Level
Alarm Name Cause/Treatment
0B7
Cold start
Magnetic pole
indeterminacy
Cause : The controller detects the magnetic pole phase
when the servo is tuned ON for the first time after
turning ON the power. This error indicates that the
magnetic pole phase cannot be detected after the
specified period.
1) Contact error or breakage at the connector of the
motor relay cable.
2) Brake cannot be released on a controller
equipped with a brake.
3) Detection of the motor is not performed properly
because an external force is applied.
4) Large slide resistance of the actuator itself
Treatment : 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
see if the brake makes a “clicking” sound. If the
brake is not making any noise, check if the
power is supplied to the brake properly.
3) Check for abnormality in the assembly condition.
4) It the transportation weight is in the acceptable
range, cut off the power to check the slide
resistance manually by moving with hand.
If the actuator itself is suspected to be the cause,
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 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.
