You can read the status of the OUT digital output from the feedback interface, with a delay
that corresponds to the updating rate.

Figure 4-8 Schematic Diagram of the Unipolar Control of a Drive
Changing the Voltage for Rapid Feed and Creep Feed
The default setting for rapid feed is 10 V and the default setting for creep feed is 1 V. You
can only change these settings using JOBs 5 and 6.
After the 1PosInc/Analog starts up or after parameter assignment with changed parameters,
the values are accepted from the parameters.
You can set a voltage between 0 V and 11.7589 V (including overrange) in S7 analog value
format (you will find a detailed explanation in the
Distributed I/O Device manual).
If you have selected a greater voltage for creep feed than for rapid feed, there will be
acceleration at the switchover point from rapid feed to creep feed.

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
