Feature: 1. PID Control: PID control unit has excellent performance, fast operation speed, short response time, and can quickly achieve the equilibrium value. 2. Voltage Stabilization: Built in three phase high precise automatic AC voltage stabilizer, when the grid voltage changes by 10%, can automatically adjust and keep the output voltage constant. 3. Multi Control Modes: Features VF control, non inductive vector control, switching flux vector control, open loop torsion control, PG vector control, etc., support online switching of torsion and speed control. 4. Automatic Torsion: Independent current loop control realizes real torsion control, can realize low frequency, large output torsion control under VF control mode, the torsion response time is less than 40ms. 5. Wide Voltage Input: Adopt wide voltage design, the input voltage range is 320‑460V, can be protected from the influence of voltage fluctuation, stable and reliable. 6. Multi Speed Operation: Simple PLC function, up to 16 stage speed operation and 4 stage acceleration can be realized through self defined control terminals. 7. Switch Freely: The 7 frequency sources of keyboard, analog voltage, analog current, multi speed running, PID control, remote communication and keyboard encoder can be switched in various ways. 8. Easy Operation: No need complicated parameter setting, the most suitable parameters can be automatically set according to the purpose of the motor, automatic detect load current, adjust output voltage, perform maximum efficiency control and operation.
