28 Setting the Position Switches

28.1 Outline

Position switches (PSW) are used as alternatives for the dog switches provided on the machine axis. Virtual dog
switches can be used by specifying axis names and conditions of virtual dog positions. This function outputs a signal to
the PLC interface when the machine reaches the specified area. The virtual dog switches are called "position switches"
(PSW).

Position switches (PSW1 - PSW24) are used to set virtual 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 specified area, a signal is output to the corresponding device of the PLC interface.
Whether the machine has moved into the area specified with the position switches can be judged at high speed by
setting parameters.
To judge the entry of the machine to the area, set parameters to select which type of position to be used for each position
switch from the following: commanded machine position or feed back position from encoder.
For description of the parameter, refer to "Alarm/Parameter Manual".
