Homing on the Fly

2.12.4.3
Homing on the fly adjusts Actual Position and Demanded Position when passing the home sensor, thus refreshing the home position
while running, without affecting the ongoing movement.
Homing on the fly can be used in all operating modes as a one-time homing maneuver after power-up, instead of having to execute
a separate one-time homing function before starting. Alternatively it can be used as a continuous function to avoid position drifting.
Homing on the fly is activated as a background task by selecting the required function with parameter 5.17.2.15 Homing On The Fly. The
following selections are available:
1st time after power-up
