Parameters Meaning Value range Default setting
Reference point run and evaluation of the reference signal
Reference signal This parameter defines the relevant
switch or the combination of switch
and zero mark.
• Reference switch and zero
mark
• Reference switch
• Zero mark
Reference switch and
zero mark
Reference switch Relevant in the case of reference
signal:
• Reference switch and zero mark
• Reference switch
This parameter defines the
referencing direction in which the
switch must be traversed.
• Reduction cam towards
minus
• Reduction cam towards plus
• Minus limit switch
• Plus limit switch
Reduction cam
towards minus
Start direction of the
reference point run
• Plus
• Minus

Drive
Adapt direction If you adjust the direction, this results
in the polarity reversal of your drive
• Off
• On
Off
Function DO Output:
Your drive is controlled by the analog
output using ±10 V.
You control the DO digital output
using the CTRL_DO control bit.
Direction:
Your drive is controlled by the analog
output using 0 V to 10 V.
The direction for your drive is
specified by the 1PosInc/Analog via
the DO digital output.
Plus direction: DO = 1
Minus direction: DO = 0

Output
Switch-off Use this parameter to determine the
course of the voltage after the switch-
off point.
Directly: The voltage is set directly to
0 V at switch-off point.
Ramp: As of switch-off point, voltage
is reduced to 0 V using the ramp.

Directly
Switch-off difference Defines the distance from the
destination at which the drive is
slowed down from creep feed to 0.
If the switch-off difference ≥ the
switchover difference, there is no
switchover point. There is no
slowdown from rapid feed to creep
feed.
0 - 65 535 100
Switchover difference Defines the distance from the
destination at which the drive is
slowed down from rapid feed to
creep feed.
0 - 65 535 1000
