Alarm Name Cause/Treatment
0BF 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.
