Exam ple:
In the fol low ing exam ple the phys i cal home posi tion is at the posi tion of the Z-phase of the
encoder. How ever, we now want to assign a non-zero value in the phys i cal coor di nate sys tem to
this posi tion.

The home po si tion re turn stops when the Z-phase po si tion is
reached.You can en ter a non-zero co or di nate for this po si tion [in
