Q:How does frequency converter realize variable frequency speed regulation?: The technique of alternating current control by changing the frequency of alternating current is called frequency conversion technology. The frequency converter usually uses the on-off function of the power semiconductor device to change the power frequency power to another frequency energy control device.

Q:What is the difference between SIEMENS inverter and built-in filter?: SIEMENS built-in filter optional three. Class a EMC filter. B class EMC filter. LC/ sine filter.Power 110KW to 250KW converter, optional external or built-in level a filter,The power 7.5KW to 15Kw converter, in addition to additional B class EMC filter, can be equipped with a class EMC filter.The LC/ sinusoidal filter can effectively suppress the rise of voltage and capacitance charge / discharge current in the variable frequency drive. But there are many restrictions: only V/F is allowed. FCC control mode. To comply with the 15% drop capacity, the output frequency limit is 150HZ, and only allowed to operate at the 4KHZ pulse frequency. In operation and debugging, the LC sinusoidal filter must be connected to the motor.

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:I am in control of the equipment: the same mechanical movement, this needs a motor drive, a frequency converter drive. Now it's due to the mechanical location: buy two units of the same motor. Can you use a converter in parallel to drive it? Please point out! Thank you (frequency converter: the power of Schneider is equal to the sum of two motors): I suggest you use SIEMENS's 6SE70 model converter (I used this to do a lot of track debugging, it's really easy to use and not easy to go wrong)Communication with the PLC, as long as the Profeibus link on the good, communication and control characters are very good setRemark: a multi motor controlled by a transducer must start and stop at the same time, and the control speed is the same

Q:How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?: Motor 90KW, frequency converter, 90KW can be applied, but the frequency can not exceed the rated value of the motor. There are some occasions to live and use the frequency converter to speed up the motor, so it should be chosen a little larger, otherwise the inverter will be more loaded.

Q:Why do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?: The frequency changer changes the frequency of alternating current. The transformer changes the voltage.Take a closer look at the materials on the electrician.

Q:What's the function of this brake unit?: 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:The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you: The input is AC 50Hz sine wave output frequency variable, but still want to be sinusoidal. But due to various reasons such as the efficiency and control it is not directly output sine wave. It is the original inverter with high frequency sine wave modulation is Fang Bo, will be on the radio. As the modulation principle this is also called the square wave carrier. Between hundreds to thousands of HZ. In the range of our hearing. When it can be produced by mechanical vibration equipment such as reactors will sound when conducting ]. This is the voice we heard.The frequency of electromagnetic waves is high, that is, the corresponding mechanical vibration can occur, and it is also the frequency that the human ear can not hear, so it can not be heard

Q:Where is the difference between soft starter and converter?: The utility model is mainly composed of a three-phase anti parallel thyristor connected in series between the power supply and the controlled motor, and an electronic control circuit thereof. Different methods are adopted to control the turn-on angle of the three-phase anti parallel thyristor, so that the input voltage of the controlled motor varies according to different requirements, and different functions can be realized. 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. Soft starter and converter

Q:What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: Vibration and shock. The control cabinet equipped with frequency converter will cause bad electrical contact when subjected to mechanical vibration and shock. At this time, in addition to improving the mechanical strength of the control cabinet, away from the vibration source and shockShock source should also use shock rubber pads, fixed outside the control cabinet and internal electromagnetic switches and other parts of the vibration generated. After running for a period of time, the equipment should be inspected and maintained.
