Q: What are the modes of operation of a frequency converter?: If the inverter is still protected within a specified period of time, the running curve of the starting P should be changed, from the straight line to the S, U, or reverse, S, and U lines. When the motor load is large, a longer start stop time should be adopted, and the operation curve type should be set according to its load characteristics. 41 If the inverter is still running failure, try to increase the maximum current protection value, but can not cancel the protection, there should be at least 10% to 20% of the protection margin. 51, if the frequency converter operation failure or replacement, should be replaced by a larger power converter. 61 If the inverter drives the motor in the start-up process can not reach to the preset speed, there may be two cases:

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: How does the frequency converter change the voltage and change the speed of the motor?: The inverter does not change the voltage to adjust the speed of the motor. Under the premise of constant voltage, the frequency of the alternating current is changed to adjust the speed of the motor. Typically, at the frequency of 50Hz, the synchronous speed of the quadrupole motor is 1500 rpm, and if the frequency is increased to 60Hz, the synchronous speed should be 1800 rpm; if it falls to 40Hz, the synchronous speed should be 1200 rpm. In the limited frequency range, the power is constant, the higher the speed, the smaller the torque, the lower the speed, the greater the torque. Formula for speed calculation (Rev / min):60 seconds * / log polar frequency. The middle pole of a pair is 2 poles of 1 pairs, i.e., the quadrupole motor is 2 pairs of magnetic poles.The frequency of the converter is stepless, continuous and adjustable, so the speed of the motor is continuously adjustable in a certain range.

Q: What are the key points of frequency converter maintenance?: Frequency converter daily patrolDo the inverter daily inspection and inspection work, inspection contents mainly include: ambient temperature, humidity is required, ventilation windows is good; the inverter air inlet and outlet is blocked by dust or too much dust; inverter operation parameter is normal, there is no alarm; cabinet fan the operation is normal; if there is abnormal sound or vibration transducer; capacitor whether overheat.

Q: What is frequency conversion? What is the function of frequency converter?: Frequency conversion energy savingThe frequency converter energy saving mainly displays in the fan, the water pump application. In order to ensure the reliability of production, all kinds of production machinery in the design and use of power driven, have left a certain amount of surplus. When the motor can not run under full load, in addition to the power driven requirements, the excess torque increases the consumption of active power, resulting in waste of energy. Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water supply, its high input power, and a large amount of energy consumption in the process of the baffle and valve closure. When using the variable frequency speed regulation, if the flow requirements are reduced, by reducing the speed of the pump or fan can meet the requirements.

Q: What does Ro1c mean on a converter?: 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.

Q: Why does the frequency change when the frequency converter regulates the frequency?: That's for sure. The curve of voltage and frequency should be set according to the load condition, but after the rated frequency of the motor, the voltage is kept at the rated voltage

Q: I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: Reasonable wiring: 1. principle - control line as far as possible from the input and output lines.2. non parallel principle - the control line should be crossed as far as possible in the space and the input and output lines, preferably the verticalStraight crossing, not parallel.3. phase principle - two control lines are adjacent to each other.

Q: Frequency converter OC alarm, what's the matter?: The frequency at which the OC fault occurs in all faults of the inverter may be the highest and the most frequent. In the process of starting the alarm, in the process of stopping the alarm, alarm in operation, so that power on the alert, and even with other fault codes or currentIndirectly tell you that there is a OC fault in this inverter!

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
