MOMRED (torque reduction) 
This setpoint can be used to reduce the torque limit currently active on the drive. 
When you use manufacturer-specific PROFIdrive telegrams with the MOMRED control word, 
the signal flow is automatically interconnected up to the point where the torque limit is 
scaled.

Figure 9-7  MOMRED setpoint 
MOMRED specifies the percentage by which the torque limit is to be reduced. This value is 
converted internally to the amount by which the torque is to be reduced and normalized via 
p1544.
