ALREADY ON HOME SWITCH: If a homing sequence is initiated and the home switch is already activated, the
drive will “back off” of the home switch and then proceed with the normal homing sequence. If the homing type is
either “Home Positive with Backup” or “Home Negative with Backup,” an abbreviated homing routine is run instead.
