Vector control with encoder

Benefits of vector control with an encoder:
S The speed can be controlled right down to 0 Hz (standstill)
S Constant torque in the rated speed range
S Compared with speed control without an encoder, the dynamic response of
drives with an encoder is significantly better because the speed is measured
directly and integrated in the model created for the current components.
S Higher speed accuracy
