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.
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 399.
This parameter is read-only.
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 30.19 Minimum torque
Minimum torque reference.
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 30.20 Maximum torque
