Functional Description
When in Phase control, the Phase Inch function block may be used to advance or retard the relative position
on the slave axis with respect to the master axis. This is achieved by feeding extra counts into the position
calculator at a rate given by RATE in units per second.
ADVANCE and RETARD are usually linked to operator controlled, momentary-action push buttons
