Alarm
Code
Alarm
Level
Alarm Name Cause/Treatment
0A8 Unsupported
motor/encoder types
Cause : The motor connected to the controller is not
applicable or the type of the encoder that the motor
is connected is not applicable.
Treatment : Please contact us if the alarm is issued even with
the applicable actuator and the same problem
happens again even after rebooting the power.
0B4
Cold start
Electric angling
mismatching
Cause : This alarm indicates that the position deviation
counter has overflowed.
Treatment : The alarm occurs when the actuator cannot be
operated.
Confirm about the load conditions, that the work
does not interfere with any object nearby or the
brake has been released, etc.
If the error occurs even when the servo is ON,
breakage of the encoder cable is considered.
Check the cable connection. Please contact IAI if
there is no failure in the cable and connector
connections.
0B5 Z-Phase position error The position where the Z-phase is detected before the home
return operation, is out of the specified range.
Cause : Encoder Error
Treatment : Please contact IAI.
0BA Home sensor
non-detection
Cause : This indicates that the home-return operation of the
actuator equipped with origin sensor (option except
rotary actuator) is not completed in normal
condition.
1) Work is interfering with peripheral equipment in
the middle of home return.
2) Large slide resistance of the actuator itself
3) Installation failure, breakdown or disconnection
of the home sensor
Treatment : In the case that the work does not interfere with
anything, the cause 2) or 3) is supposed. In such
case, please contact IAI.
0BE Home return timeout Cause : Home return does not complete after elapse of a
certain period after the start of home return.
Treatment : This error does not occur in normal operation. The
combination of the controller and actuator may be
incorrect. Please contact IAI.
0BF
Operation
release Creep sensor not
detected
Cause : This indicates the actuator detected the creep
sensor (option) before detecting the origin sensor
(option except for rotary actuator), or the actuator
reached the mechanical end (or the actuator cannot
move anymore because the load is too large).
1) The position to apply the creep sensor, which is
moved after the product was delivered, is not
appropriate.
2) The creep sensor is faulty.
3) The cable is disconnected or the connector is not
plugged in properly.
4) The actuator cannot move due to heavy load
caused by interference.
Treatment : 1) Readjust the sensor installation position.
2) Replace the creep sensor.
3) Perform continuity check to see if the connector
is plugged in properly.
4) Check the interference and the transportable
weight and make sure there is no external force
applied.
