7. Operation <Practical Steps>
z Handling of the pause (*STP) signal
This signal is a contact B signal, meaning that it must remain ON while the actuator is moving.
If the pause signal turns OFF while the actuator is moving, the actuator will decelerate to a stop.
The actuator will start moving when the signal turns ON again.
Use this signal as an interlock that actuates when an operator entry prohibition sensor or contact prevention
sensor is activated.
If the pause signal is not to be used, set parameter No. 15 (Pause input disable selection) to “1,” and
the actuator will move even when this signal is OFF.
(Note) When the “edge mode” is selected as the movement command type, you can change the target position
while the actuator is stopped with this signal turned OFF, as follows:
[1] Input a reset signal (RES) for 6 msec or more to cancel the remaining travel.
Next, turn ON the pause signal, and then input a movement command specifying the new target position.
(Example) Turn OFF the pause signal while the actuator is moving under direct position command 1.
The actuator decelerates to a stop.
o Turn OFF direct position command 1, and turn ON the reset signal for 6 msec or more.
o Turn ON the pause signal again, and input direct position command 2.
[2] After inputting a movement command specifying the new target position, turn ON the pause input.
(Example) Turn OFF the pause signal while the actuator is moving under direct position command 1.
The actuator decelerates to a stop.
o Turn OFF direct position command 1, and turn ON direct position command 2.
o Turn ON the pause signal again. The front end is recognized as the new target position.
