GRJ
0008 Input phase failure
• A phase failure occurred in the
input line of the main circuit.
• The inverter may trip because of
GRJ if switching between
acceleration and deceleration is
done in succession at intervals
of less than 1 second.
• Check the main circuit input line
for phase failure.
• Enable H (input phase
failure detection). Set the
H parameter to 0.
QJ 0010 Overheat
• The cooling fan does not rotate.
• The ambient temperature is too
high.
• The vent is blocked up.
• A heat generating device is
installed close to the inverter.
• The thermistor in the unit is
broken.
• Restart the operation by
resetting the inverter after it has
cooled down enough.
• The fan requires replacement if
it does not rotate during
operation.
• Secure sufficient space around
the inverter.
• Do not place any heat-
generating device near the
inverter.
• Make a service call.
＊WR
001E Undervoltage trip
(main circuit)
• The input voltage (in the main
circuit) is too low.
• Check the input voltage.
• Enable H (undervoltage
trip selection).
• To cope with a momentary stop
due to undervoltage, enable
H (ride-through control)
and H (auto-restart).
GH 0022 Ground fault trip
Arm overcurrent
• A ground fault occurs in the
output cable or the motor.
• A main circuit element is
defective.
• Check the cable and the motor
for ground faults.
• Make a service call.
G
0011 Emergency stop
• During automatic operation or
remote operation, a stop
command is entered from the
operation panel or a remote
input device.
• Reset the inverter.
GTT 0015 Main unit RAM fault
• The control RAM is defective. • Make a service call.
GTT 0016 Main unit ROM fault
• The control ROM is defective. • Make a service call.
GTT 0017 CPU fault trip
• The control CPU is defective. • Make a service call.
GTT
0018 Remote control
error
• An error arises during remote
operation.
• Check the remote control
device, cables, etc.
GTT
001A Current defector
fault
•The current detector is defective. • Make a service call.
GGR
0012 EEPROM fault 1
• A data writing error occurs. • Turn off the inverter, then turn it
on again. If it does not recover
from the error, make a service
call.
GGR 0013 EEPROM fault 2
• Power supply is cut off during
V[R operation and data
writing is aborted.
• Turn the power off temporarily
and turn it back on, and then try
V[R operation again.
GGR
0014 EEPROM fault 3
• A data writing error occurs. • Turn off the inverter, then turn it
on again. If it does not recover
from the error, make a service
call.

G
0032 Break in analog
signal cable
• The signal input via VI/S3 is
below the analog signal
detection level set with H.
• Check the cables for breaks
and change the setting of
H if no breaks are found.
