Code Error name Cause/Action
0CB Current sensor offset
adjustment error
The condition of the current detection sensor inside the controller is
checked in the initialization processing after the power is input. A sensor
error was detected at this time.
Cause: [1] Faulty current detection sensor and peripheral components
[2] Inappropriately adjusted offset
Action: The board must be replaced or the offset must be adjusted.
Please contact IAI.
0E0 Overload Cause: [1] Load increased due to application of external force.
[2] If the actuator is equipped with a brake, the brake cannot be
released.
[3] The slide resistance of the actuator is locally high.
Action: [1] Recheck the surroundings of the work. If abnormal external
force was applied to the work, correct it.
[2] Turn on the brake release switch and confirm that the brake is
released. If the brake is not released, a failure of the brake itself,
cable disconnection or a faulty part of the brake circuit inside the
controller is suspected.
[3] If the work can be moved by hand, move it and check that there
is no part which is of high slide resistance.
If [2] or [3] is applicable, please contact IAI.
Note: Before restarting operation, be sure to remove the cause.
If the power is cut off once, input the power again after 30 min or
more have elapsed to prevent the motor coil from burnout.
0E8 Phase-A/B disconnection
detection
Encoder signals cannot be detected correctly.
Cause: [1] Loose or disconnected encoder-relay cable connector
[2] Loose or disconnected actuator-end connector of the supplied
cable
Action: Check the connection condition of the encoder relay cable and
conduct a continuity check. If the results are normal, please contact
IAI.
0F4 Mismatched PCB This controller has a different motor drive circuit in accordance with the
motor capacity. Therefore, a mounted motor is determined based on the
printed circuit board (PCB).
To this end, it is checked in the initialization process after starting whether
the motor type set in the applicable system parameter matches the board.
The alarm indicates that the motor type does not match the board.
Cause: A parameter input error or board assembling error is suspected.
Action: Should this error occur, please contact IAI.
0F5 Nonvolatile memory write
verify error
When data is written in the nonvolatile memory, the written data is read
once for a check to verify the data matching.
This alarm indicates that the written data is not matching.
Cause: [1] Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times.
(The nominal rewrite limit of the nonvolatile memory is around
100,000 times.)
Action: If the alarm is generated again after reconnecting the power, please
contact IAI.
