SOURCE - Limits and Homing _ Configuring Signals
To set up and wire 24V limit/home switches, follow the steps outlined below.
In the example above, motor 0, 1, and 2 home switches are enabled. All of them are wired normally closed. The device and input name for motor 0 is HiCON [P11] Input1 (X1). Since the switches for each motor are wired in series, the motor ++ and motor -- signals lower down in the list would also have the same corresponding device and input names. Manually trigger each limit switch and make sure they disable Mach before continuing.
