About the product:

 

VFD-V Series Sensorless Vector Control Inverter uses the DSP control system to provide sensorless vector control, which has significant advantags 

compared with V/F control. 

Which is best serves OEM clients at the middle and high end of the market and 

support fans and pumps with specific requirements. The inverter’s flexible

design has sensorless vector control (SVC) and V/F control installed in one 

unit. It is widely used in applications that require high-speed control accuracy, 

rapid torque response, and high performance at low frequencies.  

 

Technical features:

 

1. Three control modes: Sensorless vector control (SVC), V/F control, torque 

Control. 

2. Overload: 150% rated current 60s; 180% rated current 10s.

3. Start-up torque: Sensorless vector control 0.5Hz/150% (SVC).

4. Built-in breaking unit: Brake resistance can be directly connected when rapid stops are required

5. Eight-step speed control, PID control, and traverse control.

6. Offering four multi-functional digital inputs, two analog inputs, one relay 

output, one analog output, and one open-collector output.

7. Automatic voltage regulation: When grid voltage is variable, this function 

automatically maintains a stable voltage output.

8. Offering RS485 serial communication interface and a standard Modbus 

communication agreement.

9. Optional LED external keypad for convenient and quick operation.

 

 

Input and output characteristic:

 

1. Input voltage range: 380/220V±15%

2. input frequency range: 47~63Hz

3. output voltage range:0~rated input voltage

4. output frequency range: 0~600Hz

 

Peripheral interface features: 

 

1. programmable digit input :4 input

2. programmable analog input:VI:  0~10V input,CI: 0~10V or 0~20mA input

3. Open collector output : 1 output

4. relay output : 1 output 

5. Analog output : 1 output , Respectively optional 0/4~20mA or 0~10V

 

Applications:

 

* Plastics and chemical fiber extrusion equipment 

 

* Metalworking machinery: Lathe,Milling machine ,planer ,Grinder

 

* Building materials : Cement glass main transmission equipment

 

* Rubber Machinery

 

* Wire and cable extrusion equipment

Soft starter are a far better alternative to star/delta and auto transformer starters.
The star/delta starter reduces start current but introduces a damaging torque transient when switching from star to delta connection. Furthermore star/delta starting does not always selection of the best start current level.
This sometimes means the load cannot accelerate to full speed in star configuration thereby making the star/delta
starter totally in effective.

A star/delta starter does not impact the way the motor stops, thus leaving the voltage ramp down with no control. The auto transformer reduces start current but also allows some control over the level of start current. Auto transformer starters does not eliminate the risk of a jump in torque when shifting voltage.

Pump 

1. Reduce hydraulic shocks in pipelines during start and stop.
2. Minimize mechanical stress on motor shaft.
3. Reduce starting current .
4. Under-current protection preventing damage from blocked pipe or low water situations.
5. Automatic reset functionality ensures continued operation of unmanned pump stations.
6. Phase rotation protection prevents damage from reverse pump rotation.
7. Instantaneous overload protection prevents damage from debris drawn into the pump.

Fans

1. Smooth application of torque preventing mechanical stress.
2. Reduced starting times over star/delta starting.

Power Supply: City power, Electricity Generator, three phase AC 380V or 660V ±15%, 50Hz, Battery capacity should comply soft starter boot require.

Suitable For : Three phase squirrel cage induction motor, rated frequency should be match with soft starter
Starting Frequency: No Specific Requirement

Cooling : Natural air cooling
Protect Level : IP 20
Environment : Altitude of 3000 meters below;
Ambient temperature: -25~+40℃;
Relative humidity : <90%;
Non-condensing, non-flammable, corrosive gases;
Non-conductive dust, good ventilation, low-vibration.

5 Mode of Start


Ramp voltage start :Require a smooth start occasion, output voltage as Page 1.
Current limit start : Have strict limitation of starting current, motor current curve as Page 2.
Snap action + Ramp voltage start : For heavy load, static friction force too big cause motor not running, starting curve as Page 3.
Snap action + Current limit start : For heavy load, static friction force too big cause motor not running, starting curve as Page 4
Heavy load strong shock start : For difficulty of heavy load motor start

5 Level Production Setting:


For different occasions, JJR2 production divide into five level, 0=Elementary ; 1: light load ; 2 : Standard 3 : Heavy load 4 : Advanced, Set by F12 Elementary forbid connect Instantaneous stop function, only have over-heat,
short circuit and default phase protection, suitable for Unconditional emergency start, like fir pump.
Light-load / Standard / Heavy-load has most of protection function, only difference is motor over load heat protection time curve as Page 1 & 5Advance as starting protection is more strict, parameters is like Heavy-load
