ESCRIPTION
Send a trigger pulse to tell ClearPath to move a user-defined distance from
its current position. Send multiple, quick trigger pulses to tell ClearPath to
travel a multiple of any distance in one smooth, uninterrupted move.
Incremental Positioning
An incremental move is referenced to its own starting position, not to an
absolute “home” reference position. So, if the incremental move distance
is set to +1000 counts, the shaft will move +1000 counts from its current
position each time a trigger pulse is received.
Assert the Enable Input to energize the motor. ClearPath can be set to
perform an optional homing routine (home-to-switch only in this mode).
Incremental move distance is selected with Input A. Pulsing the
Enable/Trigger Input launches each move.

UNCTIONS
Enable Input -
Asserting this input energizes the motor shaft.
Input A -
This input selects which of the two defined position increments
to send upon a trigger pulse.
Input B -
This input is connected to the home switch/sensor. Its function
is defined in the homing setup dialog. Home switch polarity can be
inverted if desired.
Output (HLFB) -
See HLFB section for available modes.
Notes:
•
A trigger pulse is required to launch each incremental move.
Move distance is selected with Input A.
•
To create a longer continuous move, you can send multiple
trigger pulses and ClearPath will automatically “chain” the
move increments together to form a single seamless move.
Note: To successfully “chain” move increments, the burst of
trigger pulses must be sent rapidly. They must be received by
