Description
Settings for the torque reference chain.
See the control chain diagrams on pages
Displays 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.
See the control chain diagrams on pages
This parameter is read-only.
Torque reference for torque control. For scaling, see
parameter 46.3.
Displays the final torque reference (in percent of motor
nominal torque) given to the DTC core, and comes after
frequency, voltage and torque limitation.
See the control chain diagram on page 754.
This parameter is read-only.
Torque reference for torque control. For scaling, see
parameter 46.3.
Defines the minimum torque reference. Allows for local
limiting of the torque reference before it is passed on
to the torque ramp controller. For absolute torque
limiting, refer to parameter
Minimum torque reference. For scaling, see parameter
46.3.
Defines the maximum torque reference. Allows for local
limiting of the torque reference before it is passed on
to the torque ramp controller. For absolute torque
limiting, refer to parameter
Maximum torque reference. For scaling, see parameter
46.3.
Selects torque reference source 1.
Two signal sources can be defined by this parameter
and 26.12 Torque ref2 source. A digital source selected
by 26.14 Torque ref1/2 selection
between the two sources, or a mathematical function
(26.13 Torque ref1 function) applied to the two signals
to create the reference.
