Scaling and weighting
8.2 Weighting of speed data
The speed weighting is defined by the parameters listed in the following table. This
weighting describes the significance of the LSB and the unit for parameter S-0-0040 as
well as all other speed parameters.
All drive speed data (e.g.: reference values, actual values and limits) are subject to the
weighting set. If "no weighting" is selected via parameter S-0-0044, the weighting factor
and weighting exponent have no significance. The speed data are then subject to a
weighting defined by other means.

8.2.1 Weighting, translatory speed data
Translatory weighting is selected via S-0-0044. The significance of the LSB for the
translatory speed data is defined by the following equation:
Significance LSB =
Zeiteinheit
Wegeinheit
· S-0-0045 · 10 S-0-0046
On the selection of translatory preferred weighting, the weighting applies according to
the following table.

8.2.2 Weighting, rotary speed data
The rotary weighting is selected via S-0-0044. The significance of the LSB for the rotary
speed data is defined by the following equation:
Significance LSB =
