Description
Needed here to scale the home po si tion value to the phys i cal co or -
di nate sys tem.
Se lects the home po si tion re turn mode:
A: Dogless Z-phase ref er ence mode
0: In cre men ting count ing of en coder pulses
1: Dec re ment ing count ing of en coder pulses
Sets home po si tion re turn speed un til first de tec tion of the Z-phase
in [rpm].
Speed for pre cise move ment to home po si tion in [rpm].
Dis tance be tween the en coder zero point (Z-phase) and the phys i -
cal home po si tion in [µm].
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 position [in
STM
10 µm] with this parameter.
