achieving high-performance speed regulation of the AM.
Integrated with the sensor-less vector control algorithm, the VFD can drive both AMs and
permanent-magnet SMs. As the core algorithm of vector control is based on accurate motor
parameter models, the accuracy of motor parameters affects vector control performance. It is
recommended to enter accurate motor parameters and autotune motor parameters before executing
vector control.
As the vector control algorithm is complicated, exercise caution before modifying vector control
function parameters.
