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
Action: The board must be replaced.
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 work and its surroundings. If the work 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 work 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: Before restarting operation, be sure to remove the cause.
If the power is cut off once, input the power again after 30 min or more have
elapsed to prevent the motor coil from burnout.
0E8 Phase-A/B disconnection
detection Encoder signals cannot be detected correctly.
Cause:
[1] Loose or disconnected encoder-relay cable connector
[2] Loose or disconnected actuator-end connector of the supplied cable
Action: Check the connection condition of the encoder relay cable and conduct
a continuity check. If the results are normal, please contact IAI.
0F4 Mismatched PCB This controller has a different motor drive circuit in accordance with the motor
capacity. Therefore, a mounted motor is determined based on the printed circuit
board (PCB).
To this end, it is checked in the initialization process after starting whether the
motor type set in the applicable system parameter matches the board.
The alarm indicates that the motor type does not match the board.
Cause: A parameter input error or board assembling error is suspected.
Action: Should this error occur, please contact IAI.
