Code Error Cause/action
0C0 Excessive actual speed Cause: The motor speed exceeds the maximum speed set by the manufacturer’ s
parameter.
This alarm does not generate during normal operation, but it may occur if the
load decreased before a servo error was detected and the motor speed has
increased as a result. This condition occurs due to the following reasons:
[1] The slide resistance of the actuator is large in some areas.
[2] The load increased due to momentary application of external force.
Action: Check the assembly condition of mechanical parts for any abnormality. If the
actuator itself is suspected as the cause, contact IAI.
0C1 Servo error This alarm indicates that after the acceptance of the move command, the motor could
not operate for 2 seconds or more before the actuator reached the target position.
Cause:
[1] The connector of the motor relay cable is loose or its circuit is 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.
he actuator itself is high.
Action: [1] Check the wiring condition of the motor relay cable.
[2] Check the wiring condition of the brake cable, and also turn on/off the
brake release switch to check if “click” sound is heard.
[3] Check the assembly condition of mechanical parts for any abnormality.
check the slide resistance.
ted as the cause, contact IAI.
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 C 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.
[4] The sliding resistance of t
[5] The positioning band setting is smaller than the encoder resolution.
[5] Set the positioning band value greater than that of the encoder
[4] If the load is normal, cut off the power and move the actuator by hand to
If the actuator itself is suspec
resolution.
