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.

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 of AC 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.

User Manual EM303B General Purpose Inverter

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

3.2.5 Wiring Main Circuit on Input Side Installing a Circuit Breaker

Always install an air circuit breaker (MCCB) between the power supply and input terminals.

 Choose a MCCB with a capacity of 1.5-2 times of the inverter’s rated current.  The time characteristics of MCCB should meet that of inverter’s overheating protection

(150% of rated current /1 minute).

 If single MCCB is shared by two or more inverters or other devices, the contact of fault

output relay shall be connected to power contactor coil, so that the power supply will be turned off by the fault signals, as shown in Figure 3-5.

MCCB

EM303B

Figure 3-5 Connecting to Input Circuit Breaker

Installing a Leakage Circuit Breaker

High frequency leakage current is generated by high frequency PWM signal output of inverter. Select a special purpose leakage breaker with a trigger current≥30mA. For a regular leakage breaker, the trigger current≥200mA and the active time at 0.1S or above.

Installing an Electromagnetic Contactor

Install an electromagnetic contactor which is applicable to inverter as shown in Figure 3-5.

User Manual EM303B General Purpose Inverter

 Start/stop of the inverter can be controlled by the electromagnetic contactor on input side.

Inverter may break down if the electromagnetic contactor is on and off frequently. The operation interval between start and stop of the inverter shall ≥ 30 minutes.

 The inverter will not automatically start after power failure.

Connecting to the Terminal Block

Power input phase sequence is not related to the phase sequence of terminals R, S, and T on the terminal block, any two of them can be connected randomly.

Installing an AC Reactor

If the inverter is connected to a transformer with big-capacity (≥600kVA), or power supply is connected to capacitive load, an excessive big surge current will occur and rectifier of inverter can be broken down. Install an optional 3-phase AC reactor on input side of inverter to suppress peak current and voltage, and improve power factor of the system.

Installing a Surge Absorber

Install a surge absorber for inductive loads (electromagnetic contactors, solenoid valves, solenoid coils, or electromagnetic circuit breakers) nearby the inverter.

Installing a Noise Filter on Power Supply Side

To filter noise transmitted between power cable and the inverter, andthe harmonic distortionof power grid caused by the noise produced by the inverter.

 A special purpose noise filter is required for the inverter.  Correct vs incorrect installations of noise filters as shown in Figure 3-6 and Figure 3-7.

3.2.6 Wiring the Output Side of Main Circuit Connecting the Inverter to Motor

 Connect inverter output terminals U, V, and W to motor input terminals U, V and W.  Confirm that the motor forwards with the Forward Command. Switch any 2 of the

inverter output terminals U, V, or W to each other and reconnect if the motor reverses.

Never Connecting Power Supply Cable to Output Terminals Never connect power supply cable to output terminals. If the output terminalsare connected to power supply, the inverter would be damaged.

Never Short-Circuiting or Grounding Output Terminals

Never touch output terminals directly with bare hands, or connect the output cable to the housing of inverter. Otherwise, an electric shock and short-circuit may occur. Furthermore, do not short-circuit the output cable.

Never Using a Phase-shifting Capacitor

Never connect phase-shifting electrolytic capacitor or LC/RC filter to the output circuit. Otherwise, inverter will be damaged.

Never Using an Electromagnetic Switch

 Never connect electromagnetic switch or electromagnetic contactor to the output circuit.

Otherwise, failure to comply will cause overcurrent or overvoltage protection. Even worse, inverter will be damaged.

 Please make sure that the inverter stops before installing electromagnetic contactor to

switch grid power supply.

Installing a Noise Filter on the Output Side

Install a noise filter on the output side of inverter to reduce inductive interference and radio interference.  Inductive interference: Electromagnetic induction generates noise on the signal line

which may cause the control device malfunction.

 Radio interference: The high frequency electromagnetic waves generated by inverter and

cable cause radio devices nearby to make noise when receiving signals.

Countermeasures Against Inductive Interference

As stated previously, except installing a noise filter, all output cables can be routed through a grounded metal pipe to prevent inductive interference on the output side. The distance between output cables and signal line should＞30cm, and the inductive interference will be reduced considerably, as shown in Figure 3-9.

Cable Length Between Inverter and Motor

The longer cable between the inverter and motor is, the higher carrier frequency is, and the greater high-frequency harmonic leakage current on its cable is. All of which will affect inverter and its peripherals. See Table 3-2 to adjust carrier frequency for reducing the high-frequency harmonic leakage current. When motor cable＞50m, please connect a special 3-phase AC reactor of the same capacity as that of the inverter to the output terminals.

Remarks:

1. Take the voltagedrop into consideration for selecting cable. Generally the voltagedrop

should be＜5V and calculated according to following formula:

Voltagedrop=√3* Cable resistance ratio (Ω/KM)*Cable length (m)*Rated current (A)*10

-3

2. If placed in plastic duct, the cable should be uprated by one level.

3. The cable should be connected to the applicable cable and wiring terminal.

4. The size of grounding cable should be the same as that of power cable when the size of

power cable is less than 16mm2. However, when the size of power cable>16mm2, the size of grounding cable should not be less than half of it, but at least16mm2.
