ESCRIPTION
ClearPath will make an incremental move when the state of Input A
changes. If automatic homing is on, ClearPath will seek for the home
switch connected to Input B the first time it is enabled after power up, or,
if desired, each time it is enabled.
What is 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 move is launched.
Assert the Enable Input to energize the motor. ClearPath can be set up to
perform an optional homing routine upon enable (home-to-switch only in
this mode). Change the state of Input A to launch each move at the user-
defined speed and acceleration. Briefly pulse the Enable input to execute
the next move at the alternate speed limit.

UNCTIONS
Enable Input -
Asserting this input energizes the motor shaft. A short
pulse (user-definable) on this input tells ClearPath to use the alternate
speed limit setting for the next move. (A "pulse" is a momentary
interruption of current into the Enable input.)
Input A -
Turning this input on (or off, if desired) sends the position
increment.
Input B -
This input is connected to the home switch/sensor. Its function
is defined in the homing setup dialog.
Output (HLFB) -
See HLFB section for available modes.
Notes:
•
Send incremental moves by turning Input A either on or off
(this is user settable).
