Speed actual value as a percentage of the default value (PNU 540).
The secondary speed actual value has a sign, so positive and negative values can be displayed.
The entire value range is utilised, i.e. the displayed speed lies in the range from −128 % to

+127 %. Higher speeds are limited to −128 % or +127 %.

and RSB are updated cyclically.
