0C9 Excessive motor
power-supply voltage This alarm indicates that the voltage of the motor power supply is excessive (24 V
+ 20%: 28.8 V or above).
Cause:
[1] The voltage of the 24-V input power supply is high.
[2] Faulty part in the controller
Action: Check the input power-supply voltage.
If the voltage is normal, contact IAI.
0CA Overheat This alarm indicates that the temperature around the power transistor in the
controller is excessive (95
oC or above).
Cause: [1] High surrounding temperature
[2] Defective part in the controller
Action: [1] Lower the temperature around the controller.
If the condition in [1] is not applicable, contact IAI.
0CC Excessive control
power-supply voltage This alarm indicates that the voltage of the 24-V input power supply is excessive
(24 V + 20%: 28.8 V or above).
Cause:
[1] The voltage of the 24-V input power supply is high.
[2] Faulty part in the controller
Action: Check the input power-supply voltage.
If the voltage is normal, contact IAI.
0CE Low control power-supply
voltage This alarm indicates that the voltage of the 24-V input power supply is low (24 V –
20%: 19.2 V or below).
Cause:
[1] The voltage of the 24-V input power supply is low.
[2] Faulty part in the controller
Action: Check the input power-supply voltage.
If the voltage is normal, contact IAI.
0D8 Deviation overflow The position deviation counter has overflowed.
Cause:
[1] The speed dropped while the actuator was moving due to external
force, etc.
[2] Unstable excitation detection operation after the power was turned
on
Action: [1] Check the load condition, such as whether the work is contacting
any peripheral equipment or the brake is released, and remove the
cause of the identified problem.
[2] Overload condition is suspected, so check the load.
Reconnect the power, and then perform homing.
0D9 Software limit exceeded
error Cause: [1] When installation was vertical and the target location was close to
the software limit, software limit was exceeded due to overshoot if
load was large or deceleration setting was large
[2] The servo ON operation was attempted after moving outside the
software limit range in the servo-OFF state.
Action: [1] Set the deceleration curve that prevents overshooting upon
stopping.
[2] Perform the servo-ON operation after returning to the software limit
range.
