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:What is the characteristic of the variable pole speed method?: Edit this paragraph speed method First, variable pole alignment speed method This kind of speed control method is to change the stator winding winding way to change the cage motor stator pole pairs to achieve speed control purposes, features are as follows: with hard mechanical properties, good stability; no slip loss, high efficiency; wiring Simple, easy to control, low price; stepless speed regulation, large level difference, can not get smooth speed control; can be used with voltage regulator, electromagnetic slip clutch with the use of high efficiency and smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on. Second, the frequency control method Frequency conversion is to change the frequency of the motor stator power supply, thereby changing the speed of its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Features: high efficiency, no additional loss during the speed control process; wide range of applications, can be used for cage type asynchronous motor; speed range, hard and high precision; technical complexity, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance. Frequency conversion speed is divided into the following basic frequency and frequency above the speed, the fundamental frequency is constant torque speed control mode, the frequency above the speed is constant power speed mode.

Q:What is the number of parameters of the motor frequency of the Siemens inverter?: Different types of Siemens frequency changer pole pair parameters different. 6SE70 is p109; The following is the p109 parameter description: P109 * Motor #PolePairs 109 For the synchronous / asynchronous motor input motor pole pairs of the function parameters. If the rated frequency (P107) and rated speed (P108) change, automatic calculation This parameter, if necessary, checks and verifies this parameter. note: - for some of the pulsed encoders (P130 = 11, 12, 15, 16) The maximum number of pole pairs of P109 = 15 can be achieved - P109 must be written when the write function (P060 = 6) is implemented. - Automatic calculation of the pole pair on the motor with regenerative feedback on the rated data Number to be added. Where the function map: 360.2, 361.2, 362.2, 363.2, 364.2 ? MM4 series is r313, which is calculated by the input rated frequency and rated speed calculated read-only value, must be selected in the p3900 to calculate the correct value. You can also set pole pairs by p314. ? S120; G110; G120; G130; G150; S150 with MM4 series.

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:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?: Such a high speed estimated motor can not reach, to increase the gearbox Specific algorithm: n = 60f / p P is the number of pole pairs, f is the frequency. The pole pair number of the 6 pole motor is 3. F = n * p / 60 = 8000 * 3/60 = 400 Hz.

Q:Variable frequency pump pressure in the very low flow instability, why?: From the performance curve, the flow becomes smaller, the combination of pressure and frequency adjustment flow will only stabilize the flow at a small value, the pressure will be reduced, because the work point will move down.

Q:A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole: The upper limit frequency transferred to 25HZ, the number of poles changed to 2, try to run when the motor speed test

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:Will the 75KW4 pole motor can be used to increase the speed of the inverter?: Can not, only slow down, on our national grid, 50HZ is the largest. At least with the inverter can not be achieved.

Q:What are the AC motor speed control methods? What are the characteristics of each: 1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency

Q:Three sets of batteries (540V) DC power supply U / f inverter.: It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
