Code Error name Cause/Action
0C2 Overrun sensor signal
detected
This error indicates that a signal from the OT sensor installed at a mechanical
end was detected.
Cause: [1] The actuator was moved by hand or received an external force
while the servo was off (normal detection).
[2] The actuator was jogged in a condition where the home
coordinates were not yet established and thus the soft stroke
check did not function correctly (normal detection).
[3] The home position achieved by home return is not correct, or in the
case of an absolute type controller the coordinates have shifted
due to an inappropriate absolute reset position.
[4] The sensor characteristics do not match the setting of sensor
parameter No. 19, or the sensor is wired wrongly.
[5] The controller and actuator combination is wrong, or the soft limit
or screw lead set in the controller is not appropriate.
Action: If [1] or [2] is suspected, move the actuator in the opposite direction by
hand.
If this error occurred inside the effective stroke range, [3], [4] or [5] is a
likely cause. Check the home position, parameter setting, wiring, etc.
If the cause cannot be specified, contact IAI.
0CF 24-V I/O power error Cause: The 24-V PIO power supply is abnormal.
Action: Turn on the 24-V PIO power first, and then turn on the controller
power.
0D2 Motor power-supply
voltage excessive
Supported version: Up to V001A
Please refer to the cold start level code “0D2” for the detailed information.
0D3 Motor power-supply
voltage low
Supported version: Up to V001A
Please refer to the cold start level code “0D3” for the detailed information.
0D8 Deviation overflow The position deviation counter has overflowed.
Cause: [1] The speed dropped while the actuator was moving due to the
effect of an external force, etc.
[2] The excited-phase detection operation following the power on is
unstable.
[3] The power-supply voltage dropped.
Action: [1] Check the loading condition, such as whether the load is
contacting with any surrounding object or if the brake is released,
and remove the cause of the problem found.
[2] Since an overload condition is suspected, review the load weight.
Reconnect the power, and then perform home return.
[3] Check the power-supply voltage.
0D9 Software stroke limit
exceeded
Cause: After completion of home return, the current actuator position is
outside the software stroke limits.
Action: Move the actuator to a position inside the software stroke limits.
0DA Feedback pulse error Cause: The feedback pulse data could no be output within the specified cycle.
Action: Implement noise elimination measures.
0DC Out of push & hold
operation range error
This error occurs when the actuator was pushed back to the target position due
to an excessive push force after completion of push & hold operation.
Review the entire system.
0F5 Nonvolatile memory
write verification error
Supported version: Up to V001A
Please refer to the cold start level code “0F5” for the detailed information.
