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
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. Neither SINEE nor its distributors shall be responsible
or liable for misuse of the information contained herein or mismatching the inverter with the
motor.
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 the
content herein without notice.
