If it is found that replacement of parts is required or the problem cannot be solved by any remedy described in the
table, contact your Toshiba distributor.
[Trip information]
Error code
Failure
code
Problem Possible causes Remedies
E 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.
If the emergency stop signal is input, reset
after releasing this signal.
E-13 0045 Over speed fault
The input voltage fluctuates abnormally.
Over speed fault due to the overvoltage
limit operation.
Check the input voltage.
Install an optional braking module.
*
E-18 0032 Brea in analog signal
cable
The input signal from VI is equal to or
less than the setting.
Check the VI signal cable for breaks. Also, check
the input signal value or setting of .
E-19 0033 CPU communications
error
A communications error occurs between
control CPUs.
Contact your Toshiba distributor.
E-20 0034 Excessive torque
boosted
The automatic torque boost parameter
setting is too high.
The motor has too small impedance.
Set a lower automatic torque boost
parameter setting.
Make an auto-tuning.
E-21 0035 CPU fault 2
The control CPU is defective. Contact your Toshiba distributor.
E-26 003A CPU fault 3
The control CPU is defective. Contact your Toshiba distributor.
EEP1 0012 EEPROM fault 1
The EEPROM is writing error. Turn off the inverter, then turn it again. If it
does not recover from the error, contact
your Toshiba distributor.
EEP2 0013 EEPROM fault 2
typ operation was aborted by power
supply off etc.
The EEPROM is reading error.
Turn the power off temporarily and turn it
back on, and then try operation
again.
Write the data again. Contact your Toshiba
distributor when it happening frequently.
EEP3 0014 EEPROM fault 3
The EEPROM is defective. Turn off the inverter, then turn it again. If it
does not recover from the error, contact
your Toshiba distributor.
EF2 0022 Ground fault trip
A ground fault occurs in the output cable
or the motor.
Check the cable and the motor for ground
faults.
*
EPHI 0008 Input phase failure
A phase failure occured in the input line
of the main circuit.
The capacitor in the main circuit lacks
capacitance.
Check the main circuit input line for phase
failure.
Set input phase failure detection selection
f608=0.
Check the capacitor in the main circuit for
exhaustion.
*
EPHO 0009 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.
Set output phase failure detection
selection f605=0.
ERR2 0015 Main unit RAM fault
The control RAM is defective. Contact your Toshiba distributor.
ERR3 0016 Main unit ROM fault
The control ROM is defective. Contact your Toshiba distributor.
ERR4 0017 CPU fault 1
The control CPU is defective. Contact your Toshiba distributor.
ERR5 0018 Remote control error
The communication was broken off. Check the remote control device, cables, etc.
* You can select a trip ON/OFF by parameters.
