Q: At the base block Yaskawa inverter is what reason?: Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base

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.

Q: What are the key points of frequency converter maintenance?: 1., regular cleaningAlways check the frequency converter regularly and keep the environment clean and dry. It is strictly prohibited to place sundries near the frequency converter, and someone should regularly clean the frequency converter, blow it out, keep the cleanliness of the converter and the ventilation of the air duct.2. treatment methodsIf it is found within the inverter or radiator plate dust and debris falling into, should promptly use compressed air to blow off. Clean air filter, cooling air duct and interior dust. When it is found that the conductor and insulator have corrosion, it should be promptly cleaned with alcohol.For continuously running inverters, the running state can be visually checked from outside. Periodically inspect the converter and check if there is any abnormality when the converter is running. The following tests should normally be carried out:

Q: Can the frequency converter 7.5KW take the motor with 11KW?: A motor with variable torque with a constant torque converter, which is permissible. But the load and the motor are constant torque, and the frequency converter is also constant torque, so doing is the small horse cart. No, not recommended. Because the actual click can work continuously load is only 5.5kW, and then big, frequency converter can not stand.

Q: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Do not use shielded cables have several conditions: the first is from the inverter to motor wear long steel pipe laying cable. Second is the frequency converter to the motor cable line routing (cable bridge, cable ditch), there is no analog signal cable or other weak signal cable. Otherwise, from the debug runtime, if the inverter cable cable line motor and analog signal very close, even if the analog signal shielded cable control cable when the motor running is still very obvious interference of analog signals, especially large power motor.

Q: Check the fault information is the power supply voltage instability, but other inverters are running well, what is the matter? Will there be any other parameters are not set correctly, thank you!: This example is obvious, due to undervoltage, to find the problem of power, the first to exclude external problems, from the inverter inside to find the reasons.

Q: What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: General environment temperature: inverter is an electronic device, containing electronic components, electrolytic capacitors, etc., so the temperature has a greater impact on its life. The environment of general inverter operating temperature of ~+50 DEG C - General requirements, if it can reduce the operation temperature of inverter, prolongs the service life of the transducer, stable performance. So heat dissipation is very important.

Q: What does "EPCU" mean in a frequency converter?: This is the frequency converter BlueOcean Huateng, they said this code external signal interference, you are not the power line and the signal line to go ah, check the external line, then no problem on the phone to the factory

Q: Why does harmonic generator produce harmonic? What's his working principle?: Harmonic generation mechanism of inverter inputThe main circuit of inverter is composed of AC-DC-AC, external input 380V/50Hz power supply through the three-phase bridge rectifier, a DC voltage, AC voltage by the capacitor filter and high power transistor switching element for variable frequency inverter. In the rectifying circuit, the input current waveform is a rectangular wave irregular waveform, according to Fu Liye series is decomposed into fundamental and harmonics, the harmonic frequency is usually 6N + 1 harmonic, the harmonic interference input power supply system. If the reactance of the supply side is sufficiently small and the commutation overlap angle can be neglected, then the n order harmonic is the 1/n of the fundamental current.

Q: I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: You can try using the following methods:Solution of interference caused by circuit coupling:The PLC and monitoring equipment are powered by isolated transformers.
