Positioning with Digital Inputs						Home Position Return
	No.	Code	Function		Description
	PA05 ￿	*FTY	Feed length multi-		Needed here to scale the home position value to the physical coor-
			plication factor		dinate system when a home position offset (shift) has been set.
					Parameter value	Multiplication factor STM
					0	1
					1	10
					2	100
					3	1000
	PC02 ￿	*ZTY	Home position re-	Selects the home position return mode:
			turn mode	0: Proximity dog mode (DOG)
	PC03 ￿	*ZDIR	Home position re-	0: Incrementing counting of encoder pulses
			turn direction	1: Decrementing counting of encoder pulses
	PC04	ZRF	Home position re-	Sets home position return speed until first detection of the Z-phase
			turn speed	in [rpm].
	PC05	CRF	Creep speed	Speed for precise movement to home position in [rpm]
	PC06	ZST	Home position	Distance between the encoder home position (Z-phase) and the
			offset (shift)	physical home position in [µm]. Does not change the zero point of
				the physical coordinate system.
	PC07 ￿	*ZPS	Home position re-	The home position return stops when the Z-phase position is
			turn position value	reached.You can enter a non-zero coordinate for this position [in
				10STMµm] with this parameter.
	PD16 ￿	*DIAB	Input signal	Logical value for detection of the proximity dog signal (DOG):
			polarity	0: Active DOG on logical "0"
				1: Active DOG on logical "1"

Table 4-2:Parameter reference table

￿You must turn the power off and on again to activate this parameter.

Example:

In the following example the physical home position is at the position of the Z-phase of the encoder. However, we now want to assign a non-zero value in the physical coordinate system to this position.
