7.3 Vector control
Because asynchronous motors have the characteristics of high stage, nonlinear, strong coupling
and various variables, the actual control of the asynchronous motor is very difficult. Vector control is
mainly used to settle this problem with the theme of that divide the stator current vector into exciting
current (the current heft generating internal magnetic field of the motor) and torque current (the
current heft generating torque) by controlling and measuring the stator current vector according to
the principles of beamed magnetic field to control the range and phase of these two hefts. This
method can realize the decoupling of exciting current and torque current to adjust the high
performance of asynchronous motors.
Goodrive200A series VFDs are embedded speed sensor-less vector control calculation. Because
the core calculation of vector control is based on exact motor parameter models, the accuracy of
motor parameter will impact on the performance of vector control. It is recommended to input the
motor parameters and carry out autotune before vector running.
Because the vector control calculation is very complicated, high technical theory is needed for the
user during internal autotune. It is recommended to use the specific function parameters in vector
control with cautions.
