ESCRIPTION
This mode is mainly intended to be used in two-position back and forth
applications (like replacing a pneumatic cylinder). Use ClearPath digital
inputs to spin the shaft CW or CCW. Wire position sensors or switches in
series with ClearPath inputs to make an inexpensive two position
actuator.
Place sensors at opposite ends of your motion path and wire them into the
appropriate ClearPath inputs. See illustration below.
Assert the Enable Input to energize the motor. Apply User Commands to
start motion. ClearPath moves CW or CCW until it interrupts a sensor. It
then holds position until you issue a new User Command in the opposing
direction. See table below for Input states and timing details.
