Code Error name Cause/Action
0B5 Phase-Z position error The position at which phase Z was detected during home return was
outside the specified range, or phase Z was not detected.
Cause: Faulty encoder
Action: Contact IAI.
0BA Home sensor non-detection This alarm indicates that the actuator with a home sensor used did not
normally complete home return operation.
Cause: [1] Work is interfering with peripheral equipment in the middle of
home return.
[2] The slide resistance of the actuator is locally high.
[3] Installation failure, breakdown or disconnection of the home
check sensor
Action: If the work is not interfering with peripheral equipment, the cause
of [2] or [3] is suspected. Please contact IAI.
0BE Home return timeout Cause: Home return is not completed within the period set in the
applicable system parameter after the start of home return
operation.
(This alarm will not be generated in normal operation.)
Action: The combination of the controller and actuator may be incorrect.
Please contact IAI.
0C0 Excessive actual speed Cause: This alarm indicates that the motor speed exceeded the maximum
speed set in the applicable system parameter.
This alarm will not be generated in normal operation, but may
occur in the following condition:
[1] The slide resistance of the actuator is locally high.
[2] Instantaneous increase in load due to application of external force,
which may cause the load to decrease and actuator to move
rapidly before a servo error is detected.
Action: Check the assembly condition of mechanical parts for abnormality.
If the actuator itself is suspected to be the cause, please contact
IAI.
0C9 Excessive motor supply
voltage
This alarm indicates that the motor supply voltage is excessive
(24V+20%, 28.8V or more).
Cause: [1] High voltage of 24V input power supply
[2] Faulty part inside the controller
Action: Check the voltage of the input power supply.
If the voltage is normal, please contact IAI.
0CC Abnormal control supply
voltage
This alarm indicates that the voltage of the 24V input power supply is
excessive (24V+20%: 28.8V or more).
Cause: [1] High voltage of 24V input power supply
[2] Faulty part inside the controller
Action: Check the voltage of the input power supply.
If the voltage is normal, please contact IAI.
0CE Drop in control supply
voltage
This alarm indicates that the voltage of the 24V input power supply has
dropped (24V-20%: 19.2V or less).
Cause: [1] Low voltage of the 24V input power supply
[2] Faulty part inside the controller
Action: Check the voltage of the input power supply.
If the voltage is normal, please contact IAI.
