Appendix 1.21.1 Outline

Position switches (PSW) are used as alternatives for the dog switches provided on the machine axis. Imaginary dog
switches, with axis names and imaginary dog coordinates preset by parameters, output a signal to the PLC
interface when the machine reaches the switch area. The imaginary dog switches are called position switches
(PSW).

Position switches (PSW1 - PSW24) are used to set imaginary dog coordinates (dog1 and dog2) on the coordinate
axes, whose names are preset with <axis>, as alternatives for the dog switches provided on the machine axis.
When the machine reaches the switch area, a signal is output to the corresponding device of the PLC interface.
