P3.3.2.2 TORQUE MINIMUM REFERENCE (ID 643)
Parameter P3.3.2.2 defines the minimum torque reference of the positive and negative
values.
P3.3.2.3 TORQUE MAXIMUM REFERENCE (ID 642)
Parameter P3.3.2.3 defines the maximum torque reference of the positive and negative
values.
These parameters define the scaling of selected torque reference signal. For instance, the
analogue input signal is scaled between the Torque Reference Minimum and the Torque
Reference Maximum.

P3.3.2.7 TORQUE CONTROL FREQUENCY LIMIT (ID 1278)
In the torque control mode, the drive output frequency is always limited between
MinFreqReference and MaxFreqReference (P3.3.1.1 and P3.3.1.2).
You can also make the selection of 2 other modes with this parameter.
Selection 0 = Pos/Neg Freq Limits, that is, the positive/negative frequency limits.
The frequency is limited between Positive Frequency Reference Limit (P3.3.1.3) and Negative
Frequency Reference Limit (P3.3.1.4) (if these parameters are set lower than the value of
P3.3.1.2 Maximum Frequency).
