7.4.3.10 Home return

FP0R User's Manual
This instruction performs a home return according to the parameters in the
specified DUT.
After a drive system has been switched on, there is a difference between
the internal position value (elapsed value) and the mechanical position of
the axis; this difference cannot be predetermined. The internal value must
be synchronized with the actual position value of the axis. This is done by
means of a home return, during which a position value is registered at a
known reference point (home).
