*FTY Feed length multi-
plication factor Needed here to scale the home position value to the physical coor-
dinate system.
PC02

*ZTY Home position re-
turn mode Selects the home position return mode:
A: Dogless Z-phase reference mode
PC03
ቢ
*ZDIR Home position re-
turn direction 0: Incrementing counting of encoder pulses
1: Decrementing counting of encoder pulses
PC04 ZRF Home position re-
turn speed Sets home position return speed until first detection of the Z-phase
in [rpm].
PC05 CRF Creep speed Speed for precise movement to home position in [rpm].
PC06 ZST Home position off-
set (shift) Distance between the encoder zero point (Z-phase) and the physi-
cal home position in [µm].
PC07
ቢ
*ZPS Home position re-
turn position value The home position return stops when the Z-phase position is
reached.You can enter a non-zero coordinate for this position [in
10
STM µm] with this parameter.
