(2) Starting the servo motor
Click "Operation Start" (b) to rotate the servo motor.
(3) Pausing the servo motor
Click "Pause" (c) to temporarily stop the servo motor.
Click "Operation Start" (b) during a temporary stop to restart the rotation of the remaining travel distance.
In addition, click "Stop" (d) during a temporary stop to clear the remaining travel distance.
(4) Stopping the servo motor
