Product Description:

Introduction of SVF-G7 Series High-performance Vector General-purpose Frequency Inverter

  

1. Voltage class: 380V

 

2. Range of power: 0.4KW~450KW

 

3. Stable and reliable Control Mode

 

(1) VF control: Multiple curve could been chosen, Linear V/F curve, 2.0 times power drop torque V/F curve, custom V/F percentage(can realize manual energy saving control), multipoint VF curve. This apply to the situation that one frequency inverter drives multiple motors, such as fan, water pump, engraving machine, injection molding machine etc.

 

(2) Open-loop vector control: Steady speed with high precision, wide range of speed governing, as the speed ratio is 1:200 and 180% rated torque could be output in 0.5Hz. Good dynamic performance.

 

Open-loop vector is suitable for high-Performance universal occasions such as machine tools, centrifuges, cranes and handling equipment, rolling mill and other loads.

 

(3) Torque control: Fast torque response,<20ms, precision torque: <5%, applied to winding, drawing and other occasions.

Q:Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
7 seconds more than a change, too often. It is estimated that the inverter will not work. Suggest:
Q:The Schneider inverter reports the nlp command
1, the inverter control circuit with an external 24V power supply, the main circuit did not power 2, PO and PA between the short film can not cause this failure.
Q:What is the difference between AC and DC frequency converters?
Advantages and disadvantages: Advantages: inverter air conditioner with variable frequency power supply, inverter compressor, electronic expansion valve and microcomputer technology, the organic combination of air conditioning to further improve the performance, the use of room temperature fluctuations, better comfort, the better Power supply voltage fluctuation is not sensitive, the compressor starts, the general non-stop, cooling capacity in the range of 35% to 117% change, to avoid the frequent open air-conditioning, to extend the life of the compressor, while efficient, Features. Disadvantages: the price is more expensive, compared with ordinary air conditioning, about 1/3 to 1/4 of the price, at the same time, because the inverter air conditioner control system and frequency conversion system is more complex, higher requirements for components, compared to ordinary air conditioning , Inverter air conditioner failure rate is high, and, due to the use of frequency conversion technology, at the same time, will produce harmonic pollution. What is DC inverter air conditioner? DC inverter air conditioner is relative to the AC inverter air conditioner, in fact, its name is not correct, because the DC and no frequency, it is by changing the DC voltage to adjust the compressor speed, thus changing the air conditioning cooling capacity, It can only be said to be a DC variable speed air conditioning, not strictly in the sense of inverter air conditioner.
Q:How many types of CVT are classified?
classification: To achieve stepless speed change, according to the transmission can be used liquid drive, power transmission and mechanical transmission in three ways. Liquid drive Liquid drive is divided into two categories: one is hydraulic, mainly by the pump and the motor or composed of valves and pumps composed of variable speed transmission, suitable for small and medium power transmission. The other for the hydraulic, the use of hydraulic coupler or hydraulic torque transmission, suitable for high power (hundreds to thousands of kilowatts). The main features of the liquid drive are: speed range, can absorb the impact and prevent overload, transmission efficiency is high, long life, easy to automate: manufacturing precision requirements, the price is more expensive, the output characteristics of constant torque, Large, easy to run when the oil spill.
Q:What is the characteristic of the variable pole speed method?
Seven, hydraulic coupler speed control method The hydraulic coupler is a hydraulic drive, generally composed of a pump wheel and a turbine, which collectively referred to as a working wheel and placed in a sealed housing. The shell is filled with a certain amount of working fluid, when the pump wheel in the prime mover driven under the rotation, in which the liquid by the blade to promote the rotation, under the action of centrifugal force along the outer ring into the turbine wheel, in the same direction to the Turbine blades are thrusted to drive the production machinery. The power transfer capacity of the hydraulic coupler is consistent with the size of the relative filling fluid in the shell. In the course of work, change the liquid filling rate can change the coupler's turbine speed, made stepless speed regulation, which is characterized by: power to adapt to a large range, from several tens of kilowatts to thousands of kilowatts to meet the different power needs; Simple, reliable, easy to use and maintenance, and low cost; small size, can accommodate large; easy to control and easy to achieve automatic control. This method is suitable for fan, pump speed.
Q:What parts of the inverter composition
The main converter are: rectifier module, inverter module, capacitor, driver board, motherboard, shell composed of these parts!
Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
If the Delta C2000_M is the Modbus drive can not handle Not to the official website under the manual
Q:11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
Frequency converter in the 5-50Hz is constant torque frequency, 50-100Hz is constant power frequency, to see what you want to get the effect
Q:Delta VFD-F frequency converter how to adjust the number of poles
Go to the official website of some inside a detailed description
Q:There is no inverter comes with simple PLC programming function
The PLC is programmed to handle digital and analog, the core of the entire control system. It can output the digital to the inverter, so that the inverter is reversing, you can output the analog to the inverter set speed, but also through the communication, direct control inverter
