2.4 V/F CONTROL
2.4.1 AUTOMATIC SETTING OF WORKING VOLTAGE/FREQUENCY
“V/f control” manages the an asynchronous motor without feedback.
This type of control has a good dynamic performance also in flux weakening area (4-5 times base
frequency) and it’s able to start the motor also with high load (2 times the nominal motor torque), but
