Q: The functions of frequency converter and UPS are similar, especially the power frequency UPS?: The obvious difference between the two:1, the former output amplitude and frequency adjustable, the latter output is a single fixed amplitude, frequency;2, the former does not use batteries, and the latter requires batteries.

Q: Can the frequency converter 7.5KW take the motor with 11KW?: No, in general, the selection of frequency converter is larger than that of motor, that is 11W frequency converter with 7.5KW motor.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. Because the actual click can work continuously load is only 5.5kW, and then big, frequency converter can not stand.

Q: What is frequency conversion? What is the function of frequency converter?: Frequency conversion:1, the frequency conversion is to change the power supply frequency, thus adjust the load, play a role in reducing power consumption, reducing the loss and prolonging the service life of the equipment. Frequency conversion.2, the core of frequency conversion technology is frequency converter, through the power frequency conversion to achieve automatic adjustment of motor speed rate, the fixed frequency of 50Hz is changed to 30 - 130 Hz frequency. At the same time, the utility model makes the voltage range of the supply voltage reach 142 - 270V, and solves the problem that the voltage of the power grid is unstable, which influences the work of the electric appliance. The technique of alternating current control by changing the frequency of alternating current is called frequency conversion technology.

Q: What are the precautions for frequency converter wiring installation?: First understand the instructions, do not take the control line wrong, power line into the wire outlet is connected, you can debug it

Q: What are the differences between the two quadrant and the four quadrant of the inverter?: The four quadrant inverter can not only drag the motor forward and backward, but also convert the kinetic energy of the motor idle time into electrical energy and feed it back to the power grid. Cause the motor to operate in the generator. Often used in some promotional occasions.

Q: Where is the frequency converter used?: In these industries, the use of small and medium power converters more, 220V/380V as its main model. Of course, the auxiliary facilities in these industries still have fans, pumps and inverters, but they don't use much.

Q: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: 1. motor speed control will not be accurate2. the working current of the motor may become larger, and the motor will be burnt out3., excitation what will change, but also may cause the motor heating, burnout, will also reduce the efficiency of the motor;4. may also burn the inverter.5. motor output may be affected.

Q: 5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?: Excessive temperatureIn addition there are high temperature transducer fault, such as the occurrence of a high temperature alarm, after checking the temperature sensor is normal, may be caused by the disturbance, faults can be shielded, also should check the ventilation fan and inverter. For other types of failures, it is better to contact manufacturers for quick and feasible solutions.

Q: How do you set the frequency with panels?. What are the specific steps?: Frequency converter is the application of frequency conversion technology and micro electronics 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: I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up: No PG vector control (motor with encoder), set the motor parameters self-learning, rated voltage, rated current, fundamental frequency (50, 33.3, 20 HZ motor should pay attention to what kind of), pole number, frequency speed, rated power, the maximum output frequency, etc., set the end after the rotation form self-learning (motor without load), or stop shape self-learning. Even the self-learning control model parameter to the external terminal control, analog voltage is changed to external control, can be CNC, PLC or PC to control its operation.
