3. Operation
3.2.2 Power Input
1) Release the emergency stop status or enable the motor driving power supply.
2) Supply 24V DC for the I/O.
3) Supply 24V DC for the controller.
4) Input the Servo-motor ON signal from the PLC side
(*3)
.
5) Input the Backward Position movement command and signals at fi rst from the PLC side.
[Refer to 3.2.3 Home-return]
Note 1
. When the home return operation is set to “MANU” in the initial setting and the fi rst ST0 is turned ON, the
actuator is returned to the home position and the operation is started.
When it is set to “AUTO”, the actuator is returned to the home position automatically after the servo-motor
ON is input.
The above are effective only when the actuator is incremental type (for the absolute type, the home return
operation is not required).
Note
2. The Servo-motor ON signal is input for the fi rst time after the power input, input the movement command
after the delay time of 1.6sec or more.
In the second time or later, make the delay time of 60ms or more.
Note
3. When the Servo-motor Control is set to “Enable” in the initial setting, the servo-motor is turned ON by
means of inputting the SON signal.
When it is set to “Disable” the servo-motor is turned ON automatically.
Warning: For ASEP and PSEP
The magnetic pole phase detection may not be performed normally if the servo is turned on near
the mechanical end, and may cause such problems like an abnormal operation, magnetic pole not
being defi ned or electromagnetic detection error.
Put it away from the mechanical end when turning the servo on.
