Code Error name Cause/Action
0C1 Servo error This error indicates that the motor could not be operated for 2 seconds or
more after the move command was accepted and before the target position
was reached.
Cause: [1] The motor relay cable connector is loose or open.
[2] If the actuator is equipped with a brake, the brake cannot be
released.
[3] The load increased due to application of external force.
[4] The slide resistance of the actuator itself is high.
Action: [1] Check the wiring condition of the motor relay cable.
[2] Check the wiring condition of the brake cable. Also, turn on/off
the brake release switch and check if the brake makes “click”
sounds.
[3] Check the assembly condition of mechanical parts for any
abnormality.
[4] If the payload is normal, turn off the power and move the
actuator by hand to check the slide resistance.
If the actuator itself is suspected as the cause, please contact
IAI.
0C9 Motor power-supply
overvoltage
This error indicates that the motor 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.
0CA Overheating This error indicates that the temperature around the power transistor in the
controller is excessively high (95C or above).
Cause: [1] The surrounging air temperature is high.
[2] A faulty part inside the controller.
Action: [1] Lower the surrounding air temperature.
If [1] does not apply, please contact IAI.
0CC Control power-supply
overvoltage
This error 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 error 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.
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 pole sense detection operation after power on is unstable.
Action: [1] Check the load conditions—such as whether the load is
contacting a surrounding object or the brake is disengaged—
and then correct the abnormality, if any
[2] An overload condition is suspected, so review the load weight.
