n o i t c A / e s u a C e m a n r o r r E e d o C
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 extension 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.
Action: [1] Check the wiring condition of the motor extension 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.
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 (95 C or above).
Cause: [1] The surrounding 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 work part 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.
[5] The positioning band setting is smaller than the encoder resolution.
[4] The slide resistance of the actuator itself is high.
[5] Set the positioning band value greater than that of the encoder
If the actuator itself is suspected as the cause, please contact IAI.
resolution.
