„ Control method
Pause is possible during movement. The pause signal is an input signal always set to ON. So,
it is normally used to remain ON. Use this as an interlock in such a case interference gets into
the moving direction while the actuator is operating.
1) If pause signal *STP is turned off during operation of the actuator, the actuator is
decelerated to a stop. The deceleration is defined by the value set in the position table.
2) The positioning complete signal PEND would not turn ON while in pause.
3) If pause signal *STP is returned to ON, the actuator continues the remaining movement.
The acceleration is the value set in the position table.
 
Caution: Turning *STP OFF with the actuator being in the positioning complete state
causes PEND to be turned OFF. Note that this situation may not occur
when a sequence program is created.
