Home Offset (CP-31)
The Home Offset parameter allows you to offset the “Home” position
and relocate it somewhere other than the sensor.
If CP-24 is set at “1” (edge based), measure the distance from the
sensor to the desired position of “Home”. Enter that E.U. amount in
CP-31.

If CP-24 is set at “2” (center based), measure the distance from the
sensor to the center. Enter that E.U. amount in CP-31. The
M-Traverse will make a transparent, internal calculation and position
“Home” at a distance that is CP-31 minus 1/2 of the traverse length.
The position of “Home” will change to correspond with any changes in
the traverse length.

NOTE: Since the “Home” position calculations are dependent on the
Traverse Length (CP-02, CP-04, CP-06, CP-08) parameter and the Engineer-
ing Units (CP-15) parameter, those values must have already been entered
prior to entering a value in CP-31. To enter these parameters, refer to the
Operations: Control Parameters section.
