PC04

ZRF

Home position re-

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].

*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
