Appendix 1.16.1 Outline

The position switch (PSW) is used as an imaginary dog switch by assigning an axis name and coordinate values
that indicate the imaginary dog position to be used instead of the dog switch on the machine axis. When the
machine reaches the imaginary dog position, a signal is output to the PLC interface. This imaginary dog switch is
called the position switch (PSW).

Instead of the dog switch provided on the machine axis‚ the coordinate values indicating imaginary dog positions
(dog1 and dog2) on the coordinate axis of the axis name preset with axis are set with the position switches (PSW1
– PSW16). When the machine reaches the position‚ the signal is output to the device corresponding to the PLC
interface.

Description
A signal is output between dog1
and dog2.
A signal is output between dog1
and dog2.
If dog1 equals dog2‚ the dog1
position triggers a signal.
