You provide standard step and direction signals and ClearPath faithfully
follows them. Use the included RAS (Regressive Auto Spline) feature to
smooth the motion profile. This mode is great for replacing stepper motor
and drive systems with one compact device that costs less and does more.

Assert the Enable Input to energize the motor. Then, supply standard step
and direction pulses to Inputs A and B to command motion. This model
requires step and direction signals from an external indexer, controller, or
similar.
