Motor Control Method
0: Constant Torque
1: Reduced Torque (Variable Torque)
2: Sensorless Vector Control
Reduced torque is effective for fan or pump application which do not require high torque
at low frequency. By reducing the output voltage, increased efficiency, lower noise, and
lower vibration.
For Sensorless Vector method, per specified output voltage, current, motor parameters,
motor rpm, the corresponding torque value is calculated. At very low frequency up to 0.5
Hz, high torque operation is possible
