Q: What's the frequency converter for? What does it look like?: 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. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q: Can the frequency converter 7.5KW take the motor with 11KW?: A motor with variable torque with a constant torque converter, which is permissible. But the load and the motor are constant torque, and the frequency converter is also constant torque, so doing is the small horse cart. No, not recommended. Because the actual click can work continuously load is only 5.5kW, and then big, frequency converter can not stand.

Q: There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: Two inverters with the same frequency and start signal, so that it can be synchronized; another way is to do in front of a given frequency inverter with potentiometer, given analog output signal of the first station to do second machines, it can be done simultaneously; but you have to say clearly what is what specific brand series in order to further clear the inverter parameters, otherwise only vague answers.

Q: What does Ro1c mean on a converter?: Relay output converter dry contact signal, RO1C is the common end and RO1A is closed, RO1B is normally open, this set of contacts is prepared to run the factory setting output signal, power on self-test is completed can run the relay output signal. It can be modified to the output point of the signal such as fault and operation in the twenty-fourth set of parameters.

Q: How can I control the frequency converter with a computer?: RS232 communication can be used to control the frequency converter and other equipment, but there are several problems to be solved:1, frequency converter is generally two wire communication (422/485), so there must be 485/232 or 485/USB conversion.2, software problems, you can use VB, C, and with any of their own familiar with the method of preparation of a control interface, and in accordance with the frequency converter communication protocol written.3, also can buy ready-made configuration software, that saves the trouble of programming and debugging program.4, with computer communication with PLC (currently popular), and then use PLC and frequency converter communication (program is more simple and practical than using VB).

Q: What are the benefits of installing economizer in industrial enterprises?: Frequency converter is a device that regulates the speed of an electric motor by adjusting the output frequency:1. The frequency converter can only reduce the motor speed by reducing the power supply frequency. The application environment is limited and the automatic control function is not available. It can not be used in many load changing occasions;Have a lot of 2 odd harmonics, frequency converter operation, it will seriously affect other equipment life and efficiency, at the same time use but also affect other precision control of the equipment in the factory, such as computer, automatic control system, monitoring system and so on;3 、 frequency converter serial access to the customer's low-voltage power system, the power supply of the customer security risks.

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 is the over-current of the inverter?: When the load is not stable, recommend the use of DTC DTC control mode, because the speed is very fast, the actual torque and flux generated every 25 microseconds a set of precise value after comparator and output torque of the motor flux comparator, optimized pulse selector switch inverter decided to best position, such a system over current. In addition, the speed loop adaptive (AUTOTUNE) will automatically adjust the PID parameters, so that the inverter output motor current is stable.

Q: Delta inverter fault output which parameter is set?: Overvoltage overvoltage fault of inverter DC bus voltage on the tributaries. Under normal circumstances, the average DC inverter three-phase full wave rectifier after. If 380V line voltage calculation, the average DC voltage Ud= = 513V. 1.35 U line in the overvoltage occurs when the DC bus capacitor will be when the charging voltage to about 760V, inverter over-voltage protection action. Therefore, inverter, have a normal range of working voltage, when the voltage of the inverter is likely to damage more than this range, there are two types of common overvoltage.

Q: Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?: Inverter is to realize the speed adjustment of AC asynchronous motor by changing the motor power supply frequency, speed adjustment and balance, load property of the motor does not change with changes in speed, suitable for load adjustment and torque adjustment. Good performance, but high cost.
