Scaling and weighting
8.3 Weighting of acceleration data
The acceleration weighting is dened by the parameters listed in the following table.
This weighting describes the signicance of the LSB and the unit for all acceleration
parameters. All drive acceleration data (e.g.: reference values, actual values and limits)
are subject to the weighting set. If "no weighting" is selected via parameter S-0-0160,
the weighting factor and weighting exponent have no signicance. The acceleration
data are then subject to a weighting dened by other means.

8.3.1 Weighting, translatory acceleration data
Translatory weighting is selected via S-0-0160. The significance of the LSB for the
translatory acceleration data is defined by the following equation:
Significance LSB =
· S-0-0161 · 10
S-0-0162
On the selection of translatory preferred weighting, the weighting applies according to
the following table.

8.3.2 Weighting, rotary acceleration data
Rotary weighting is selected via S-0-0160. The significance of the LSB for the rotary
acceleration data is defined by the following equation:
Significance LSB =
