4.4.8 Zone

Signal

This signal is output (becomes “1”) when the current position of the actuator is inside the set zone, and it can be
used in the following application:
[1] Interlock signal to prevent interference with peripheral equipment
[2] Trigger signal to reduce the tact time for peripheral equipment
[3] Judgment of work not being contacted during push & hold operation
[4] End-point

determination

constant pitch feeding of work placed in alignment

(Note) In the constant pitch feeding, the “Position” field of the position table indicates the relative amount

but the zone setting establishes the absolute coordinate from the home position.

* The zone signal is output to the zone status register (address 9013H).

It becomes “1” when the current position is inside the zone range or becomes “0” when the current
position is outside the zone range.
The signal becomes valid after the completion of home return. It is valid even when the servo is OFF,
provided that home return has been completed.
