Q:What's the difference between universal inverter and fan pump converter?: In practice, the production machinery is often divided into three types: constant torque load, constant power load and fan, pump load.Constant torque load:The load torque TL is independent of the speed n, and the TL remains constant or almost constant at any speed. For example, conveyor belts, mixers, extruders and other friction loads, as well as cranes, hoists and other potential loads are constant torque load.When the inverter drives the load with constant torque, the torque at low speed is large enough and has enough overload capacity. If it is necessary to operate at a low speed, the cooling capacity of the standard asynchronous motor should be taken into consideration, so as to avoid the excessive temperature rise of the motor.

Q:Can the frequency converter 7.5KW take the motor with 11KW?: The inverter rated current 7.5 kW is about 17A, the constant current 11KW converter is about 25A 11KW Oh, no-load current is about 8A, 17A is greater than 8A, so the 7.5KW motor with 11KW is no problem, but you have much load, full of motor current 11KW is 25A, 7.5KW certainly do not move with the! That is to say, you can carry 11KW motors running under light loads. Don't worry, the frequency converter will burn down, because the inverter has overload and over-current protection, it can protect your inverter and your motor from damage!

Q:Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: When detecting the phase - lacking circuit, the phase - blank board is directly tested, and the PL signal on the drive board is normal. Normally, the PL is low, the phase is Fang Bo, and the power is high when the power is switched off. It is important to note that the PL signal output by the drive board or the phase blank panel is not sent to the CPU after the level switch has been passed on the main control board, and it should be noted that the fault is caused by the main board or the missing phase board during maintenance.

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:What do you mean by the capacity of the inverter and the capacity of the motor?: Capacity can be understood as active power + reactive power, such as the capacity of 100KVA inverter, is not 100KW motor,

Q:What does "EPCU" mean in a frequency converter?: This code indicates external signal interference.It is possible that the power line and the signal line are coming together to check that the ground of the converter is ready.If not yet, that can only be considered in the inverter output end of the inverter output filter, or inverter output reactor to try.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.

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.

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:Why does harmonic generator produce harmonic? What's his working principle?: Harmonic generation mechanism of converter outputIn the inverter output loop, the output current signal is a pulse waveform modulated by the PWM carrier signal. For GTR high-power inverter component, the carrier frequency of PWM is 2-3kHz, while the maximum carrier frequency of IGBT high-power inverter component is 15kHz, PWM. Similarly, the output loop current signal can also be decomposed into only the fundamental wave and other harmonics.

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.
