Error
Code
Name Cause(s)
E25
Main circuit
error (*3)
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.
E30
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.
E35
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.
E36
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.
E37
Safe Stop Safe stop signal is given.
E38
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.
E40
Operator connection When the connection between inverter and operator
keypad failed, inverter trips and displays the error code.
E41
Modbus communication error When “trip” is selected (C076=00) as a behavior in case of
communication error, inverter trips when timeout happens.
E43
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.
E44
EzSQ nesting count error Subroutines, if-statement, or for-next loop are nested in
more than eight layers
E45
EzSQ instruction error Inverter found the command which cannot be executed.
E50
to
E59
EzSQ user trip (0 to 9) When user –defined trip happens, inverter trips and
displays the error code.
E60
Option error (DeviceNet
Communications error)
If the disconnection due to the Bus-Off signal or timeout
occurs during the operation using DeviceNet commands,
the inverter will shut off its output and display the error
code shown on the right.
(The inverter will trip according to the settings of "P045"
and "P048".)
E61
Option error (duplicated MACID) If two or more devices having the same
MAC ID are detected in the same network, the inverter will
display the error code shown on the right.
E62
Option error (External trip) If the Force Fault/Trip bit of Attribute 17 in the Instance 1
of the Control Supervisory object is set to "1", the inverter
will shut off its output and display the error code shown on
the right.
E63
to
E68
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.
E69
Option error (inverter communication
error)
If timeout occurs during the communication between the
inverter and DeviceNet option board, the inverter will shut
off its output and display the error code shown on the
right.
E80
Encoder
disconnection
If the encoder wiring is disconnected, an encoder
connection error is detected, the encoder fails, or an
encoder that does not support line driver output is used,
the inverter will shut off its output and display the error
code shown on the right.
