- / real32Displays the final torque reference given to the torque
controller in percent. This reference is then acted upon
by various final limiters, like power, torque, load etc.

26.1
See the control chain diagrams on pages 655 and 656.
This parameter is read-only.
- / -Torque reference for torque control. For scaling, see
parameter 46.3.
-1600.0 ... 1600.0 %
- / real32Displays the final torque reference (in percent of motor
nominal torque) given to the DTC core, and comes after
frequency, voltage and torque limitation.

This parameter is read-only.
- / -Torque reference for torque control. For scaling, see
parameter 46.3.
-1600.0 ... 1600.0 %
-300.0 % / real32Defines the minimum torque reference. Allows for local
limiting of the torque reference before it is passed on
Minimum torque ref26.8
to the torque ramp controller. For absolute torque
limiting, refer to parameter 30.19 Minimum torque 1.
- / -Minimum torque reference. For scaling, see parameter
46.3.
-1000.0 ... 0.0 %
300.0 % / real32Defines the maximum torque reference. Allows for local
limiting of the torque reference before it is passed on
Maximum torque ref26.9
to the torque ramp controller. For absolute torque
limiting, refer to parameter 30.20 Maximum torque 1.

Zero / uint32Selects torque reference source 1.
Two signal sources can be defined by this parameter
and 26.12 Torque ref2 source. A digital source selected
Torque ref1 source26.11
by 26.14 Torque ref1/2 selection can be used to switch
between the two sources, or a mathematical function
(26.13 Torque ref1 function) applied to the two signals
to create the reference.
