Group 26: Torque reference handling
26.01 TorqSel (torque selector)
Torque reference selector:
0 = Zero
zero control, torque reference = 0
1 = Speed speed control, default
2 = Torque torque control
3 = Minimum minimum control: min [TorqRef1 (2.08), TorqRef2 (2.09)]
4 = Maximum maximum control: max [TorqRef1 (2.08), TorqRef2 (2.09)]
5 = Add add control: TorqRef1 (2.08) +TorqRef2 (2.09), used for window control
6 = Limitation limitation control: TorqRef1 (2.08) limits TorqRef2 (2.09). If TorqRef1 (2.08) = 50%, then
TorqRef2 (2.09) is limited to
±
50%.
The output of the torque reference selector is TorqRef3 (2.10). The currently used control mode is displayed in
CtrlMode (1.25). If the drive is in torque control, AuxStatWord (8.02) bit 10 is set.
Note:
TorqSel (26.01) is only valid, if TorqMuxMode (26.04) = TorqSel2601.

26.02 LoadComp (load compensation)
Load compensation - in percent of MotNomTorque (4.23) -added to TorqRef3 (2.10). The sum of TorqRef3
(2.10) and the LoadComp (26.02) results in TorqRef4 (2.11).
Note:
Since this torque offset is added, it must be set to zero prior to stopping the drive.

26.04 TorqMuxMode (torque multiplexer mode)
TorqMuxMode (26.04) selects a pair of operation modes. The change between operation modes is done by
means of TorqMux (26.05). Torque reference multiplexer:
0 = TorqSel2601
operation mode depends on TorqSel (26.01), default
1 = Speed/Torq operation mode depends on TorqMux (26.05):
−
binary input = 0
⇒
speed control (1)
−
binary input = 1
⇒
torque control (2)
