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.

Description

PA05

햲

*FTY

Feed length multi-
plication factor

Needed here to scale the home position value to the physical coor-
dinate system when a home position offset (shift) has been set.

PC02

햲

*ZTY

Home position re-
turn mode

Selects the home position return mode:
0: Proximity dog mode (DOG)

PC03

햲

*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
offset (shift)

Distance between the encoder home position (Z-phase) and the
physical home position in [µm]. Does not change the zero point of
the physical coordinate system.

PC07

햲

*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.

*DIAB

Input signal
polarity

Logical value for detection of the proximity dog signal (DOG):
0: Active DOG on logical "0"
1: Active DOG on logical "1"
