Q: What does 0L1 stand for?: Inverter 0L1 stands for frequency converter fault code: OL1: motor overload (OL1) fault for the output current exceeds the overload capacity of the motor, then need to reduce the load.

Q: Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: Frequency rising problem of frequency converter;Voltage matching; the rated voltage of the converter is in line with the rated voltage of the load.Current matching; ordinary centrifugal pump, the rated current of the converter is in line with the rated current of the motor. For special loads, such as deep water pumps, it is necessary to refer to the motor performance parameters and determine the current and overload capacity of the inverter with maximum current.Torque matching; this situation may occur when a constant torque load or a deceleration device.

Q: How does frequency converter realize variable frequency speed regulation?: Frequency conversion means changing the power supply frequency.The core of frequency conversion technology is frequency converter. It can automatically adjust the speed of motor operation by changing the frequency of power supply, and change the fixed frequency of 50Hz to 30 - 130 Hz frequency. At the same time, it also makes the voltage range of power supply reach 142 - 270V, and solves the difficult problem of electrical work because of the instability of the grid voltage.

Q: Ask, what is the ratio of frequency converter?: Connect the air switch, the power supply, check the wiring is correct, close the air switch, turn on the frequency converter, and the digital tube shows 0.Turn off the power, the power indicator light is extinguished, then connect the motor, on-off switch, tone potentiometer, trimmer potentiometer, inching button, frequency meter (0 ~ 10V voltage meter), three sets of inverter and motor proportion of joint operation, the inverter and the motor grounding terminal reliable grounding, and carefully check.

Q: Why does harmonic generator produce harmonic? What's his working principle?: Is the inverter harmonics in converter running, need to input power supply of high power diode rectifier (or transistor / inverter module) of inverter; in the inversion process, the high-order harmonic generation in the input / output circuit; inverter harmonic to the power supply system, load and his nearby electrical equipment interference.

Q: Can 220V use frequency converter to drive three-phase motor with 380V?: Can not. The inverter is not step-up, single-phase 220V AC frequency converter into it is three-phase 220V AC motor is connected if your star angle connection can be changed, if the corner there's no way, after the motor power will be reduced about 4/10.

Q: What is the difference between inverter energy consumption braking and motor energy consumption braking?: A direct current is generated in the stator winding so that a fixed magnetic field is generated. At this point, the rotor cuts the magnetic field lines in the direction of rotation, resulting in a braking torque. Because the braking method is not like regenerative braking (using frequency converter), the energy generated by braking is fed back to the grid, but the energy is dissipated by the motor alone, so it is called energy consumption braking. The utility model is also used for braking by direct current in the stator winding, so the energy consumption braking is called DC injection braking. By using the backward switch Q to return the point voltage back to the grid, the armature current will become a copy, and the current will be of the same magnitude, resulting in a great braking torque of the motor, which will stop the motor.

Q: I would like to ask, the inverter in use in the grid is very high?: In the process of using frequency converter, the demand for voltage fluctuation of power grid is not high. It depends on what brand of transducer. As a result, most of the grid voltage can meet the requirements, except in rural or remote areas where voltage changes exceed their permissible values. In addition, the frequency converter on the power grid harmonics also have requirements, if the harmonic content of more than 20%, will lead to frequency converter misoperation, false alarm, more serious circumstances, will lead to inverter out of control, or damage. However, most of the current harmonics will not happen, unless a large number of individual factories use frequency converters, servo, intermediate frequency furnace, welding machine and other equipment.

Q: Delta inverter fault output which parameter is set?: Parameter settings, class failures, frequency converter in use, whether it can meet the requirements of the transmission system, the parameter settings of the inverter is very important, if the parameter is not set correctly, it will cause the inverter not to work properly.

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.
