Advantages of choosing a frequency converter

What happens when the inverter-controlled motor presses the abort button, and the motor is not controlled to speed up? 1. If it is a newly installed inverter, it is generally necessary to consider the wiring problem, you can first change the parameters to switch to the panel control, the panel is given the frequency, and then see if the inverter operation will appear in this ...

There are many special faults, which come and go, looming, making it impossible to judge and deal with. At this time, you can clean the circuit board with water or alcohol, and brush off the dust and rust on the circuit board with a soft brush, especially pay attention to the solder joints are dense, and the circuit near the 0 volt copper layer is also ...

In general, the long-distance operation of the frequency converter requires the following functions: 1) Long-distance setting, if the parameters only need to be set for the first time, and do not need to be adjusted during operation, then long-distance setting is not required. 2) Long-distance start-stop, long-distance start or stop inverter, and ...

The supplier of the supporting equipment of the inverter reminds you that the voltage waveform output by the inverter is similar to a sine wave, but not a real sine wave. Its waveform contains a large number of harmonic components, especially the higher harmonics will increase the output current of the inverter, causing the motor winding to heat up, and produce oscillation.

1. The wires of the inverter control circuit should be strictly distinguished from the main circuit cable (power line) and placed separately. This will help prevent the inverter's control circuit from being disturbed by harmonics in the inverter's main circuit. 2. To separate the connection of the inverter from the terminals or contacts of other control circuits, ...

Robot contactors are noisy? Cause: It is likely that the joint contact surface of the contactor is uneven, and the surface is sand or rust. The result will constitute a phase loss, which will lead to the burnout of contactors, switch frequency conversion and other components. Solution: will control the ...

Assuming that the inverter has a built-in braking unit and additional braking resistors, it is important to pay attention to the correct wiring of the braking resistors. The braking resistor should be connected between the P terminal and the DB terminal, but not between the P terminal and the N terminal, otherwise the three-phase rectifier bridge will operate at full load when it is not working, resulting in the equipment being unable to ...

How to choose the speed control form of the general inverter: the general inverter is also known as the high-performance inverter, the PG-free vector inverter, and the torque control inverter, why? Originally, the main speed control form is different, so how to choose the speed control form of the inverter? ...

In the process of repairing the switching power supply, the step-down method can be selected. The method is: by connecting the power plug of the display to a communication voltage regulator, and then adjusting the output voltage of the voltage regulator to about 100V, and then repairing it with electricity, and gradually improving the power supply voltage for repair. ...

1. Select the inverter according to the load characteristics, such as the load is constant torque load, you can choose Siemens MM440 inverter, ABB ACS800 series inverter, etc.; If the load is a fan or pump load, you can choose Siemens MM430 inverter, ABB ACS510 series inverter, etc. 2、 ...

If there is no damage to the hardware, the maximum torque output of the inverter is generally less than the load to increase the torque. The acceleration time is too short ...

In the process of operation, try to ensure that the inverter (hereinafter referred to as -VFD) has a satisfactory acceleration and deceleration time, and the VFD has its own soft start function when starting or accelerating; When the power is shut down or the speed is slowed down, it has the function of soft shutdown. Add acceleration and deceleration times as much as possible within the range promised by the device. When the device requires ...

1. The capacitance is generally indicated by "C" plus a number in the circuit (e.g., C25 indicates the capacitance numbered 25). A capacitor is a component consisting of two metal films close to each other and separated by an insulating material in the center. The characteristic of the capacitor is mainly to communicate through the DC block. The size of the capacitance is ...

Natural heat dissipation methods are generally used for heat dissipation of small-capacity inverters, because their operating environment should be well ventilated and free of dust and floating objects. The dragging objects of this type of inverter are mostly household air conditioners, CNC machine tools, etc., and the power is small. ​ ...

1. Control method: i.e. speed control, rotation control, PID control, or other methods. After the control method is adopted, it is generally necessary to carry out static or dynamic identification according to the control accuracy. 2. Minimum operating frequency: That is, the minimum speed of the motor operation, the motor at low speed ...

1. The "FUNC/DATA" key is a programming key, press this button once to convert the operation mode, and press it again to read and write the function code; 2. The "SET/>>" button is the display switch and shift key, press this key to switch the display content, and press it again to ...

Natural heat dissipation methods are generally used for heat dissipation of small-capacity inverters, because their operating environment should be well ventilated and free of dust and floating objects. The drag targets of such inverters are mostly household air conditioners, CNC machine tools, etc., and the power is small. Still...

1. Cooling fan As a prerequisite for ensuring the normal operation of the inverter, efficient and fast in-line cooling fans have become an indispensable conversion configuration of the inverter. Because of the wear of the internal bearings of the cooling fan and the reduction of the grease function in the process of application, the cooling of the fan.

The wearing parts of the driver mainly include electrolytic capacitors for filtering and cooling fans, and their service life is closely related to the environment and maintenance of the operation. Depending on the operating moment, the user can determine whether a wear part needs to be replaced. Cooling ...

1. What is frequency conversion resolution? What's the point? In the case of digitally operated inverters, the output frequency is given in a given order, even if the frequency command is an analog signal. The smallest unit of this gradient is called the variable resolution. Change...
