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

Q: What is frequency conversion? What is the function of frequency converter?: Theoretically, the inverter can be used in all mechanical equipment with electric motor, the motor starts, 5-6 times higher than the rated current, will not only affect the motor service life and consume more power. In the design of the system in the motor selection will leave some margin, the speed of the motor is fixed the same, but in actual use, sometimes running at low or high speed, so the frequency transformation is very necessary. Transducer can realize soft starting and compensating power factor of motor

Q: What's the function of this brake unit?: In order to digest this part of the energy, the transducer consumes the energy of the feedback current through the resistor.If the inverter is more advanced, this part of the current can also be sent to the call back network through the controlled rectifier bridge. There's no braking resistance.

Q: What are the parameters of the frequency converter? Thank you: That is to say, the upper and lower amplitudes of the output frequency of the inverter. Frequency * * is to prevent misoperation or external frequency set signal source failure, resulting in the output frequency is too high or too low, in order to prevent damage to a device protection function. In the application, according to the actual situation can be set. This function can also be used as a speed limit, if the conveyor belt, the conveying material is not too much, to reduce the mechanical and wear belts, be driven by inverter, and the inverter upper frequency settings for a particular frequency, so it can make the belt conveyor running on a fixed low speed work

Q: How do two inverters synchronize?: Higher requirements, you can use 2 of the method, the middle of which potentiometer into a dedicated proportional controller. More secure and reliable, and the proportion can be adjusted precisely in 0--200%

Q: What does "frequency" in household appliances mean?: The new inverter refrigerator not only the reduction of power consumption, realize mute, and the use of high-speed operation can achieve substantial rapid freezing; in the washing machine, used frequency variable speed control, improve washing performance, washing machine popular in addition to saving energy and silent, still ensure soft clothing washing and other aspects of the introduction of control new content;

Q: I would like to ask, the inverter in use in the grid is very high?: Now the domestic and foreign status of power grid is different from that of Europe and the United States Department of conversion products to the domestic needs change, in fact, if you choose, you can choose domestic brands inverter, after all, or your own brand more familiar with the situation! Our factory in Chongqing, is used in conjunction with Kang high voltage frequency conversion, suitable for input voltage range comparison, but also very suitable for domestic power grid conditions.

Q: How do you set the frequency with panels?. What are the specific steps?: The parameter 700 is the starting signal, the 1 is a panel key starting, and the 2 is an external signal starting;The parameter 1000 is the frequency setting value, and the 1 is a panel lifting key, and the frequency is changed, and 2 is changed by the external analog signal.Your problem, the start signal is set up, finished, the parameter 1000 should be 1, so that the panel set frequency, and then set the parameter 1031 to 1, so that it automatically save the frequency changes after the value

Q: Can a power converter be used in a motor with small power? Will it burn the motor?: Yes, the motor will not burn, if it is a small power converter, with large power motor, frequency converter will burn point

Q: How to choose frequency converter?: 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 is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on.
