Alarm Name Cause/Treatment
0C5
Operation
release
Illegal transition
command in control
system
Cause : 1) Change the operation from the vibration
suppress control operation to the normal position
control operation.
2) Change the operation from the normal position
control operation to the vibration suppress
control operation.
Treatment : Change the sequence so the next action is
conducted after confirming the positioning complete
signal (PEND) is turned ON for both cases 1) and
2).
0C8 Overcurrent Cause : The output current in the power circuit section is
increased abnormally.
Treatment : This alarm will not be generated in normal
operation.
1) Degradation of motor coil insulation
2) Malfunction of components inside controller
can be concerned.
Check if there is deterioration in the insulation by
measuring the phase resistance between the
monitor connection lines U, V and W. The values for
the phase resistance should be almost the same.
There is a concern the insulation is deteriorated if
the values are different in large amount. Please
contact IAI.
0CA Overheated Cause : This indicates overheat (75qC or more) of the
components inside the controller.
1) Operation is performed with the load condition
exceeding the specified range.
2) High temperature around the controller.
3) A faulty part inside the controller.
Treatment : 1) Revise the operation condition such as
decreasing the acceleration/deceleration speed.
2) Lower the ambient temperature of the controller.
(Note) This error would not normally occur. If it occurs, confirm
there is not 1) or 2) above. If the same error is issued
again even after confirming 1) or 2) is not in the condition,
it is considered to be a malfunction. Please contact IAI.
0CB
Cold start
Current sensor offset
adjustment error
Cause : An error was found to the sensor in the status check
of the current detection sensor conducted at the
initializing process in the startup.
1) The current detection sensor or any of its
surrounding parts is faulty.
2) The actuator has moved with external force
when the power was turned ON.
Treatment : It is necessary to replace the PCB if it occurs even
after rebooting the power. Please contact IAI.
