Now the Shanghai Volkswagen Schneider, L.D., and many domestic large enterprises supporting inverter and electronic components products supply, for many years by the number of units as the best supplier.

Q:What is called vector converter?: Vectors and vectors are mathematical methods of vector (vector) analysis, both of which are of the same concept

Q:That is, some parameters of the inverter, such as torque, current, frequency, etc., are displayed on the Kingview software interface, but not through the PLC. The idea that the MODBUS protocol between SIEMENS and 200PLC has never been successful before, so that's the idea of the ABB. If it can be achieved,Is it necessary to write the script program on the Kingview, and what problems should I pay attention to when using the MODBUS protocol in Kingview software?The problem is a little bit more, I hope the experts teach me this rookie! Thank you: As long as there are 485 communications can be, the frequency converter manual on the MODBUS protocol, the address of each parameter, in the king view on the link can do, and I hope to adopt.

Q:What is the main function of the frequency converter on the machine tools?: According to the working characteristics of machine tool spindle drive structure, most of the early machine adopts three-phase asynchronous motor with multi-stage gearbox, with the continuous development of technology, machine tool has been greatly improved, so as to put forward new requirements on the spindle system, and because use varies in CNC machine tools, CNC lathe, CNC drilling accounted for 42%. Boring and milling machine CNC grinding machine, punching machine accounted for 33%, accounting for 23%, accounting for 2% of the other, in order to meet the needs of the former two types of CNC machine tools a wide range of large, proposed the following requirements of the spindle drive: main drive motor power range should be 2.2KW~250KW; to have a wide range of stepless speed regulation, such as constant torque speed and 1:10 constant power speed in the range of 1:100~1000; the main transmission requirements are capable of driving the four quadrant; in order to meet the requirements of thread turning, spindle can realize synchronization control and feed.

Q:I would like to ask, the inverter in use in the grid is very high?: Yes, because the harmonic generated by converter works has certain influence on the quality of power grid, so the demand for power grid is higher. Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter adjusts the voltage and frequency of the output power by the breaking of the internal IGBT. According to the actual needs of the motor, it provides the required power supply voltage, and then achieves the purpose of energy saving and speed regulation,

Q:First of all, I would like to achieve the frequency converter with motor static linear acceleration, high-speed linear deceleration stop processFirst question: I say kind of situation, three paragraph speed start, 0.1hz---> high 30hz-->0.1hzSecond problem: manual speed instruction 1, speed 2, speed 3 instruction instruction I want to use PLC to control three speed motor with three reverse contact dry. I understand speed instruction 1 is switched on (2, 3 connected) transmission section set the frequency with the frequency segment set 0HZ123 AssociationThird questions: manual section, speed command, main frequency and STEP1-STEP7 stage setting frequency, I use PLC analog to the frequency main frequency setting, plus and deceleration, STEP1-7 are set 0, can achieve what I wantInitial contact frequency converter, home pointing: Control the three section speed inversion section, the speed instruction setting surface needs three frequency (M series frequency converter P-17, P-18, P-19) beforehand, which frequency conduction section fast contact line is needed

Q:The functions of frequency converter and UPS are similar, especially the power frequency UPS?: The inverter is actually an inverter. It is the first AC into DC. And then use the electronic element to switch DC power into AC inverter. In general. Large power SCR. And an adjustable frequency. The device can be adjusted in a certain range of frequency is used to control the motor speed. The speed can be adjusted. In a certain range. The inverter is widely used in AC motor speedThe UPS power supply is also called an uninterruptible power supply. An inverter with an adjustable frequency. Battery powered. For short time power supply of computer and other equipment in case of power failure. Prevents sudden power loss and file loss.

Q:What's the use of switching frequency of converter?: The chopper device also has switching life, the higher the switching frequency, the shorter the life of the inverter, and will reduce the inverter output current and power. The smaller the chopping frequency, the higher harmonic content and the more serious harmonic pollution.

Q:What is a frequency converter?: Inverter is the power frequency (50Hz or 60Hz) transform into a variety of frequency AC power, to realize the motor speed operation of the equipment, the control circuit controls the main circuit of the rectifier circuit will be converted into AC DC, DC intermediate circuit of the rectifier output smoothing filter, inverter circuit to DC and then inverse into AC. For inverters such as vector control inverters that require a great deal of computation, sometimes a CPU for torque calculation and some corresponding circuits are needed. Variable frequency speed regulation is achieved by changing the frequency of motor stator winding power supply.

Q:Where is the difference between soft starter and converter?: The soft starter changes the supply voltage only and is equivalent to a step-down starter. The frequency converter is much more complex and much more expensive than the soft starter. The inverter also has a soft start function, which is achieved by changing the power frequency. Difference between high voltage starter and low voltage starterThe main circuit of the soft starter is thyristor, and the start-up process is completed by gradually changing the turn-on angle of the thyristor. This is the basic principle of the soft starter. In the low-voltage soft starter market, a wide range of products, but high voltage soft starter products are still relatively small. High voltage soft starter is the same as low voltage soft starter, but there are some particularities in high voltage soft starter and low voltage soft starter:
