Error
code
Description Possible causes Remedies
GGR EEPROM error
•A data writing error occurs. •Turn off the inverter, then turn it again. If it does not
recover from the error, make a service call.
GGR Initial read error •Some internal data is corrupted. •Make a service call.
GGR Initial read error •Some internal data is corrupted. •Make a service call.
GH
GH
Ground fault
•A current leaked from an output
cable or the motor to ground.
•Check the cable and the motor for ground faults.
*
GRJ
Output phase
failure
•A phase failure occurred in the
output line of the main circuit.
•Check the main circuit output line, motor, etc. for
phase failure.
•Select output phase failure detection parameter H.
*
GRJ
Input phase
failure
•A phase failure occurred in the
input line of the main circuit.
•Check the main circuit input line for phase failure.
GTT Main unit RAM
fault
•The control RAM is defective. •Make a service call.
GTT Main unit ROM
fault
•The control ROM is defective. •Make a service call.
GTT CPU fault •The control CPU is defective. •Make a service call.
GTT Communication
time-out error
• A normal communication was not
possible for the time or longer set
by H.
•Check the remote control device, cables, etc.
GTT Gate array fault •Main gate array is defective. •Make a service call.
GTT Output current
detector error
•The main output current detector is
defective.
•Make a service call.
GTT Optional unit
fault
•An optional device has failed.
(such as a communication device
[add-on option])
•Check the connection of optional board(s).
•Refer to instructions of options concerned
specified in Section 6.41.
GVP Tuning error
•The capacity of the motor
connected is 2 notches or more
smaller than the inverter capacity.
•The motor connected is not a
three-phase inductive motor.
•Tuning is performed while the
motor is running.
•Make sure that a motor is connected.
•Make sure that the motor is at standstill.
•Perform auto-tuning 1 again and if the error
persists, perform tuning manually.
GVP
H tuning
error
•Tuning required to boost torque as
specified with H cannot be
performed.
•The capacity of the motor
connected is 2 notches or more
smaller than the inverter capacity.
•The motor connected is not a
three-phase inductive motor.
• Tuning is performed while no
motor is connected.
• he cables connecting the inverter
to the motor are too long; they are
more than 30m in length.
• Tuning is performed while the
motor is running.
•Make sure that a motor is connected.
•Make sure that the motor is at standstill.
•Perform auto-tuning 1 again and if the error
persists, perform tuning manually.
GVP
H tuning
error
• Tuning required to leak inductance
as specified with H cannot
be performed.
•Tuning required to boost torque as
specified with f410 cannot be performed.
•The capacity of the motor
connected is 2 notches or more
smaller than the inverter capacity.
•The motor connected is not a
three-phase inductive motor.
• Tuning is performed while no
motor is connected.
• he cables connecting the inverter
to the motor are too long; they are
more than 30m in length.
• Tuning is performed while the
motor is running.
•Make sure that a motor is connected.
•Make sure that the motor is at standstill.
•Perform auto-tuning 1 again and if the error
persists, perform tuning manually.
GVP Motor constant
setting error
Some items indicated on the motor
nameplate are not entered correctly.
• Base frequency WN
• Base frequency voltage XNX
• Motor rated capacity H
• Motor rated current H
• Motor rated speed H
• Make sure that all items on the motor nameplate
are entered correctly.
*Presence or absence of parameter trip can be selected.
