P3.3.1.7 KEYPAD CONTROL REFERENCE SELECTION (ID 121)
Use this parameter to select the reference source when the control place is keypad.
P3.3.1.8 KEYPAD REFERENCE (ID 184)
Use this parameter to adjust the frequency reference on the keypad.
P3.3.1.9 KEYPAD DIRECTION (ID 123)
Use this parameter to set the rotation direction of the motor when the control place is
keypad.
P3.3.1.10 FIELDBUS CONTROL REFERENCE SELECTION (ID 122)
Use this parameter to select the reference source when the control place is Fieldbus.
The selection of the application with parameter P1.2 Application gives the default value. See
the default values in Chapter 12 Appendix 1.
10.4.2 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. P3.3.2.7 (Torque Control Frequency Limit) controls the motor speed limit.

P3.3.2.1 TORQUE REFERENCE SELECTION (ID 641)
Use this parameter to select the torque reference.
The torque reference is scaled between the values of P3.3.2.2. and P3.3.2.3.
If you use a fieldbus protocol where the torque reference can be given in Nm units, you must
set ProcessDataIn1 as the value to this parameter.
P3.3.2.2 TORQUE MINIMUM REFERENCE (ID 643)
Use this parameter to set the minimum torque reference.
This parameter defines the minimum torque reference of the positive and negative values.
