Q: What is the difference between a frequency converter and a servo controller?: Servo system: 1 servo drives in the premise of the development of frequency conversion technology, the current loop in the internal drive, speed loop and position loop (inverter without the ring) of algorithm operation and control technology is more accurate than the general frequency, but also in the function than the traditional servo many powerful, the main point can accurate position control. To control the speed and position of the pulse sequence controller sends the (of course there are also some integrated servo control unit or by bus communication way directly to set the parameters of position and velocity in the drive), drive the internal algorithm and faster and more accurate calculation and better performance of electronic devices to be more superior to converter. 2, motor servo motor of the material, structure and machining process is much higher than that of the AC motor drive inverter (general AC motor or constant torque, constant power and other types of motor), that is to say when the power driver output current and voltage and frequency change quickly, the servo motor can generate action response according to the change power changes, response and anti overload capacity is much higher than that of AC motor inverter drive motor, fundamental serious differences is two different performance. That is to say, not the inverter can not change the power supply signal, but the motor itself can not respond, so in the frequency of the internal algorithm settings, in order to protect the motor to do the corresponding overload settings. Of course, even if the output power of the inverter is not limited, some high-performance inverters can directly drive the servo motor!

Q: What's the use of switching frequency of converter?: By adjusting the switching frequency, system noise can be minimized, waveform smoothing is the best, and interference is minimal. Because the frequency converter mostly adopts the form of PWM modulation to carry out the frequency converter. That is, the output voltage of the inverter is actually a series of pulses, and the pulse widths and intervals are not equal. The size depends on the intersection point of modulation wave and carrier, that is, the switching frequency. The higher the switching frequency, the more the number of pulses in a cycle, the better the smoothness of the current waveform, but the interference to other devices is also greater. The lower the carrier frequency or the bad set, the motor will make unpleasant noise.

Q: Why does the frequency converter cause interference?: Reasonable wiring: the concrete method has:The power line and signal line of the equipment shall be as far as possible from the input and output lines of the converter.Other equipment power lines and signal lines should be avoided parallel with the input and output lines of the inverter.If the above measures are not successful, then continue the following measures:

Q: How does frequency converter realize variable frequency speed regulation?: The frequency of the electric field is changed, and the frequency of the original fixed 50 Hz is reduced as required, and then the rotation frequency of the induction motor is changed

Q: What is called vector converter?: The vector converter technology is based on the DQ axis theory. Its basic idea is to decompose the current of the motor into D axis current and Q axis current, among which DVector converter

Q: Why does harmonic generator produce harmonic? What's his working principle?: Harmonic generation mechanism of inverter inputThe main circuit of inverter is composed of AC-DC-AC, external input 380V/50Hz power supply through the three-phase bridge rectifier, a DC voltage, AC voltage by the capacitor filter and high power transistor switching element for variable frequency inverter. In the rectifying circuit, the input current waveform is a rectangular wave irregular waveform, according to Fu Liye series is decomposed into fundamental and harmonics, the harmonic frequency is usually 6N + 1 harmonic, the harmonic interference input power supply system. If the reactance of the supply side is sufficiently small and the commutation overlap angle can be neglected, then the n order harmonic is the 1/n of the fundamental current.

Q: Can 220V use frequency converter to drive three-phase motor with 380V?: If it is a small power motor can be connected into angular motor then a three-phase inverter output 220 single-phase input 220 will be able to connect, as mentioned above can boost its output voltage frequency is equal to the maximum input voltage, so the 380 can not directly connected with the motor, but if you meet the above conditions can be considered,

Q: What does "frequency" in household appliances mean?: The air conditioner in Japan is gradually changed from pure PWM control to PWM ten PAM mixed control mode. The speed is controlled by PWM, U / F to maintain; when the speed exceeds a certain value, the system will adjust the fixed at the maximum value near, by changing the DC chopper on duty LL, improve the inverter input DC voltage, so as to keep the inverter output voltage and speed is proportional to the area, said PAM area

Q: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: 1. motor speed control will not be accurate2. the working current of the motor may become larger, and the motor will be burnt out3., excitation what will change, but also may cause the motor heating, burnout, will also reduce the efficiency of the motor;4. may also burn the inverter.5. motor output may be affected.

Q: Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: The difference between the display value and the measured value shows that the bus detection circuit is abnormal if the deviation is larger. Conversely, if the two value deviation is minimal or equal, the missing phase signal is abnormal. At present, there are two kinds of bus detection circuit used in our company: resistance voltage divider and operation comparison amplification (TL082). Corresponding to the detection circuit output 0 - 3.3V corresponds to the actual bus 0 - 1000V, the two circuits are relatively simple, maintenance only need to test the key point voltage in the circuit, you can easily find the fault point.
