An example of each option is given on the following pages.

Option 1 Example

When these parameters are set, the axis moves one revolution of the

The problem is reported to the SLC processor.

IMPORTANT

This configuration is typical for a unidirectional axis

(i.e., axis that only moves in one direction).
