7.2 Weighting of velocity data
The velocity weighting is defined by the parameters listed in the following table. All
velocity data of the drive (e.g.: setpoint, actual and limit values) are subject to the preset
weighting. If “No weighting“ is selected via parameter S-0-0044, the weighting factor
and weighting exponent are irrelevant. The velocity data is then subject to a differently
defined weighting.

7.2.1 Weighting of translatory velocity data
Translatory weighting is selected via S-0-0044. The significance of the LSB of the transla-
tory velocity data is defined by the following equation:
LSB significance =

· S-0-0045•10
S-0-0046
When translatory preferential weighting is selected, the weighting as per the following
table applies.
