3.6.3 Details of Output Signals
„ Completion of each position (PE0 to PE2)
These signals indicate that the target position corresponding to each movement command (ST0, ST1 or ST2) has
been reached, in the same way the reed switch signal does for an air cylinder.
Output signal Meaning of the signal
Rear end complete (PE0)
The actuator has reached and stopped at the rear end (target position set in position
No. 0).
Front end complete (PE1) The actuator has reached and stopped at the front end (target position set in position
No. 1).
Intermediate point complete
(PE2)
The actuator has reached and stopped at the intermediate point (target position set in
position No. 2).
(Note) Although these signals remain OFF while the motor drive power is cut off, once the power is reconnected the
signal will return to the ON state if the current actuator position is within the in-position band over the target
position. If the actuator is positioned outside the in-position band, the signal will remain OFF.
„ Alarm (*ALM)
This signal remains ON while the controller is operating properly, and turns OFF when an alarm generates. Monitor
the OFF state on PLC and provide appropriate safety measures for the entire system.
Refer “9. to Troubleshooting” for alarm details.
