Note:
The control signals, from the perspective of SIMODRIVE 611 universal are input signals and are
described in Chapter 6.4.3 (also refer to the index entry under Input signal, digital ...).
The percentage value for the velocity override is specified using this
control word.

The override normalization is defined using P0883 (override evaluation
PROFIBUS).

Notice
As the drive cannot rotate with Over = 0 %, then it is important for
PPO types 2, 4 and 5, that a practical value (greater than 0%) is in this
control word.
Negative values are interpreted as maximum value, as this control
word is viewed unsigned.
