Control method
If start signal ST* is turned OFF during movement, the actuator can be paused.
Use the control method for interlock in case where an object is invaded into the moving
direction of the actuator being moved.
1) If the ST* signal is turned OFF during movement, the actuator is decelerated to a stop. The
deceleration is the value set in the position table.
2) If the ST* signal is turned ON again, the remaining movement is continued. The acceleration
is the value set in the position table.
