Application Guide
Use this parameter to select the torque reference.
When the parameter P3.1.2.1 (Control Mode) is set to Torque control open loop, the motor torque is controlled. The motor speed
changes to agree with the actual load on the motor shaft.
The torque reference is scaled between the values of P3.3.2.2. and P3.3.2.3. When using a fieldbus protocol where the torque refer-
ence can be given in Nm units, set ProcessDataIn1 as the value to this parameter.

Location in the menu:
• INU application: P3.3.2.3
Use this parameter to set the maximum torque reference of the positive and negative values.
These parameters define the scaling of selected torque reference signal. For instance, the analog input signal is scaled between the
Torque Reference Minimum and the Torque Reference Maximum.
