SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
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.

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