Code Alarm Name Cause/Treatment
0CA Overheat
Cause : (1) The temperature inside the controller is too high. (95
°
C or more)
(2) When the actuator is vertically installed, in the case that the deceleration setting is too high when
it is moved downward, the regenerative resistance energy might be insuffi cient.
(3) The defective part inside the controller is considered.
Treatment : (1) Lower the ambient temperature around the controller.
(2) Review the setting conditions so that the deceleration curve becomes linear.
In the case that the cause is not applicable to (1) or (2), contact our company.
0CB
Current Sensor Offset
Adjustment Error
An error is found in the current detection sensor in the initialization in the start-up operation.
Cause : (1) A breakdown of the current detection sensor or peripheral component is supposed.
(2) An error in the offset adjustment is supposed.
Treatment : A work (PC board) change or offset adjustment is required. Contact our company.
0CC
Control Power Source
Voltage Error
An over-voltage is caused in the 24V input power (24V+20%: 28.8V or more).
Cause : (1) The source voltage in the 24V power unit is too high.
(2) A breakdown of the part inside the controller is considered.
Treatment : Check for the input source voltage.
In the case that the voltage is normal, contact our company.
0CE
Control Power Source
Voltage Drop
The source voltage from the 24V power unit is decreased (24V-20%: 19.2V or less).
Cause : (1) The source voltage from the 24V power unit is too low.
(2) A breakdown of the part inside the controller is considered.
Treatment : Check for the input source voltage.
In the case that the voltage is normal, contact our company.
0D2
Motor Power Source
Voltage Excessive
An over-voltage is caused in the motor power source (24V+20%: 38V or more).
Cause : (1) The source voltage in the 24V power unit is too high.
(2) A breakdown of the part inside the controller is considered.
Treatment : Check for the input source voltage.
In the case that the voltage is normal, contact our company.
0D8 Defl ection Overfl ow
The position deviation counter is over fl own.
Cause : The velocity might be lowered in the movement operation due to an external force.
Treatment : Confi rm about the load conditions, that the work does not interfere with any object nearby or the
brake has been released, etc., and if any, remove the cause.
0D9
Software Stroke Limit-
Over Error
Cause : (1) In the case that the actuator is vertically installed and the target position is close to the soft limit,
because the load is too high, or the deceleration setting is too high, an over-chute might occur
and the actuator might exceed the soft limit.
(2) The actuator is moved out of the soft limit range when the servo-motor is turned OFF, and then
the servo-motor turning ON operation is performed.
Treatment : (1) Set the deceleration curve so that an over-chute is not caused when the actuator is stopped.
(2) Return the actuator within the soft limit range and perform the servo-motor turning ON operation.
0DC
Pressing Motion Range
Over Error
It might be caused when the actuator is pushed back to the target position because the pushing back force is
too strong after the pressing operation is completed. Review the whole system.
0E0 Overload
Cause : (1) The load is increased too much due to a external force.
(2) In the case of the unit with the brake, the brake is not released.
(3) The actuator’s sliding resistance might be partly too large.
Treatment : (1) In the case that an abnormal external force is impressed, remove it.
(2) Check that the brake is released when the servo-motor is turned ON. If not, a breakdown of the
brake, cable breakage, or defective part inside the controller, etc., is considered.
(3) In the case that the work can be moved by hand, move it. Then, check that there is no location
where a sliding resistant is too large.
If the error is caused by the above item (1) or (2), contact our company.
Note : Restart the operation after making sure to remove the cause. Also, in the case that the power is
turned OFF, turn ON the power again after 30 minutes or to prevent motor coil burning.
0E5
Encoder Signal Receipt
Error
Cause : The missing connector inside the controller is considered.
reatment : In the case that the same error is caused after the power to the controller is re-input, contact our
company.
0E7
A, B or Z-phase Wire
Breakage
The encoder signal is not detected normally.
Cause : A looseness or wire breakage in the connector section of the actuator connecting cable is
considered.
Treatment : Check for the connection condition of the actuator connecting cable and perform the continuity test.
If normal, contact our company.
