The actual drive active power is displayed using this status word.
The active power is calculated from the speed actual value and the ac-
tual torque setpoint. Contrary to the torque and power limits, in this
case, the current limiting is not taken into account.

The drive torque is displayed using this status word.
The normalization of Msoll is defined (from SW 4.1) using P0882 (eva-
luation, torque setpoint PROFIBUS).

The reference torque is displayed in P1725 (normalization, torque
setpoint).
The torque value is smoothed via P1252 (transition frequency, torque
setpoint smoothing).
