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: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:How to choose frequency 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 is the difference between SIEMENS inverter and built-in filter?
The filter is used for electromagnetic interference protection. Not only for the protection of electrical equipment, but also for the use of environmental protection. Inverter application environment is very extensive. Industry, light industry, commerce, civil, etc.. So the level of electromagnetic protection is also different.By the way。 If you disconnect the converter. See a coil on a board. That's the built-in filter. If you don't have it, you don't have that coil.
Q:What is the difference between a frequency converter and a saver?
The input and output filter and the DC reactor in the economizer can prevent the harmonic produced by the converter and cause the pollution of the power grid and the surrounding electricity environment.3 、 no disturbance power supply / electricity saving conversion system is beneficial to ensure that the customer load can be put into use quickly when the machine fails, and the normal production of the customer will not be affected. At the same time, the protection function of the economizer is perfect, and it has the protection function of over voltage, under voltage, over current, over temperature and surge resistance.4, reactive power compensation, improve the power factor of the system, reduce reactive power loss.
Q:Frequency converter size selection
You refer to the type and parameters of the frequency changer to select.
Q:What do you mean by the capacity of the inverter and the capacity of the motor?
Because the motor consumes active power and consumes reactive power, and the reactive power is also occupied, the motor with 70KW can only be usedThe power is known to everyone
Q:Hello everyone, I was doing fine tuning, ask inverter carved machine always ranging from the time jump out ah?
It should be a frequency converter. Right now, look at the frequency converter output frequency settings, tune, and suggest the next election wide output frequency converter, or simply PLC
Q:What does the brake unit on the inverter mean?
The normal asynchronous motor in power loss, but also because of the inertia and load rotor rotate continuously for a period of time, at this time, due to the current of the rotor motor will still exist, such as the generator, sent to the power supply current. When a short circuit fault occurs, the motor also provides feedback current.
Q:Synchronous operation of two inverters,
Two start with frequency conversion. The frequency converter is controlled by a potentiometer, and the analog output signal (AO.GND) is sent into the converter and connected to the AI.GND port of the converter. If the pulse port can also be connected to the pulse port.
