10. Troubleshooting
Code Error name Cause/Action
0F4 Unmatched PCB This controller uses a different motor drive circuit depending on the motor
capacity, and thus adopts a different printed circuit board (PCB)
appropriate for each motor capacity.
For this reason, whether the motor type set by the applicable
manufacturer’s parameter matches the board is checked in the initialization
process after startup.
This error indicates that the two do not match.
Cause: The parameter was not entered correctly or the correct board was
not assembled.
Action: Should this error occur, please contact IAI.
0F5 Nonvolatile memory
write verification error
When data has been written to the nonvolatile memory, the written data is
read again to check (verify) if it matches the original data.
This error indicates that the two data do not match.
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 generates again after reconnecting the power, please
contact IAI.
0F6 Nonvolatile memory
write timeout
This error indicates that response is not received within the specified time
after data was written to the nonvolatile memory.
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 generates again after reconnecting the power, please
contact IAI.
0F8 Damaged nonvolatile
memory
Abnormal data was detected during the nonvolatile memory check after
starting.
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 generates again after reconnecting the power, please
contact IAI.
0FA CPU error The CPU is not operating properly.
Cause: [1] Faulty CPU
[2] Malfunction due to noise
Action: If the alarm generates again after reconnecting the power, please
contact IAI.
