Alarm Name Cause/Treatment
0F4 Mismatched PCB This controller uses a different print circuit board depending on
the motor capacity.
The PCB is not applicable for the connected motor in the startup
check.
Cause : The actuator may not match the controller. Check
the model.
Treatment : Should this error occur, please contact IAI.
0F5 Nonvolatile memory write
verify error
It is verified at the data writing process to the non-volatile
memory that the data inside the memory and the data to be
written are matched. There was a mismatch detected in this
process.
Cause : Faulty nonvolatile memory.
Treatment : When the error is caused even when the power is
re-input, please contact IAI.
0F6 Nonvolatile memory write
timeout
There is no response in the specified time duration during the
data writing to the non-volatile memory.
Cause : Faulty nonvolatile memory.
Treatment : When the error is caused even when the power is
re-input, please contact IAI.
0F8 Nonvolatile memory data
destroyed
Abnormal data was detected during the nonvolatile memory
check after starting.
Cause : Faulty nonvolatile memory.
Treatment : When the error is caused even when the power is
re-input, please contact IAI.
0FA CPU error The CPU operation is not normal.
Cause : 1) Faulty CPU
2) Malfunction due to noise
Treatment : When the error is caused even when the power is
re-input, please contact IAI.

Cold start
FPGA error
(Faulty component)
The FPGA is not operating properly.
Cause : 1) Malfunction due to the effect of noise, etc.
2) Faulty FPGA
3) Faulty circuit component around the FPGA.
4) Inappropriate board installation in the controller.
Treatment : Turn the power off and reboot.
If the error occurs again, check for presence of
noise.
If a spare controller is available, replace the
problem controller with the spare controller. A
recurring error with the spare controller suggests
presence of noise.
If the cause cannot be identified, please contact IAI.
