands accepted even while parameters are being changed. In that case, change
the following settings.

H Using the Indicators to Determine When Operation Commands Can Be

Accepted

The indicators on the Digital Operator can be used to determine if operation commands will be accepted
or not while changing parameters.

Green: Operation commands will be accepted if the indicator lights green.

Red: Operation commands will not be accepted after the Inverter stops if an indicator lights red.

Therefore, if the indicator lights red when changing parameters or when switching between local and
remote operation, operation will continue, but once the Inverter stops, the Inverter will not operate even
if the operation command is set to ON again.

The FREF indicator will light when the power supply is turned ON.

FOUT Green Output Frequency Monitor
IOUT Green Output Current Monitor
MNTR Green Multi–function Monitor

LO/RE Red Local/Remote Selection

Note Perform the settings given in the following description to have operation commands accepted

while the red indicator is lit (i.e., while changing parameters or switching between local and re­mote.)

Set n01 (Parameter write–prohibit selection/parameter initialization) to 5.

S The default value for n01 is 1.

S Operation commands will not be accepted when n01 itself is being changed.

S Some parameters cannot be changed during operation. Those parameters cannot be changed

2-2 Copying and Verifying Parameters

The 3G3IV-PJVOP140 and 3G3IV-PJOP146 Digital Operators contain an EEPROM.
All Inverter parameter settings, the Inverter capacity, and the software number are re­corded in this EEPROM. The EEPROM can be used to copy parameter settings to other
Inverters.
Parameter settings can be copied between Inverters with the same power supply speci­fications, but some of the parameter settings are not copied.

manufacturer the thermal time
constant and set the parame­ter with some margin. In other
words, set the value slightly
shorter than the thermal time
constant.

Note To detect motor overloading

quicker, reduce the set value,
provided that it does not cause
any application problems.

Used to operate the Cooling Fan of
the Inverter while the Inverter is
turned on or only while the Inverter is
in operation.

4-1-1 Fault Detection (Fatal Error)

The Inverter will detect the following faults if the Inverter or motor burns or the internal
circuitry of the Inverter malfunctions. When the Inverter detects a fault, the fault code will
be displayed on the Digital Operator, the fault contact output will operate, and the
Inverter output will be shut off causing the motor to coast to a stop. The stopping method
can be selected for some faults, and the selected stopping method will be used with
these faults. If a fault has occurred, refer to the following table to identify and correct the
cause of the fault. Use one of the following methods to reset the fault after restarting the
Inverter. If the operation command is being input, however, the reset signal will be ig­nored. Therefore, be sure to reset the fault with the operation command turned off.
S Turn on the fault reset signal. A multi-function input (n36 to n39) must be set to 5 (Fault

Communications time-over (CE)

Normal RS-422A/485 communications
were not established within 2 s. The
Inverter will detect this error if n68
(RS-422A/485 communications
time-over detection selection) is set to
0, 1, or 2.

Operation error (OPj)

(Parameter setting error)

• A short-circuit, ground fault, or disconnection has
occurred on the communications line.

→ Check and correct the line.

• The termination resistance setting is incorrect.

→ Set the termination resistance of only the

Inverter located at each end of the network to
ON.

• Noise influence.

→ Do not wire the communications line along

with power lines in the same conduit.

→ Use the twisted-pair shielded wire for the

communications line, and ground it at the
Master.

• Master’s program error.

→ Check and correct the program so that

communications will be performed more than
once every 2-s period.

• Communications circuit damage.

→ If the same error is detected as a result of a

self-diagnostic test, change the Inverter.

• The values in n36 through n39 for multi-function
inputs 1 through 4 have been duplicated.

→ Check and correct the values.

• The V/f pattern settings do not satisfy the follow-

ing condition.
n14 x n12 t n11x n09

→ Check and correct the set value.

• The rated motor current set in n32 exceeds

150% of the rated output current of the Inverter.

→ Check and correct the value.

• The frequency reference upper limit set in n30

and the frequency reference lower limit set in n31
do not satisfy the following condition.
n30 y n31

→ Check and correct the set values.

• The jump frequencies set n49, n50 do not satisfy

the following condition.
n49 y n50

→ Check and correct the set values.

4-2 Inspection and Maintenance

H Daily Inspection

Check the following items while the system is operating.

• No abnormal noise or vibration in the motor

• No abnormal heat generation

• Output current monitor display is not a higher value than normal

• Cooling fan installed in Inverter is operating normally (models with fans only)

H Periodic Inspection

Check the following items when performing periodic maintenance.

Always wait at least one minute after the power supply has been turned OFF and all the LED indicators
have turned OFF before performing maintenance. Touching the terminals immediately after the power
is turned OFF may result in electric shock.

• No looseness in terminal screws

• No electroconductive dust or oil mist attached to terminal block or the Inverter’s internal parts

• No looseness in Inverter mounting screws

• No accumulation of dirt or dust on cooling fin (heat sink)

• No dust accumulated in the ventilation holes

• No abnormality in external appearance

• Cooling fan in control panel is operating normally

(Check that there is no abnormal noise or vibration, and that the total ON time has not exceeded the
specified value.)

H Periodic Maintenance of Components

The Inverter is constructed from many components, the normal operation of which is required for the
essential functionality of the Inverter. Maintenance is required for some of the electronic components
depending on the operating conditions. To enable the Inverter to operate normally for a long time, peri­odic inspection and component replacement must be performed to suit the service life of these compo­nents.

(Source: “Instructions for Periodic Inspection of General Purpose Inverter” (JEMA))

The guidelines for periodic inspection depend on the Inverter’s installation environment and operating
conditions.

The maintenance periods for the Inverter are listed below. Use this to determine when periodic mainte­nance is required.

The guidelines for periodic maintenance are as follows:

• Cooling fan: 2 to 3 years

• Electrolytic capacitor: 10 years

• Fuse: 10 years

These guidelines are applicable for an operating environment in which the ambient temperature is
40°C, the load rate is 80%, the operating time is 8 hours per day, and the product is installed according to
the instructions in the manual.

4-10

Maintenance Operations Chapter 4

To extend the maintenance period, it is recommended to lower the ambient temperature and shorten
the ON time as much as possible.
