Use of the “Upper mapping end” parameter
The following chapter illustrates the use of the parameter “upper mapping end” both graphically
and by means of examples:
a) Delivery state
In the delivery state (“DS”), the actual position is exactly in the middle of the positioning range.
There is a safety margin of three rotations at the output shaft at both the lower and upper ends of
the positioning range.
Positioning runs that extend into these safety margins are rejected by the device with the error
“Incorrect target value”.
In the delivery state, the values from the following table result for the upper mapping end and the
lower and upper limits:

Positioning range symmetrical to 0
Starting from this state, the maximum possible positioning range can now be shifted upwards or
downwards as required.
It is important to note that after the device has been installed, the available positioning range may
not be sufficient in one of the two
directions. The parameter “upper mapping end” now allows you
to reduce the positioning range in one direction and increase it in the other direction.
