14. Indexing Axis Position Switch
14.1 Outline of Function
(Note) These parameters are used only with the G64T.
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).
The position switch for the indexing axis is set on this screen.

The PLC position output signal turns ON
when the machine reaches the range
between the imaginary dog position 1 and
imaginary dog position 2.

(Note) If the imaginary dog positions 1 and 2 are both set to “0”, the signal will not be output to the PLC
interface.
