Notes
This parameter must be set independently for each servo.
The significance of most of the following axis servo parameters is directly
related to the selection made here.
Function
Enter the pitch of the lead screw for the axis being configured. Pitch refers
to the number of inches or millimeters between each thread.
For example, a common lead for machine tools in the U.S. is 5 threads per
inch. The lead screw thread pitch in this case would be:
1 inch
----------- = .20 inch
5 threads
Refer to figure 7.13 for an illustration of the mechanical configuration of a
typical axis.
