Q: A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?: A) PE inverter main circuit terminals (E, G) must be grounded, the motor can be grounded and the inverter with the common ground, but not with other equipment, must play ground pile, and the ground should take place far away from electrical equipment. At the same time, the cross-sectional area of the grounding wire of the converter shall be no less than 4mm2, and the length shall be within 20m.(b) in the ground wire of other electromechanical equipment, the protective earthing and the work earthing shall be separately provided with grounding electrodes, and finally shall be imported to the electrical position of the distribution cabinet. The shield of the control signal and the shielding of the main circuit wire shall also be separately provided with earth electrodes, and finally shall be incorporated into the electrical junction of the distribution cabinet.

Q: How does the frequency converter change the voltage and change the speed of the motor?: The inverter does not change the voltage to adjust the speed of the motor. Under the premise of constant voltage, the frequency of the alternating current is changed to adjust the speed of the motor. Typically, at the frequency of 50Hz, the synchronous speed of the quadrupole motor is 1500 rpm, and if the frequency is increased to 60Hz, the synchronous speed should be 1800 rpm; if it falls to 40Hz, the synchronous speed should be 1200 rpm. In the limited frequency range, the power is constant, the higher the speed, the smaller the torque, the lower the speed, the greater the torque. Formula for speed calculation (Rev / min):60 seconds * / log polar frequency. The middle pole of a pair is 2 poles of 1 pairs, i.e., the quadrupole motor is 2 pairs of magnetic poles.The frequency of the converter is stepless, continuous and adjustable, so the speed of the motor is continuously adjustable in a certain range.

Q: What is the main function of the frequency converter on the machine tools?: Where is the difference between soft starter and converter?

Q: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: When we design the frequency converter to drag the motor load (mostly fan and water pump general machine), we should use shielded cable. We refer to the GB/T21209-2007 "inverter power supply design and performance of cage induction motors in section 9.1.4" guide "motor power cable" 9.1.4.1 "recommended configuration" in the "provisions of more than 30kW motor wiring should adopt the single core power cable or a plurality of grounding wire arranged symmetrical cable. Small power and suitable for wiring, priority is to use multi-core shielded cable." As the PE line symmetrical configuration of the 3+3 inverter dedicated cable, construction is always raised, not wiring, we later too lazy to explain, usually directly with the 3+1 type multi-core shielded cable. From the running situation, the effect is also good.

Q: There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: Two inverters with the same frequency and start signal, so that it can be synchronized; another way is to do in front of a given frequency inverter with potentiometer, given analog output signal of the first station to do second machines, it can be done simultaneously; but you have to say clearly what is what specific brand series in order to further clear the inverter parameters, otherwise only vague answers.

Q: How do you understand the ramp up (descent) time of the inverter? Thank you!: The ramp up time is to start from the 0 speed, inverter, running to reach the given speed (for example: 1420) the time required, in general, the longer the time, the frequency converter and motor impact is small. In the actual work process, according to process requirements to set the length of time. (more than 10-15 seconds) or so, if it is a pump or fan motor, do not need to change its rise time, the default can.

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 do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?: The main function of the transformer is to change the voltage, and to solve the problem of voltage magnitude (amplitude, RMS)The main function of frequency converter is to change frequency and solve the problem of voltage and frequency.The main application of frequency converter to motor is to adjust the speed of motor by adjusting frequency. Because the speed of the motor is related to the frequency of the power supply. Can play a role in energy saving.

Q: What's the role of an electric car, the part of a traditional car?: The main advantage of inverter products in electric vehicles lies in:1, reliability: three heavy over-current protection, three heavy voltage protection, three heavy drive protection, ensure the motor controller reliable and stable operation.2, the control strategy is superior: the motor controller adopts vector control technology, which has the advantages of superior performance and high reliability. It is suitable for AC asynchronous or permanent magnet synchronous motors;3, the large capacity output capability: the output end of the motor with no gearbox or reducer, greatly reduces the noise, fault point and mechanical drive system control mode is simple, cost saving, high reliability, good stability of vehicle operation;4, the power performance is good: acceleration performance (0 ~ 15 seconds 50km/h), more good economic performance (0.9 degrees /km @40km/h);5, fault diagnosis and treatment: in order to improve the reliability of the whole vehicle, motor control system must have the function of fault diagnosis, and can save the trouble, convenient after analysis, also through the diagnostic ports can be implemented online debugging motor controller and recording various operating curve facilitates optimization of the whole control system;6, efficient braking energy recovery: give full play to the advantages of pure electric vehicle powertrain system, improve energy utilization, motor control system must have the brake energy recovery function.7, simple: motor controller quality is reliable, and light weight, easy to layout, wiring, maintenance convenience and so on, the industrialization prospect is very good.

Q: What are the benefits of installing economizer in industrial enterprises?: Frequency converter is a device that regulates the speed of an electric motor by adjusting the output frequency:1. The frequency converter can only reduce the motor speed by reducing the power supply frequency. The application environment is limited and the automatic control function is not available. It can not be used in many load changing occasions;Have a lot of 2 odd harmonics, frequency converter operation, it will seriously affect other equipment life and efficiency, at the same time use but also affect other precision control of the equipment in the factory, such as computer, automatic control system, monitoring system and so on;3 、 frequency converter serial access to the customer's low-voltage power system, the power supply of the customer security risks.
