Code Error Cause/action
0F4 Inconsistent PCB This controller uses a different motor drive circuit depending on the motor capacity,
and therefore the installed printed circuit board (PCB) is also different with each
controller.
During the initialization after starting, the controller checks if the motor type set by the
manufacturer’s parameter matches the actual PCB installed.
This alarm indicates that the two do not match.
Cause:
The parameter may not be entered correctly or the PCB may not be
assembled correctly.
Action: If you have encountered this error, contact IAI.
0F5 Nonvolatile memory
verification error after write When data has been written to the nonvolatile memory, the written data is read and
compared (verified) against the written data for confirmation.
This alarm indicates that the read data does not match the written data.
Cause: [1]
Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times. (The nominal
life of the nonvolatile memory is 100,000 rewrite operations.)
Action: If the problem still persists after the power has been reconnected, contact
IAI.
0F6 Nonvolatile memory
timeout after write This alarm indicates that no response was received within the specified time after
writing data to the nonvolatile memory.
Cause: [1]
Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times. (The nominal
life of the nonvolatile memory is 100,000 rewrite operations.)
Action: If the problem still persists after the power has been reconnected, contact
IAI.
0F8 Damaged nonvolatile
memory Abnormal data was detected in the nonvolatile memory check after starting.
Cause: [1]
Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times. (The nominal
life of the nonvolatile memory is 100,000 rewrite operations.)
Action: If the problem still persists after the power has been reconnected, contact
IAI.
0FA CPU error The CPU is not operating correctly.
Cause: [1]
Faulty CPU
[2] Malfunction due to noise
Action: If the problem still persists after the power has been reconnected, contact
IAI.
