Assert the Enable Input to get started. Once enabled, ClearPath reads th
state of Inputs A and B and
indicated. For example, if Input A is high and Input B is low
ClearPath will ramp to “Velocity 2”. Change to aq different velocity by
changing Inputs A and B.

Tip:
Setting one of the programmable velocities to zero (Velocity 3 in the example
at right) provides a convenient way to stop the motor via the ClearPath inputs.

Notes:
•
As soon as a new velocity command is received by ClearPath—as
happens when Inputs A and/or B are changed—ClearPath
immediately ramps to the new target velocity without delay.
•
For a convenient way to command ClearPath to stop, set one of
the velocity settings to zero. We did this with “Velocity 3” in the
table above.
