- Q:Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?
- When the high speed motor is driven by a transducer, the higher the higher harmonic is, the higher the output current value is due to the small reactance of the high speed motor. Therefore, the type selection of frequency converter used in high speed motor is slightly larger than the selection of ordinary motor.And if you want a long cable converter operation, this time to take measures to curb the influence of long cable on the coupling capacitor, to avoid the shortage of inverter output, so in this case, the frequency converter to enlarge the capacity of a file or install the output reactor in the inverter output.And for some special applications, such as high temperature, high altitude, at this time will cause the inverter derating, frequency converter to enlarge the capacity of a block.
- Q:PT100 temperature patrol instrument, when the converter is not open, the measurement is normal. Once opened, it shows completely disorder, and sometimes there are puzzling characters. How can I solve this problem? Please enlighten master!
- If only the temperature measurement fluctuations, as the temperature is slow change, the filter is more effective way, the filter can use a passive RC low-pass filter, and then connected to the patrol instrument on the terminal can.
- Q:What are the contents of frequency converter maintenance?
- Replacement of spare partsThe inverter consists of various components, some parts of the work for a long time after its performance will gradually decrease, aging, which is the main reason of inverter fault, in order to ensure the normal operation of equipment for a long time, the device should be replaced regularly:
- Q:What are the basis of the frequency converter to choose?
- 1, brand, mainly for cost control2, performance, overload, function, reliability,3, load characteristics, constant torque, square torque or special load (determine the length of the cable of the load motor)4, environmental aspects: temperature, humidity. Altitude.These are the needs of attention when type selection.The last point is the most important, when choosing type, remember that the motor power can not be selected, must be selected in accordance with the motor current.
- Q:What does "G" and "P" mean in the converter model?
- G stands for constant torque, usually overloadedP stands for torque change, usually light load type
- Q:What is the over-current of the inverter?
- The reason of the frequency converter itself:?1, parameter setting problem: for example, the acceleration time is too short, the PID regulator's proportion P, the integral time I parameter is unreasonable, the overshoot is too big, causes the frequency changer output current oscillation.?2 、 frequency converter hardware problem:
- Q:High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?
- Specific answer to your question: 1, high voltage inverter: This is based on the input voltage level terms. Generally speaking, 10KV is more than 6KV voltage high voltage frequency converter, 1140V, 3300V in general is medium (some people also called it the high voltage level of 380V, 660V), 480V, commonly called the low-voltage inverter; 2, pump inverter: This is according to the type of application in terms of. Fan pump inverter mainly refers to the frequency converter used to drag fans, pump load, the main feature is light load, simple application.
- Q:What does 0L1 stand for?
- The acceleration is generally overloaded during acceleration. Load inertia is too large, the inverter power is small, or the acceleration time is too short, and so on
- Q:Where is the frequency converter used?
- From the industry application: 1, chemical, petroleum, electric power, municipal, mining, cement, water treatment and other industries, the main use of 380V/690V/6-10kv inverter, these industries have a large fan pump power, the original AC operation, high energy consumption, the use of inverter speed regulation can be obtained after large energy saving, so it is the the main users of the main high power 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.
