Code Error Cause/action
0CB Current-sensor offset
adjustment error
The status of the current detection sensor in the controller is checked during
the initialization process. This alarm indicates that the sensor was found
abnormal as a result of this check.
Cause: [1] Faulty current detection sensor or peripheral component
[2] Inappropriate offset adjustment
Action: The board must be replaced or offset must be adjusted. Contact IAI.
0E0 Overload Cause: [1] The 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 large in some areas.
Action: [1] Check the load and its surroundings. If the load is receiving any
abnormal external force, make the necessary corrections to
remove the force.
[2] Turn on the brake release switch to see if the brake is released.
If the brake is not released, the brake itself may be faulty, or an
open cable or faulty brake circuit component in the controller is
suspected, among others.
[3] If the load can be moved by hand, do so to check for any area
where the slide resistance increases.
If [2] or [3] is the case, contact IAI.
Note: Be sure to remove the cause of the alarm before resuming the
operation. If the power has been cut off, wait for at least 30 minutes
before reconnecting the power to prevent the motor coil from being
burned.
0E8 Open phase A/B
detected
Encoder signals cannot be detected correctly.
Cause: [1] The connector of the encoder relay cable is loose or its circuit is
open.
[2] The connector of the supplied actuator cable is loose or its
circuit is open.
Action: Check the connection condition of the encoder relay cable and
perform continuity check. If no abnormality is found, contact IAI.
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.
