User Manual EM303B General Purpose Inverter Thank you for purchasing EM303B series inverter. Document No.: 31010032 Version No.:104 Issue Date: 11/2015 EM303B is a general purpose vector control inverter. An induction motor with the help of EM303B canpossess fast speed response and torque control ability as a DC motor which makes the motion control system stable, precise,and quick. Main Features: 1. SVC (Sensorless vector control):Torque control accuracy: 5% rated torque. Speed Preface 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. It is the duty of any user to perform the appropriate, correct installation or configuration of the optional parameters of the devices.
