Home Marker Distance

These parameters are read only. They correspond to the current home marker

distance. These parameters will contain the distance to marker calculated

when the axis stopped after the home switch went false during the last

homing operation.

Home Marker Tolerance

These parameters are read only. They correspond to the current home marker

tolerance. These parameters will contain the tolerance value at power turn on

and will represent 3/8 of an electrical cycle of the feedback device converted

to current axis programming units (inch/metric, degrees or revolutions).

Paramacro parameters are provided by on the control to allow a means of

communicating values between the PAL program and the part program.

This is done by assigning values to specific paramacro parameters or PAL

flags. They are:

Input parameters: Use these parameters to transfer data from PAL to the
part program.

Output parameters: Use these parameters to transfer data from the part
program to PAL. Some applications may, however, use the output flags

to transfer data from PAL to the part program as needed.
