Q: High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: According to the classification of link Transformation: (1) the AC-DC-AC converter is the first AC into DC rectifier through, and then transformed into the frequency DC voltage adjustable AC inverter, also known as indirect, is currently widely used general-purpose inverter. (2) can be divided into cycloconverter, is directly converted into AC voltage adjustable frequency AC, also known as direct inverter DC power supply according to the classification of properties: (1) the voltage type inverter voltage type inverter is characteristic of DC link energy storage device using a large capacitor load reactive power will be it is to buffer the DC voltage, DC power supply is relatively stable, smaller internal resistance and the equivalent voltage source, so that the voltage type inverter, are often used for load voltage changes in the larger situation. (2) current inverter current type inverter is characterized by large DC link inductance as a storage buffer of reactive power, which changes the current control, the voltage is close to sine wave, because the DC resistance is large, so that the current source converter (current). The characteristics of current source inverter (advantages) can restrain the load current is frequent and rapid changes.

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: Today, I was asked the question, and I also brought it to you to share the following Oh!: The inverter (power converter, Power Inverter) is a kind of DC12V can be converted to DC and AC220V AC power the same, for general use of electrical appliances, power converter with a convenient car.

Q: How do you understand the ramp up (descent) time of the inverter? Thank you!: The ramp up time is to start from the 0 speed, inverter, running to reach the given speed (for example: 1420) the time required, in general, the longer the time, the frequency converter and motor impact is small. In the actual work process, according to process requirements to set the length of time. (more than 10-15 seconds) or so, if it is a pump or fan motor, do not need to change its rise time, the default can.

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: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: 1. motor speed control will not be accurate2. the working current of the motor may become larger, and the motor will be burnt out3., excitation what will change, but also may cause the motor heating, burnout, will also reduce the efficiency of the motor;4. may also burn the inverter.5. motor output may be affected.

Q: How to maintain the frequency converter will not damage, or regular maintenance?: 1. cooling fan, inverter power module is the most serious heating device, the continuous heat generated by the work must be promptly discharged, the general fan life of about 10Kh-40Kh. According to the continuous operation of converter for 2-3 years, it is necessary to replace the fan2. filter capacitor, intermediate circuit filter capacitor: also called electrolytic capacitor, its main function is to smooth the DC voltage, absorb the low-frequency harmonic in dc.

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: There is no doubt that the sound we hear is the sound produced by mechanical vibrations. When the inverter is idle, just as upstairs, it says only a slight noise from the fan, but there is a squeal when loaded

Q: Heating inverter commissioning steps: The no-load connection test of the frequency converter will connect the grounding terminal of the frequency converter to the ground 1. 2 the power input terminal of the frequency converter is connected to the power supply through the leakage protection switch. 3 check the frequency converter display window factory display is normal, if not correct, should reset, or request exchange. 4 familiar with the operation key of frequency converter. The inverter has run in general (RUN) and stop (STOP), programming (PROG), P (DATAPENTER), the data confirm the increased (UP, 3), reduce (DOWN, 6) and other key definitions of different inverter operation keys are basically the same. In addition, some inverters also monitor (MONITORPDISPLAY), reset (RESET), inch movement (JOG), shift (SHIFT) and other functional keys.

Q: What are the basis of the frequency converter to choose?: 1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。3. when the load is large, the braking unit and the braking resistor should be selected simultaneously.4. check the motor nameplate current rating (no nameplate rated current). The rated current of the inverter is greater than the maximum running current of the motor
