Q:It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case): Suggest you in the inverter power installed a frequency converter input filter, try it, feel a bit like electromagnetic interference caused by frequency converter mistakenly stop ah.

Q:How can I learn the converter well?: If you are engaged in maintenance or after sale, you must know the main circuit diagram of the converter, rectifier, filter, inverter. Some electronic components must know, from the main circuit is frequently such as varistors, charging resistance, pressure resistance, no sense of capacitor, filter capacitor, driving circuit of multiple optocoupler such as 2503503120316, this is referred to as the optocoupler and the role, you must know the pin. Because the maintenance process should always be to determine the quality of the device.

Q:Today, I was asked the question, and I also brought it to you to share the following Oh!: Inverter inside the circuit is inverterIt is a control of communication -- direct current -- CommunicationDC alternating current is called inverter

Q:What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.

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:How to deal with the fault Yaskawa inverter GF: See the Yaskawa inverter protection circuit structure, and the other is the same frequency. Over current OL1, OL2 and OL3 fault signals should be current transformers and subsequent current detection and processing circuits and CPUThe fault signals of GF (ground) and OC (load side short circuit) shall be fed directly to the protection circuit of the drive circuit board to feed the CPU. The difference is that at the initial stage of the start-up, the detection module is abnormal, i.e., a fault is reported.If the module is detected in operation, the OC fault is reported. These two kinds of signals, but also revealed such a message: the initial stage, it has not yet established the three-phase output voltage, the load is not running, the actual fault sources should be inverter driving circuit or the IGBT module itself caused by the abnormal, but does not rule out a ground fault load;In operation, there is a very large current, jump OC, the load side of the probability of failure is large, but also over current fault, rather than ground fault. The difference between GF and OC faults and what they mean is really reasonable.

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:What does the base frequency 60Hz represent in the inverter?: The schematic diagram of the basic frequency parameters of the converter is shown in figure.Below the fundamental frequency, the output voltage of the converter varies with the output frequency, and the V/F= constant is suitable for constant torque load characteristics.Above the fundamental frequency, the output voltage of the inverter maintains the same voltage rating of the power supply, which is suitable for constant power load characteristics.

Q:1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Or, ask another question: "under what circumstances can the frequency converter go to the cable of the frequency conversion motor without using shielded cable?" Is there a "no need to use shielded cable" basis?

Q:What is called vector converter?: Vectors and vectors are mathematical methods of vector (vector) analysis, both of which are of the same concept
