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?: When the high speed motor is driven by a transducer, the higher the higher harmonic is, the higher the output current value is due to the small reactance of the high speed motor. Therefore, the type selection of frequency converter used in high speed motor is slightly larger than the selection of ordinary motor.And if you want a long cable converter operation, this time to take measures to curb the influence of long cable on the coupling capacitor, to avoid the shortage of inverter output, so in this case, the frequency converter to enlarge the capacity of a file or install the output reactor in the inverter output.And for some special applications, such as high temperature, high altitude, at this time will cause the inverter derating, frequency converter to enlarge the capacity of a block.

Q:How does the PLC process the inverter output signal?: Frequency converter frequency signal will actually be converted to 4-20mA signal output, access to the PLC AI channel, SIEMENS 200 PLC, some CPU module comes with AI input, but also has a dedicated AI expansion module. What's left is software programming

Q:How to maintain the frequency converter will not damage, or regular maintenance?: 1. cooling fan, inverter power module is the most serious heating device, the continuous heat generated by the work must be promptly discharged, the general fan life of about 10Kh-40Kh. According to the continuous operation of converter for 2-3 years, it is necessary to replace the fan2. filter capacitor, intermediate circuit filter capacitor: also called electrolytic capacitor, its main function is to smooth the DC voltage, absorb the low-frequency harmonic in dc.

Q:Can 220V use frequency converter to drive three-phase motor with 380V?: Can not. The inverter is not step-up, single-phase 220V AC frequency converter into it is three-phase 220V AC motor is connected if your star angle connection can be changed, if the corner there's no way, after the motor power will be reduced about 4/10.

Q:What's the use of switching frequency of converter?: Meanwhile, the switching frequency of the converter is adjusted, and the power loss can be adjusted. Because the switching frequency of power loss and inverter power module IGBT is related with the increase in switching frequency inverter and increasing the power loss, this makes the efficiency drop, two is the power module heating increases, is detrimental to the operation, of course work electric converter pressure is high, the power loss also increase effect.

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 role does input and output reactor play?: Enter the reactor to suppress the surge voltage and surge current protection, frequency converter, and prolong its service life and prevent the harmonic interference, at the same time as the speed control inverter adopts frequency conversion mode, so often produce harmonics and waveform distortion in the speed, will affect the normal use of equipment, therefore, should be installed in a line choke the input end of the inverter can improve the power factor and harmonic current suppression filter, harmonic voltage and harmonic current, improve the quality of power grid.

Q:Delta inverter fault output which parameter is set?: Overload overload fault include frequency overload and overload. The electric machine may be accelerated in short time, the DC brake is too large, the grid voltage is too low, the heavy load causes. Usually by extending the acceleration time and prolong the braking time, check the power voltage. The heavy load, the motor and inverter can not drag this may be due to mechanical load, lubrication is not good. The former must replace high power motor and inverter; if the latter want to overhaul production machinery.

Q:What is the TTK converter produced?: Characteristic：Compact structure design, flexible installation, advanced control algorithm: space voltage vector control technology, power failure restart, automatic voltage adjustment, dead time compensation, energy saving operation,The main and auxiliary setting, built-in PID, simple PLC, oscillating frequency and zero frequency difference, length control, precision control requirements; design and test in accordance with international standards, to ensure the reliability of the product; choose rich accessories.

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.
