Q: What's the use of switching frequency of converter?: Meanwhile, the switching frequency of the converter is adjusted, and the power loss can be adjusted. Because the switching frequency of power loss and inverter power module IGBT is related with the increase in switching frequency inverter and increasing the power loss, this makes the efficiency drop, two is the power module heating increases, is detrimental to the operation, of course work electric converter pressure is high, the power loss also increase effect.

Q: Knowledge, principle and operation method of frequency converter.: Sinusoidal pulse width modulation (SPWM) of U/f=C with frequency converter control mode:The characteristics of SPWM inverter control way is to control the circuit has simple structure and low cost, the mechanical properties of hardness is also good, can meet the general requirements of smooth speed transmission, has been widely used in various fields of industry. However, when the output voltage is low, the torque is significantly affected by the stator resistance pressure drop, so that the maximum output torque is reduced. In addition, the mechanical characteristics of DC motor can not hard, dynamic torque capacity and static performance is not satisfactory, and the system performance is not high, the control curve will change with the change of the load torque and motor torque, slow response, low utilization rate is not high, due to the stator resistance and the existence of dead time effect of the inverter performance the poor stability, etc.. Therefore, people have studied vector control frequency conversion speed regulation.

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): It should be a frequency converter. Right now, look at the frequency converter output frequency settings, tune, and suggest the next election wide output frequency converter, or simply PLC

Q: What is frequency conversion? What is the function of frequency converter?: Power factor compensation, energy savingThe reactive power will not only increase the heating power loss and equipment, more important is to reduce the power factor of the power grid leads to the decrease of active power, reactive power consumption in a large number of lines, low efficiency, serious waste of equipment, the use of frequency control devices, the inverter internal filter capacitor, thereby reducing the reactive power loss, increase active power grid.

Q: What are the precautions for frequency converter wiring installation?: The control signal line should not be parallel to the power line. If parallel must be used, the shielding wire and one end of the earth must be used.To use 485 or 232 communication, wear a magnetic ring and use twisted pairs.

Q: What does "frequency" in household appliances mean?: The new inverter refrigerator not only the reduction of power consumption, realize mute, and the use of high-speed operation can achieve substantial rapid freezing; in the washing machine, used frequency variable speed control, improve washing performance, washing machine popular in addition to saving energy and silent, still ensure soft clothing washing and other aspects of the introduction of control new content;

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: 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

Q: Frequency converter OC alarm, what's the matter?: And some did not inform you of the inverter fault category, when the OC boot failure, will cause greater danger, then simply caused by surface phenomenon similar to program crashes, such as the P9/G9 series machine when the machine detects INVT, module failure, operationThe H00 character appears on the panel, and all key actions are rejected. Unknown insider will think: program crash, CPU motherboard is a problem.

Q: How to choose frequency converter?: 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
