Part 3 Maintenance
Code Alarm name Cause/action
0CC Control
power-supply
overvoltage
This alarm indicates that the 24-V input power-supply voltage is excessively high (24 V +
20%: 28.8 V or above).
Cause: [1] The 24-V input power-supply voltage is high.
[2] A faulty part inside the controller
Action: Check the input power-supply voltage.
If the voltage is normal, please contact IAI.
0CE Control
power-supply
voltage low
This alarm indicates that the 24-V input power-supply voltage is low (24 V - 20%: 19.2 V
or below).
Cause: [1] The 24-V input power-supply voltage is low.
[2] A faulty part inside the controller
Action: Check the input power-supply voltage.
If the voltage is normal, please contact IAI.
0D2 Motor
power-supply
overvoltage
(RACON only)
Cause: [1] The input power-supply voltage of the motor is high.
[2] A faulty part inside the controller
Action: Check the input power-supply voltage of the motor.
If the voltage is normal, please contact IAI.
0D8 Deviation
overflow
The position deviation counter has overflowed.
Cause: [1] The speed dropped during movement due to the effect of an external force,
etc.
[2] The acceleration is set too high for the loading mass.
Action: [1] Check the load conditions—such as whether the work part is contacting a
surrounding object or the brake is released—and then correct the
abnormality, if any.
[2] An overload condition is suspected, so review the payload.
0D9 Soft limit over
error
Cause: The current position of the actuator is outside the software stroke limits
following the completion of home return.
Action: Move the actuator to a position within the software stroke limits.
0DC Push & hold
operation
out-of-range error
This alarm generates 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.
0ED Absolute encoder
error (1)
Cause: [1] When the power was reconnected following the completion of an
absolute reset, the current position changed due to an external factor or other cause
occurring while the controller was communicating with the absolute unit.
[2] When an absolute reset was performed, the current position changed due to an
external factor or other cause occurring while the controller was communicating with the
absolute unit.
Action: [1] When the detail code is H’0001:
Turn off the power and make sure the actuator is not receiving vibration, etc., and then
turn the power back on.
[2] When the detail code is H’0002:
Perform the home return operation after making sure the actuator is not receiving
vibration, etc.
