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.

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.

1.2.3 Setting Modes of Inverter
The setting mode of inverter refers to that what kind of physical quantity inverter is taken as
control object when driving motor.
Speed setting mode is to take motor speed as the control object
Torque setting mode is to take motor torque as the control object.
Set through various and flexible methods such as numeric setting, analog voltage, and analog
current or other mathematical combinations. Jog speed setting mode is prior to other setting
modes, i.e. when pressing
JOG
＋／－
on keypad or turning control terminals FJOG and RJOG on, no
matter what the present setting mode is, the inverter will automatically switch to jog speed
setting, or the combination of jog speed+primary speed or jog speed+auxiliary speed setting .
See Figure 1-1 and Figure 1-2 for the details of all speed setting modes of EM303B.

2.3 Considerations of Installation Site
2.3.1 Installation Site
Considerations for installation site:
Good ventilation indoor
Ambient temperature: -10C～+40C
No high temperature and high moisture, humidity:＜90%RH, no water drops or any
other condensation
Never install on flammable materials
No direct sunlight
No flammable, corrosive gas or liquid
No dust, floating fiber or metal particles
Firm and steady installation base
No electromagnetic interference, and keep away from interference source.
2.3.2 Ambient Temperature
Install inverter in a place with good ventilation to improve the reliability of inverter operation.
When inverter is mounted inside a cabinet, cooling fan or air conditioner is a must. Keep the
ambient temperature below +40C.
2.3.3 Precautions
Please take protective measures during installation to prevent foreign matters like metal
particles or dust from entering the inverter when drilling. After installation, please take off
the protective devices.
2.4 Direction and Space of Installation
Cooling fan(s) installed inside EM303B is for forced air cooling. For good cooling
circulation, please mount inverter vertically, and leave sufficient space between the inverter
and wall or other objects. See Figure 2-2.

Remarks:
1. The values listed in the table refer to that the HDC and MAF required when single
EM303B is mounted in an enclosed place.
2. The HDC is calculated based on the rated voltage, rated current and preset carrier
frequency of each model.
3. 3. If more than one EM303B have to be installed in an enclosed place, please add HDC
and MAF.
