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: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 does the frequency converter change the voltage and change the speed of the motor?: Change the motor frequency converter, V/F control mode in changing the motor frequency at the same time according to the proportion of changing the voltage of the motor, the speed and frequency of the motor is proportional to the relationship, so it changes the motor speed.

Q:Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?: The electronic governor for single-phase motor, by changing the access winding resistance and capacitance to adjust the motor speed, the speed of the output power supply for power has not changed, so the speed is not a kind of energy-saving control methods, such as the electric fan like for home.

Q:First of all, I would like to achieve the frequency converter with motor static linear acceleration, high-speed linear deceleration stop processFirst question: I say kind of situation, three paragraph speed start, 0.1hz---> high 30hz-->0.1hzSecond problem: manual speed instruction 1, speed 2, speed 3 instruction instruction I want to use PLC to control three speed motor with three reverse contact dry. I understand speed instruction 1 is switched on (2, 3 connected) transmission section set the frequency with the frequency segment set 0HZ123 AssociationThird questions: manual section, speed command, main frequency and STEP1-STEP7 stage setting frequency, I use PLC analog to the frequency main frequency setting, plus and deceleration, STEP1-7 are set 0, can achieve what I wantInitial contact frequency converter, home pointing: Three speed motor static acceleration setting speed, then slow down to stop, in fact, frequency case should be motor frequency 30Hz set frequency converter 30Hz, and then to start and stop signal requirements (plus or minus speed, according to the scene set P-10 P-11)

Q:The functions of frequency converter and UPS are similar, especially the power frequency UPS?: The obvious difference between the two:1, the former output amplitude and frequency adjustable, the latter output is a single fixed amplitude, frequency;2, the former does not use batteries, and the latter requires batteries.

Q:The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: Overvoltage prevention measures: due to over-voltage causes are different, so the countermeasures are not the same. For overvoltage in parking, if there is no special requirement for parking time or position, it can be solved by using extended frequency converter, deceleration time or free parking. The so-called free parking, that is, the frequency converter will switch off the main switch, so that the motor free sliding stop. If the parking time or parking position have certain requirements, then the DC brake (DC brake) function can be used

Q:What's the function of this brake unit?: When the motor is fast stopping, the motor will feedback the energy to the converter, causing the DC bus voltage to rise or even damage the IGBT. Therefore, it is necessary to use the braking unit to save the part of the energy to protect the converter.Inverter braking a lot, can refer to:

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:What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: Inverter environment temperature(1) working temperature. The use of frequency converter should pay attention to the environmental matters, the internal is high-power electronic components, is easily affected by the operating temperature, the product is generally required to be 0~55 degrees, but in order to ensure safe and reliable work, when usedShould be considered under the best control in 40 DEG C. In the control box, the inverter shall be installed on the upper part of the box, and strictly comply with the installation requirements of the product manual, absolutely not allowed to sendA heat element or a heat generating element is mounted close to the bottom of the inverter.
