Q:How does frequency converter realize variable frequency speed regulation?: V=60f/nvMotor speed fFrequency nMotor poles without frequency converter to change the motor speed, only by changing the pole of the motor to achieve, frequency is 50HZ; through the inverter to change the motor speed is running frequency, no need to replace the motor can realize the speed control. The principle of speed regulation is the formula above.

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 start with frequency conversion. The frequency converter is controlled by a potentiometer, and the analog output signal (AO.GND) is sent into the converter and connected to the AI.GND port of the converter. If the pulse port can also be connected to the pulse port.

Q:Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: Mainly below the basic frequency of speed regulation,If higher than the basic frequency, that is constant power speed, that is, the higher the motor speed, the smaller the torque

Q:Can a power converter be used in a motor with small power? Will it burn the motor?: Yes, but you have to set some parameters that correspond to changes in the motor to play a protective role

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:What does Ro1c mean on a converter?: RO1C is the common terminal and the RO1A is normally closed, and the RO1B is normally open. The set of contacts is the output signal that is ready to run. That is, the self-test of the converter is completed and the output signal of the relay can be operated.

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: 1, requires two communications. The PLC and the Kingview use a communication port individually, and the PLC and the inverter use a communication port alone. 2, Kingview and PLC communication time, Kingview is the master station, PLC is from the station; and PLC and converter communication, PLC is the master station, frequency converter is from the station. 3, frequency converter control, do not use communication, use digital point output and analog output. 4, PLC and inverter as the slave station using Kingview configuration; Wang put the data to the PLC, let PLC run the program, go to the PLC of the configuration parameters of the inverter control read out, and then sent directly from the Kingview converter.

Q:What is the working principle of a three phase AC asynchronous motor inverter?: I. operating temperature. The internal electronic components of high power, extremely easy to be influenced by the working temperature of the product, the general requirements for 0 ~ 55 degrees, but in order to ensure the safe and reliable work, use should be considered under the best control in 40 DEG C. In the control box, the inverter shall be installed on the upper part of the box, and strictly comply with the installation requirements in the product specification. Absolutely no heating element or easy heating element shall be installed on the bottom of the converter.

Q:What is a frequency converter?: VVVF: change voltage, change frequency CVCF: constant voltage, constant frequency. AC power supplies used in various countries, whether for homes or factories, have voltages and frequencies of 400V/50Hz or 200V/60Hz (50Hz), and so on. Normally, a device that changes the alternating current of voltage and frequency to a voltage or frequency variable alternating current is called a frequency converter". To produce a variable voltage and frequency, the device first transforms the alternating current of the power source into direct current (DC).

Q:Where is the frequency converter used?: The machinery manufacturing industry, including: elevator, automobile, textile, printing and packaging, paper making, hoisting machinery, food, tobacco, etc. the use of these pumps, inverter industry is mainly in electrical equipment, control and obtain the best product performance and output rate is the main purpose of energy saving is different from the 1 in
