Magnetic Pole
Indeterminate
For this controller, when the servo-motor is turned ON for the fi rst time after the power is input,
the magnetic pole phase detection (pole sensing) is performed. At that time, the magnetic pole
phase is not detected after the specifi ed time period.
Cause : (1) A looseness in the connection section of the actuator connecting cable or wire
breakage is considered.
(2) In the case of the unit with the brake, the brake is not released.
(3) The motor load might be too large due to the external force.
(4) The sliding resistance in the actuator itself might be too large.
Treatment : (1) and (2) Check for the actuator connecting cable wiring condition.
(3) Confi rm that there is no error in the mechanical part assembly condition.
(4) In the case that the load weight is normal, move the actuator by hand to check
the sliding resistance after the power is turned OFF. In the case that there is any
error in the actuator itself, contact our company.
0B8
Excitement Detection
Error
For this controller, when the servo-motor is turned ON for the fi rst time after the power is input,
the magnetic pole phase detection (pole sensing) is performed. However, the specifi ed encoder
signal level is not detected after the excitement for the specifi ed time period.
Cause : (1) A looseness in the connection section of the actuator connecting cable or wire
breakage is considered.
(2) In the case of the unit with the brake, the brake is not released.
(3) The motor load might be too large due to the external force.
(4) The power is input while the actuator hits the mechanical end.
(5) The sliding resistance in the actuator itself might be too large.
Treatment : (1) and (2) Check for the motor connecting cable wiring condition.
(3) Confi rm that there is no error in the mechanical part assembly condition.
(4) Move the actuator away from the mechanical end and re-input the power.
(5) In the case that the load weight is normal, move the actuator by hand to check
the sliding resistance after the power is turned OFF. In the case that there is any
error in the actuator itself, contact our company.
Operation
Cancellation
0BA
Home Position Sensor
Indetectable
For the actuator for which the home return sensor is used, the home return operation has not
been completed normally.
Cause : (1) The work interferes with the surrounding object in the course of the actuator’s
home return operation.
(2) The actuator’s sliding resistance might be partly too high.
(3) The home return check sensor installation error, breakdown or wire breakage is
supposed.
Treatment : In the case that the work does not interfere with anything, the cause (2) or (3) is
supposed. In such case, contact our company.
0BE Home Return Time Out
Cause : Even when the specifi ed time period has passed after the home return operation
start, the home return operation is not completed (It never occurs in the normal
operation).
Treatment : It is considered that the combination of the controller and actuator is not correct.
Contact our company.
0C0 Actual Speed Excessive
Cause : The motor speed exceeds the maximum motor speed set using the maker’s set
parameters.
(1) The actuator’s sliding resistance might be partly too high.
(2) The load is increased too much due to the momentary external force.
It might be caused when the load is lightened before detecting the servo-motor
error due to the above causes (1) and (2), and the actuator is moved suddenly.
Treatment : Check that there is no error in the mechanical part assembly condition.
In the case that there is any error in the actuator itself, contact our company.
