Product Description

Main Features:

1. SVC (Sensorless vector control):Torque control accuracy: 5% rated torque. Speed control accuracy: ±0.2% rated synchronous speed. 
2. VVF (Vector decoupling based VF control): The steady performanceis the same as that in SVC.
3. Wide speed regulation range, load capacity at low frequency: SVC/0.5Hz/150% rated load, VVF/1.0Hz/150% rated load.
4. Optimized current and voltage protection algorithm ensures that motor can accelerate/deceleratein 0.1S.
5. AVR function makes output voltage stable at grid voltage fluctuation.
6. Load disturbance compensation ensures failure-free operation of motor.
7. Auto-searching motor speed at restart smoothes thestart of motor without current over-shoot.
8. 2 acceleration/deceleration modes: linear and S curve.
9. The performance and stability are improved significantly with dual- CPU.
