[6] Pause and Operation Interruption (ST*, *STP, RES, PE*, PEND)
In this mode, there are two ways as shown below to pause the operation during a move.
1) Use of pause signal *STP
Turning reset signal RES ON during the pause allows the remaining moving distance to be
cancelled to interrupt the operation.
2) Use of start signal ST*
This method is valid when Parameter No.27 “Move command type” is set to “0” (factory
setting). The actuator can only be moved while the ST* signal is set to ON and stopped if
ST* is turned OFF. Since setting the ST* signal to OFF is assumed as interrupt of operation,
the remaining moving distance may not be cancelled.
(1) Use of pause signal *STP
■ Control method
The pause signal is an input signal always set to ON. So, it is normally used to remain ON.
Use this function for interlock in case where an object is invaded into the moving direction of the
actuator being moved.
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) During pause, current position No. PE* and positioning complete signal PEND are not turned
ON.
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.
4) Turning reset signal RES ON during pause (*STP during OFF) allows the remaining
movement to be cancelled to interrupt the operation.

Caution： Caution on First-Order Lag Filter
● At occurrence of an alarm in the release level
(Note 1)
, RES can reset the alarm. Cancel
the remaining moving distance after confirmation that alarm signal *ALM (being ON in
normal state and OFF at occurrence of an alarm) is set to ON.
Note 1 Refer to [8.3.3 Alarm Details] for details of alarms.
● 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.
