5.2.5 Pause
The actuator can be paused during movement using an external input signal (*pause).
The pause signal uses the contact B logic (always ON) to ensure safety.
Turning OFF the *pause input will cause the actuator to decelerate to a stop, while turning it ON will allow the actuator
to complete the remaining operation.
(Note) The deceleration becomes the value set in the “Deceleration” field of the position table for the position
number corresponding to the current positioning operation.
5.2.6 Zone Signal Output
The zone signal is output when the actuator enters the specified zone during movement. Accordingly, this signal can
be used for the following purposes:
[1] As a trigger signal for peripheral equipment to reduce the tact time
[2] To prevent contact with peripheral equipment
[3] As a “simple ruler” in push & hold operation
The zone in which the signal turns ON varies depending on the PIO pattern
„ PIO pattern = 0 (8 points) or 2 (16 points: setting by zone boundary parameters)
The zone in which the zone signal turns ON is set by parameters.
Parameter No. 1 = Zone boundary+, parameter No. 2 = Zone boundary–
„ PIO pattern = 3 (16 points: setting in zone fields in the position table)
The zone in which the zone signal turns ON is set by the “Zone–” and “Zone+” fields of the position table.
