- Q:What do you mean by the capacity of the inverter and the capacity of the motor?
- Capacity can be understood as active power + reactive power, such as the capacity of 100KVA inverter, is not 100KW motor,
- 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 is to change the power supply voltage transformer, but also has some other functions, such as isolation transformer, is to play a protective role, he doesn't play the role of the transformer, the transformer that you are, in what place, or auto? Is it installed in the distribution panel? If you say is likely to auto start with the inverter itself is changing the power supply of the power frequency, when the electric motor is often used in some special occasions will be used! Because the most convenient way to change the speed of the motor is to change the frequency of the power supply!
- 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:Today, I was asked the question, and I also brought it to you to share the following Oh!
- Inverter inside the circuit is inverterIt is a control of communication -- direct current -- CommunicationDC alternating current is called inverter
- 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:What's the difference between universal inverter and fan pump converter?
- In practice, the production machinery is often divided into three types: constant torque load, constant power load and fan, pump load.Constant torque load:The load torque TL is independent of the speed n, and the TL remains constant or almost constant at any speed. For example, conveyor belts, mixers, extruders and other friction loads, as well as cranes, hoists and other potential loads are constant torque load.When the inverter drives the load with constant torque, the torque at low speed is large enough and has enough overload capacity. If it is necessary to operate at a low speed, the cooling capacity of the standard asynchronous motor should be taken into consideration, so as to avoid the excessive temperature rise of the motor.
- Q:Heating inverter commissioning steps
- And carry on the test run 1. manual operation of the frequency converter panel running stop, observe the motor running process and the frequency converter display window, to see if there is abnormal phenomenon. 2. if the P is started and the over-current protection is stopped in the motor, the acceleration P deceleration time should be reset. The acceleration of the motor during acceleration and deceleration depends on the acceleration torque, while the frequency change rate of the inverter during the start and braking is set by the user. If the inertia of motor or motor load change, speed or deceleration rate according to frequency change preset when possible acceleration torque is not enough, resulting in motor stall, motor speed and the inverter output frequency coordination, thus causing overcurrent or overvoltage. Therefore, it is necessary to set acceleration and deceleration time according to the inertia and load of the motor, so that the frequency change rate of the converter can be coordinated with the speed change rate of the motor.
- Q:Frequency converter, fault, contact action
- Frequency converter is the application of frequency conversion technology and micro electronics 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. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.
- Q:What are the possible causes of frequency hopping overload?
- The meaning of inverter overload protection is that the output current of the inverter continues to exceed the rated current, but it has not exceeded the transient flow point, and the general duration is defined as 1min. The general overload constant torque converter is 150% 1min, variable torque converter is generally 110%120%/1min.
- Q:Why does the frequency converter cause interference?
- (a) PE converter 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.
