Primarily used for controlling and adjusting the speed and torque of permanent magnet synchronous motors, it features high accuracy in self-tuning motor parameters, high steady-state speed precision, a wide speed regulation range, significant low-speed torque, and minimal torque pulsation. It achieves complete or semi-separation of V/F control, supports both open-loop and closed-loop controls, accommodates various PG cards, and comes standard with RS485 communication.
