Each motor has a limit switch signal for positive and negative overtravel. These signals must be enabled and mapped
to the appropriate I/O point to work. The signals are called Motor # ++ and Motor # --, where # is the motor number.
The I/O point that is mapped here needs to be the one that the limit switch for that motor is wired into. The same input
can be used for both ends of an axis, if the machine is wired in that way. When a limit switch is triggered, it will disable
the machine.
Limit Switches
If these signals are not mapped correctly, the machine will not stop motion or disable when a limit switch is
triggered.
