3.6 I/O Signals for PIO Pattern 1 [3 Points] (Air Cylinder)
The following description assumes that the actuator is used in place of an air cylinder.
The number of positioning points is limited to three, but a direct command input and a position complete output are
provided separately for the target position in line with the conventional practice of air cylinder control.
Caution: The factory setting is “8 points,” so set parameter No. 25 to “1.” The pause signal can be disabled in
parameter No. 15.
(Note) *STP and *ALM are always ON.
3.6.1 Explanation of I/O Signals
Category Signal name
Signal
abbreviation
Function overview
Rear end move ST0 The actuator starts moving to the rear end at the rise edge of the signal.
Front end move ST1 The actuator starts moving to the front end at the rise edge of the signal.
Intermediate
point move
ST2
The actuator starts moving to the intermediate point at the rise edge of the
signal.
*Pause *STP ON: The actuator can be moved, OFF: The actuator decelerates to a stop
Input
Alarm reset RES This signal resets the alarm output signal.
Rear end
complete
PE0 The signal turns ON when the actuator completes moving to the rear end.
Front end
complete
PE1 The signal turns ON when the actuator completes moving to the front end.
Intermediate
point complete
PE2
The signal turns ON when the actuator completes moving to the intermediate
point.
Output
*Alarm *ALM
This signal remains ON while the controller is operating properly, and turns
OFF when an alarm generates.
(Note) The signal remains ON while the motor drive power is cut off.
