Error
Code
Name
Cause(s)
Main circuit
error
The inverter will trip if the power supply establishment is
not recognized because of a malfunction due to noise or
damage to the main circuit element.
Driver error
An internal inverter error has occurred at the safety
protection circuit between the CPU and main driver unit.
Excessive electrical noise may be the cause. The inverter
has turned OFF the IGBT module output.
Thermistor
When a thermistor is connected to terminals [5] and [L]
and the inverter has sensed the temperature is too high,
the inverter trips and turns OFF the output.
Braking error
When "01" has been specified for the Brake Control
Enable (b120), the inverter will trip if it cannot receive the
braking confirmation signal within the
Brake Wait Time for Confirmation (b124) after the output
of the brake release signal.
Safe Stop
Safe stop signal is given when b145 =01.
Low-speed overload protection
If overload occurs during the motor operation at a very low
speed, the inverter will detect the
overload and shut off the inverter output.
Operator connection
When the connection between inverter and operator
keypad failed, inverter trips and displays the error code.
Modbus communication error
When
“trip” is selected (C076=00) as a behavior in case of
communication error, inverter trips when timeout happens.
EzSQ invalid instruction
The program stored in inverter memory has been
destroyed, or the PRG terminal was turned on without a
program downloaded to the inverter.
EzSQ nesting count error
Subroutines, if-statement, or for-next loop are nested in
more than eight layers
EzSQ instruction error
Inverter found the command which cannot be executed.
to
EzSQ user trip (0 to 9)
When user
–defined trip happens, inverter trips and
displays the error code.
to
Option error
The inverter detects errors in the option board mounted in
the optional slot. For details, refer to the instruction
manual for the mounted option board.
NOTE
:
Reset is not allowed in 10 second after trip.
NOTE
:
When error E08, E14 and E30 occur, reset operation by RS terminal or STOP/RESET key is
not accepted. In this case, reset by cycling power. If still same error occurs, perform initialization.
NOTE
:
When error E37 occur, reset operation by STOP/RESET key is not accepted. In this case,
reset by cycling power. If still same error occurs, perform initialization.
