Torque Control With Fixed Torque Setpoint - Siemens SINAMICS V90 Operating Instructions Manual

The analog voltage from the analog input 2 corresponds to a parameterized torque value
scaling (p29041[0]). If p29041[0] = 100%, analog input voltage of 10 V corresponds to rated
torque; if p29041[0] = 50%, the analog input value of 10 V corresponds to 50% of the rated
torque.
Parameter
p29041[0]
Note
The value of analog input 2 can be monitored through parameter p29351.
Offset adjustment for analog input 2
Offset exists for the input voltage from the analog input 2. The motor can run at a very low
speed even the current input voltage is 0 V. You have 2 methods to adjust such offset:
● Automatic adjustment with BOP function: refer to "Adjusting AI offsets (Page 157)" for
details.
● Manual input of an offset value (p29042)
