IDN43 Velocity Polarity Parameter
The velocity polarity parameter is used to switch the polarities of velocity data. Polarities
are not switched internally but externally, this means on the in- and output of a closed
loop system.
( sercos
are not changed).
The motor shaft turns clockwise when there is a positive velocity setpoint and no inver-
sion.

IDN44 Velocity Data Scaling Type
Defines the scaling options for all velocity data.
The scaling types which are supported are:
If preferred rotational scaling is selected, the velocity scaling factor (IDN45) will set to 1
and the velocity data scaling exponent (IDN46) will set to -4 (refer to IDN45 and 46).
