The electric actuator goes out the stroke limit specified by the basic
parameters, “Stroke (+)” and “Stroke (-)” if it performs the requested
operation. (Including JOG operation after return to origin)
This occurs only when the SETON output is ON.
<Countermeasure>
Make sure that the basic parameter, “Stroke (+)” and “Stroke (-)” are
consistent with the distance of electric actuator movement specified in
the step data.

1. Return to origin is not completed within the set time.
2. Return to origin parameter has the conditions shown below.
Parameter setting content
Limit switch origin [Sensor]
Alarm is generated with condition above when the sensor is not mounted
to the electric actuator.
<Countermeasure>
(1) Check that the electric actuator’s movement is not interrupted.
(2) Check that the return-to-origin parameter is set correctly.
<Contents>
While the servo motor is off (when EMG terminal is not energized), the
return to origin operation, JOG operation or MOVE operation is
requested.
<Countermeasure>
Command operation while the servo motor is on (SVRE output is on).
Apply 24 VDC to the EMG terminal.

Return to origin parameter has the conditions shown below.
Return to origin parameter setting
Pushing origin
operation [Stop]
Limit switch origin
[Sensor]
The origin sensor is not effective.
[Disabled]
or Sensor N.O type [N.O]
Alarm is generated with condition above when the sensor is not mounted
to the electric actuator.
<Countermeasure>
Sensor installation and return to origin parameter and motor and sensor
type is setting to have confirmed.
<Contents>
The alarm is generated when the communication between the driver ciruit
and the absolute ciruit is not normal. (This driver has not absolute
function.)
<Countermeasure>
Make sure that the sensor type of the basic parameter is 1. After the
parameter is changed, it is necessary to reapply the power.
