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.

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

Selects the home position return mode:
0: Proximity dog mode (DOG)
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 home position (Z-phase) and the
physical home position in [µm]. Does not change the zero point of
the physical coordinate system.
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.
Logical value for detection of the proximity dog signal (DOG):
0: Active DOG on logical "0"
1: Active DOG on logical "1"
