KPC (position controller gain factor)
The position controller gain factor for dynamic servo control (DSC) is transmitted via this
setpoint.
Transmission format: KPC is transmitted in the unit 0.001 1/s.
Range of values: 0 to 4000.0
Special case: When KPC = 0, the "DSC" function is deactivated.
Example:
A2C2A hex ≐ 666666 dec ≐ KPC = 666.666 1/s ≐ KPC = 40 1000/min.
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 10-9
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.
