A Drive for Permanent Magnet (PM) Motors High-Performance Field-oriented Control The C2000 is a dual mode drive to control both an induction motor and permanent magnet motor. The dynamic response of a PM motor provides precise control of position, speed and torque The FOC+PG mode of C2000 Series can output 150% of starting torque at extremely low speeds for precise and stable speed control.
