User ManualEM303B General Purpose InverterPrefaceThank you for purchasing EM303B series inverter.Document No.:31010032Version No.:104Issue Date:11/2015EM303B is a general purpose vector control inverter.An induction motor with the help ofEM303B canpossess fast speed response and torque control ability as a DC motor whichmakes the motion control system stable,precise,and quick.Main Features:1.SVC (Sensorless vector control):Torque control accuracy:5%rated torque.Speedcontrol accuracy:+0.2%rated synchronous speed.2.VVF (Vector decoupling based VF control):The steady performanceis the same as thatin SVC.3.Wide speed regulation range,load capacity at low frequency:SVC/0.5Hz/150%ratedload,VVF/1.0Hz/150%rated load.4.Optimized current and voltage protection algorithm ensures that motor canaccelerate/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 currentover-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 ofthe optional parameters of the devices.Neither SINEE nor its distributors shall be responsibleor liable for misuse of the information contained herein or mismatching the inverter with themotor.In the interests of commitment to a policy of continuous development and improvement,SINEE reserves the right to update the specification of the product or its performance,or thecontent herein without notice.More updates and information are available at www.sineedrive.com1
