Q:Frequency converter, fault, contact action: The frequency converter has 1-2 relay outputs, that is, digital output. By default, most of the output of the fault is the relay. The general definition of the 2 relays is defined as a running output and a fault output.This contact output and inverter circuit inside the electrical isolation, can use 24V, you can use 220V, you can use any lower than the voltage level of 500V to use this contact, according to the actual needs of love then why.

Q:How can I learn the converter well?: If you are engaged in maintenance or after sale, you must know the main circuit diagram of the converter, rectifier, filter, inverter. Some electronic components must know, from the main circuit is frequently such as varistors, charging resistance, pressure resistance, no sense of capacitor, filter capacitor, driving circuit of multiple optocoupler such as 2503503120316, this is referred to as the optocoupler and the role, you must know the pin. Because the maintenance process should always be to determine the quality of the device.

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: Using PLC to analog converter control input frequency up to speed off from the requirements of the inverter frequency source set P-00 speed by 00 digital operation panel to analog frequency PLC given 0102 given frequency parameters can choose the set of 01 or 02 and the period of quick closing even P-17P-19 parameters affect analog control

Q:What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.

Q:What do you mean by the capacity of the inverter and the capacity of the motor?: That's not the case at all"Capacity" and "power" are essentially different. Usually we say that a large transformer capacity is how much KVA, but not to say how much KW, because the two are not the same thing

Q:What does the base frequency 60Hz represent in the inverter?: The schematic diagram of the basic frequency parameters of the converter is shown in figure.Below the fundamental frequency, the output voltage of the converter varies with the output frequency, and the V/F= constant is suitable for constant torque load characteristics.Above the fundamental frequency, the output voltage of the inverter maintains the same voltage rating of the power supply, which is suitable for constant power load characteristics.

Q:1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Or, ask another question: "under what circumstances can the frequency converter go to the cable of the frequency conversion motor without using shielded cable?" Is there a "no need to use shielded cable" basis?

Q:Knowledge, principle and operation method of frequency converter.: Summary of the working principle of frequency converter:Before the work principle of frequency converter is understood, it may be possible to see why the inverter is sacred first Inverter is the frequency power supply (50Hz or 60Hz) converted to various frequency AC power supply, in order to realize the motor speed change operation of 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 reverse into alternating current (and core control circuit: AC - DC - AC the process). And the frequency conversion technology should be born with the need of AC motor stepless speed regulation. The working principle of formula to express the words is: n = 60 f (1 s) /p (1) - N - speed asynchronous motor; F -- asynchronous motor frequency; s - motor slip; P - pole motor. By formula (1), the speed n is proportional to the frequency f. As long as the frequency of F can be changed, the speed of the motor can be changed. When the frequency f changes within the range of 0 to 50Hz, the speed range of the motor is very wide. Frequency converter is to change the frequency of motor power to achieve speed regulation, is an ideal high efficiency, high performance speed control means.

Q:What is the function of a frequency converter on an electric motor?: Frequency converter integrates high voltage, high power transistor technology and electronic control technology, and has been widely used. The role of frequency converter is to change the frequency and amplitude of AC motor power supply, thus changing the period of its moving magnetic field, to achieve the purpose of smooth control of motor speed. The inverter speed control, makes the complex simple, most of the original work can only be done by a DC motor instead of frequency converter + AC squirrel cage induction motor, reduce the volume, reduce the maintenance rate, to a new stage of development of the transmission technology

Q:What is the difference between a frequency converter and a servo controller?: Frequency conversion technology: simple frequency converter can only adjust the speed of AC motor. At this time, it can be opened or closed loop. It depends on the control mode and frequency converter. This is the traditional V/F control mode. Now many of the inverter has been through the establishment of a mathematical model of AC motor, the stator magnetic field UVW3 phase into two current can control the motor speed and torque components of the inverter can now most famous brand of torque control are used in such a way to control the torque of each phase, UVW output current detection device Jiamoer the effect of sampling current feedback constitute a closed-loop negative feedback loop PID regulator; it can not only control the speed of the motor can also control the motor torque and speed control accuracy is better than v/f control, encoder feedback can also be added or not, and when the control precision and the response is much better.
