(3) Cold Start Alarms
Code Error Cause/action
0C8 Overcurrent Cause: The output current from the power circuit became abnormally
high.
This alarm does not occur in normal conditions of use, but it
may occur when the motor coil isolation has deteriorated.
Action: Measure inter-phase resistance between motor connection
leads U, V and W as well as isolation resistance relative to the
ground, to check for deterioration of isolation.
Please contact IAI before performing these measurements.
0CB Current sensor offset adjustment error The condition of the current detection sensor in the controller is checked
in the initialization process after the controller is started. This alarm
occurs when a sensor error was found in this check.
Cause: [1] Faulty current detection sensor or peripheral part
[2] Inappropriate offset adjustment
Action: You must change the board or adjust the offset.
Please contact IAI.
0D8 Deviation overflow The position deviation counter has overflowed.
Cause: [1] The work part hit a nearby object during movement, and the
speed has decreased as a result.
[2] The acceleration setting is too high with respect to the
payload.
[3] The brake is not fitted correctly and thus it cannot be
released properly.
Action: [1] Revise the mechanism around the work part so that strong
external force will not apply to the work part.
If [2] or [3] is suspected, please contact IAI.
0E4 Encoder send error The controller and encoder exchange position data via serial
communication.
This error occurs when the data sent from the controller could not be
received by the encoder successfully.
Cause: [1] Garbage data due to noise
[2] Faulty communication IC mounted on the encoder board
[3] Faulty communication IC mounted on the controller board
Action: [1] Turn off the power to all peripherals and move only the
controller and actuator. If the error does not occur, noise is
the likely cause.
In the case of [2] or [3], the encoder or controller must be
replaced.
If the cause cannot be specified, please contact IAI.
