Activate traversing range adaptation (from SW 3.1)

Description For large traversing ranges, the traversing range adaptation must be
activated in order to maintain the accuracy.
If traversing only in one direction, a greater traversing range applies.
For example, this is possible if, when traversing in the positive direc-
tion, the reference point is set again and then the axis continues to
move in the positive direction and this scenario is repeated. This condi-
tion applies both for rotary axes and linear axes. The average value of
all traversing distances is decisive for traversing in one direction.

The traversing range for linear axes is limited to an adaptation band
ADB (refer to the calculation of ADB).
The adaptation band ADB on a rotary axis is identical with the maxi-
mum permissible value of P1 (this depends on P2 and P3 and is
described in the parameter description of P1).
Certain parameters are limited to the adaptation band applicable for the
axis type. A rotary axis is involved if P1 > 0, a linear axis if P1 = 0.
Calculating the adaptation band ADB of a linear axis:
– SIMODRIVE POSMO A – 75 W
) S 1.5 S P2[mm] / (816 S |P3|)

ADB [mm] = (2
– SIMODRIVE POSMO A – 300 W
) S 1.5 S P2[mm] / (4096 S |P3|)

ADB [mm] = (2
The adaptation band, independent of the calculation value, has a
maximum value of 200000 mm.
