Preface

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

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.

EM303B General Purpose Inverter

1.2 Definition of EM303B Operation Status

1.2.1 Operation Status of Inverter

Parameters setting status

After power is on, inverter finishes initialization and enters standby status without fault

or start-up command. Meanwhile, it does not output.

Normal running status

After receiving active start command through keypad, control terminal or RS485, the

inverter drives motor in accordance with the requirements of setting input.

JOG running status

Set by keypad, external terminal or RS485 to make motor run as per JOG input speed.

JOG stop status

Refer to the process that the output frequency drops to zero in JOG deceleration time

after JOG running command is not active.

Autotuning status

Set by keypad to autotune motor’s parameters in stationary or rotational autotuning.

Stop status

Refer to the process that the output frequency drops to zero in given deceleration time

after running command is not active.

Fault status

Status of inverter at protections, all kinds of faults and failures.

1.2.2 Control Modes of Inverter

The control modes of inverter refer to that the inverter controls motor rotation as per required

speed and torque with open loop or close-loop control mode. The control modes include:

General open loop space vector control——V/F control

Applicable to the applications of low speed changes and low speed stability accuracy

demand, and meet needs of most ofAC motor drives.

SVC 0—— Open-loop vector control without PG feedback

Only estimate speed in real-time, but no feedback control. Output current is under

real-time close-loop control, output of motor reaches 150% of rated torque at 0.5Hz, and

inverter automatically traces load variables and limit output current to make it not exceed

the maximum value. Even if there is sudden load change, quick acceleration or

deceleration, inverter will not trip overcurrent, short-circuit, and etc., and keep high

performance and reliability.

SVC1—— Torque control(Close-loop vector control without PG feedback)

Not only estimate speed in real-time, but also conduct feedback control. Speed and

current are under real-time close-loop control. Not only speed control but also torque

control can be realized. A regular AC induction motor can perform as an AC variable

speed motor and an AC torque motor by adopting this control mode. It is a genuine

sensorless vector control.
