Error
code
Description Possible causes Remedies
G Emergency stop
•Inverter is stopped by panel
operation during automatic or
remote operation.
•A stop command (input terminal
function:  or ) is issued by
an external control device.
•Reset the inverter.
GGR
EEPROM error
•A data writing error occurs.
•Turn off the inverter, then turn it again. If it does
not recover from the error, Contact your Toshiba
distributor.
GGR
Initial read error
•Some internal data is corrupted.
•Power was turned off while V[R
was being set.
•Contact your Toshiba distributor.
•Set V[R again. If the inverter does not recover
from the error, Contact your Toshiba distributor.
GGR
I
nitial read error
•Some internal data is corrupted.
•Contact your Toshiba distributor.
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 p
hase failure occurred in the
output line of the main circuit.
•
The
motor
is not
connected.
•Check the main circuit output line, motor, etc. for
phase failure.
•
Select output phase failure detection parameter
H
.
•
Make sure that a motor is connected.
*
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.
•Contact your Toshiba distributor.
GTT
Main unit RO
M
fault
•The control ROM is defective.
•Contact your Toshiba distributor.
GTT
CPU fault
•The control CPU is defective.
•Contact your Toshiba distributor.
GTT
Interruption of
operation
command from
external control
device
•
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.
•Contact your Toshiba distributor.
GTT
Output current
detector error
•The main output current detector
is defective.
•Contact your Toshiba distributor.
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 Sec
tion 6.42
.
GTT
Extended panel
option. cable is
broken
•
10 seconds
disconnection
is
detected by the setting H=0
(disconnection detection)
•
Confirm the connection
between extended panel
option (RKP002Z,RKP004Z) and inverter.
GVP
Tuning error
•
It was
unable to auto tuning
normally.
•The internal system error occurred
during auto tuning
.
•
Perform auto
-
tuning
1
again and if the error
persists, contact your Toshiba distributor.
GVP
Tuning
detection error
•
Some of
H
,
H
,
H and H were not to
be detected during auto tuning.
•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.
•The 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
value error
•
Some detection values
of
H,H,H and
H were beyond the limits of
normal value.
•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.
•The 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 the motor is at standstill.
•Perform auto-tuning 1 again and if the error
persists, perform tuning manually.
*Presence or absence of parameter trip can be selected.
