Application Notes
Limit Switch Set up
1.
Move the load to a position between the two decel switches (“A” in
2.
Select the switches in [Digital In1-6 Select]. If switches are only
used on one end of travel, simply keep the load off of both switches
when selecting in [Digital In1-6 Select].
If the set up is done incorrectly, the application will not move or will
move at an incorrect (slower) speed. This can be corrected by selecting
“Not Used” for both limit switches in [Digital In1-6 Select]. Then, move
the load between the Decel Switches and select the limit switches again
in [Digital In1-6 Select].
Important:
When properly set up, the drive will remember its location
during power cycles (or power loss) unless the load is
manually moved during power down conditions. If this
occurs, simply reset the feature using the procedure above.
