Goodrive350 series high-performance multifunction VFD
Basic operation guidelines
-55-
asynchronous motor and permanent-magnet synchronous motor simultaneously. As the core
algorithm of vector control is based on accurate motor parameter model, the accuracy of motor
parameters will impact the control performance of vector control. It is recommended to input accurate
motor parameters and carry out motor parameter autotuning before vector operation.
As vector control algorithm is complicated, you should be cautious of regulation on dedicated function
parameters of vector control.
