Home Parameters
Chapter 5
5-11
Notes
This parameter must be set independently for each axis.
This parameter is not used for axes that use distance coded marker linear
feedback devices.
Function
This parameter specifies the distance from the encoder marker to the
desired home position. The control moves this distance plus the distance
to the encoder marker after the home limit switch changes from “ON”
to “OFF.”
Use this parameter to define a precise mechanical home position without
adjusting the home limit switch or encoder positions.

or
--39370.07835 to 39370.07835 in.
Notes
Use this parameter to compensate for mechanical changes that otherwise
would have relocated the home position for an axis.
For example, it may be necessary to move the encoder or home limit
switch to avoid the undesirable condition mentioned in the Caution note on
page 5-7. Use the Home Calibration parameter to compensate for this
mechanical change.
