1PosInc/Analog
4.6 Functions of the 1PosInc/Analog
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
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
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.

Meaning
If you adjust the direction, this results in
the polarity reversal of your drive
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
