Description
Needed here to scale the home position value to the physical coor-
dinate system.
Selects the home position return mode:
A: Dogless Z-phase reference mode
0: Incrementing counting of encoder pulses
1: Decrementing counting of encoder pulses
Sets home position return speed until first detection of the Z-phase
in [rpm].
Speed for precise movement to home position in [rpm].
Distance between the encoder zero point (Z-phase) and the physi-
cal home position in [µm].
The home position return stops when the Z-phase position is
reached.You can enter a non-zero coordinate for this position [in
STM
10 µm] with this parameter.
