- Q:How does the frequency converter fit the brake unit and the brake resistor?!
- The kinetic energy of the motor shaft are much different. The load on the motor shaft, the kinetic energy is different, for example, motor used in cranes, in addition to the kinetic energy, potential energy and objects, should add up to the shaft of the motor, the energy will be consumed in the resistance.
- Q:Can the frequency converter 7.5KW take the motor with 11KW?
- The inverter rated current 7.5 kW is about 17A, the constant current 11KW converter is about 25A 11KW Oh, no-load current is about 8A, 17A is greater than 8A, so the 7.5KW motor with 11KW is no problem, but you have much load, full of motor current 11KW is 25A, 7.5KW certainly do not move with the! That is to say, you can carry 11KW motors running under light loads. Don't worry, the frequency converter will burn down, because the inverter has overload and over-current protection, it can protect your inverter and your motor from damage!
- Q:I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up
- The general frequency converter adopting vector control mode can not only match the DC motor in the speed regulation range, but also can control the torque generated by the asynchronous motor. The vector control method is based on the parameter of controlled asynchronous motor accurately, some general inverter needs accurate input parameters of asynchronous motor when in use, some general inverter needs to use the speed sensor and the encoder. In view of the motor parameters may change, will affect the performance of inverter for motor, the model of vector control of induction motor parameter automatic detection, automatic identification, adaptive function has the general inverter, can automatically to motor parameter identification before with the function of the general inverter for normal operation in the asynchronous motor, and adjust the control related parameters in the algorithm according to the identification results, thus effectively to ordinary asynchronous motor vector control.
- Q:What does Ro1c mean on a converter?
- 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 basis of the frequency converter to choose?
- 1, brand, mainly for cost control2, performance, overload, function, reliability,3, load characteristics, constant torque, square torque or special load (determine the length of the cable of the load motor)4, environmental aspects: temperature, humidity. Altitude.These are the needs of attention when type selection.The last point is the most important, when choosing type, remember that the motor power can not be selected, must be selected in accordance with the motor current.
- Q:What is the working principle of elevator frequency converter?
- Yaskawa 616G5 transducer current vector in the world as one of the inverter control, speed range to reach 1:1000, the control accuracy of 0.02%, with the starting torque at zero speed can reach 150% characteristics. In particular, Yaskawa unique all fields, automatic torque boost function can get comfort and good stability in the lift drag in.G5 can accept controllers such as multi speed frequency command PLC or analog voltage and current instruction; can adapt to all kinds of motor vector control and self-learning to obtain good characteristics; low speed starting smoothly excellent reliability and high cost of hardware.
- Q:What does the RUN key on the inverter mean? How do you use it?
- According to the actual needs of the motor to provide the required power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are many inverter protection functions, such as over-current, overvoltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.
- Q:What's the use of switching frequency of converter?
- Switching frequency is generally the default value of the system is better, do not recommend any adjustments, generally only when problems are encountered, will be adjusted, because:The higher the switching frequency of the converter, the smoother the output waveform; the lower the switching frequency of the converter, the worse the output waveform. Switching frequency, to put it bluntly, is chopping, assuming we cut the sine wave for 100 and 1000, and that must be the combination of 1000 segments, the waveform is more like a sine wave, this should be understandable.
- Q:Can the motor with frequency converter directly wave the insulation?
- The use of motor inverter drive, if the measurement will not disconnect the motor and inverter, tramegger issued a "high voltage" will spread through the winding inverter inside, will lead to some components breakdown within the inverter a damaged, because some components although the internal current is higher but the degree of pressure will be very limitedTherefore, in shaking the test of the use of inverter motor insulation, the inverter and motor connection is broken after the start, you can ensure that the frequency converter will not be damaged.
- Q:Schneider 303 4KW frequency converter F 013 trouble shooting method
- If the converter is overloaded, it is recommended to check the set acceleration time and whether the load is blocked or not.
