Q:What is the main function of the frequency converter on the machine tools?
Where is the difference between soft starter and converter?
Q:How does the frequency converter change the voltage and change the speed of the motor?
In reducing the power frequency, the frequency converter must be reduced at the same time the power supply voltage, this is because, for the asynchronous motor, the phase voltage is proportional to the product of frequency and magnetic flux, when the frequency is reduced, if the voltage is constant, the flux will increase, it is easy to cause the magnetic saturation, excitation current surge, causing the motor to burn.The general frequency converter will automatically adjust the output voltage at the same time as the frequency is changed. What do you need to do without additional operation?.
Q:How do you understand the ramp up (descent) time of the inverter? Thank you!
The reverse is the drop time, or the 0 speed. Water pumps and fan motors are basically not required to change. If it is an emergency stop, it is usually 3 seconds (depending on the frequency converter and process requirements).
Q:What is the difference between frequency converter and servo driver?
The difference between servomotor and frequency conversion motor:Servo system is a closed-loop control system, the inverter usually works in open-loop control, so in terms of speed and accuracy, and can not be compared to the servo drive.The frequency conversion is only one part of the servo, and the servo controls the closed loop precisely on the basis of frequency conversion so as to achieve better results.
Q:What's the frequency converter for? What does it look like?
Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics 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 is frequency conversion? What is the function of frequency converter?
Theoretically, the inverter can be used in all mechanical equipment with electric motor, the motor starts, 5-6 times higher than the rated current, will not only affect the motor service life and consume more power. In the design of the system in the motor selection will leave some margin, the speed of the motor is fixed the same, but in actual use, sometimes running at low or high speed, so the frequency transformation is very necessary. Transducer can realize soft starting and compensating power factor of motor
Q:Should the shielded cable be used for the cable of the transducer to the motor?
When we design the frequency converter to drag the motor load (mostly fan and water pump general machine), we should use shielded cable. We refer to the GB/T21209-2007 "inverter power supply design and performance of cage induction motors in section 9.1.4" guide "motor power cable" "recommended configuration" in the "provisions of more than 30kW motor wiring should adopt the single core power cable or a plurality of grounding wire arranged symmetrical cable. Small power and suitable for wiring, priority is to use multi-core shielded cable." As the PE line symmetrical configuration of the 3+3 inverter dedicated cable, construction is always raised, not wiring, we later too lazy to explain, usually directly with the 3+1 type multi-core shielded cable. From the running situation, the effect is also good.
Q:SIEMENS frequency converter how to manually set the frequency?
Concrete steps are:1, the parameter 700 is the starting signal, the 1 is the panel button starting, and the 2 is the external signal starting;2, the parameter 1000 is the frequency setting value, and the 1 is the panel lifting mark key to change the frequency, and 2 is the external analog signal change.3, the starting signal is set automatically, then the parameter 1000 is 1, the panel is set frequency, and the parameter 1031 is set to 1 so that the frequency value after the change is saved automatically.
Q:What does "frequency" in household appliances mean?
The air conditioner in Japan is gradually changed from pure PWM control to PWM ten PAM mixed control mode. The speed is controlled by PWM, U / F to maintain; when the speed exceeds a certain value, the system will adjust the fixed at the maximum value near, by changing the DC chopper on duty LL, improve the inverter input DC voltage, so as to keep the inverter output voltage and speed is proportional to the area, said PAM area
Q:How to check the frequency converter is there a problem?
Once the inverter has hardware faults, such as rectifier, inverter circuit and so on. The IGBT module may be damaged, and most of the time it will damage the drive components. The most easily damaged devices are the regulator and the optocoupler. Conversely, components such as capacitance, leakage, breakdown, and optocoupler aging can also cause IGBT modules to burn out or frequency conversion, and output voltage is unbalanced. Check if there is a problem with the drive circuit, and compare the resistance of the trigger terminals when the circuit is not switched on. The voltage waveform at the trigger end can be measured when the power is switched on. However, some inverters are not equipped with modules and can not switch on, when the module P end of the series into a false load, to prevent detection, mistakenly touch the originator or other circuit burned module. In this case, the frequency converter has been seriously damaged (by measuring whether the input and output are short circuited), then there should be special technical personnel maintenance, and generally may not re energized, so as not to expand the scope of failure.
