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)
