How to learn the knowledge of the inverter? For many people who have just contacted the inverter, how to learn is a crucial issue. In order to learn the knowledge of the inverter, in addition to a certain foundation, there must be practical operation after theoretical study. Learn the problems that the frequency converter should pay attention to, and hope to make some reference for the novice.

First of all, the teacher of the inverter training suggested: the combination of theory + practice

Theory: Understand the meaning of each parameter of the inverter, the principle of the inverter, the control method, the approximate operation of the manual, know what is going on

Practice: Combine some special requirements of practice to debug, this requires the accumulation of experience

Secondly, you can also go to some inverters and plc training institutions to improve yourself and improve your skills by participating in training. This is a way to learn quickly.

If you are doing repairs or after-sales, you must know the main circuit diagram, rectification, filtering, and inverter of the inverter. Some electronic components must be known, such as varistor, charging resistor, voltage equalizing resistor, non-inductive capacitor, filter capacitor, and various optocouplers of the driver circuit such as 250, 350, 3120, 316. This is the abbreviation, the role and pin of these optocouplers must be known. Because the process of maintenance is always necessary to judge the quality of the device.

After the sale, we must understand the working characteristics of the motor. It is recommended to learn some macroscopic things, that is, the motor. You know, otherwise, the on-site motor is broken, which will definitely cause the inverter to not work properly. Such as the rated current of the motor, the insulation winding of the motor. There is also a commonly used low-voltage electrical appliance, which mainly uses switch box contactors, relays, tachometers, and potentiometers (used during installation). This is just the most basic thing you can do very quickly. If you want to learn well, learn these courses (power electronics) (number, module operation part) (circuit, mainly the op amp section) (low-voltage electrical) (motor and drag) have the energy to learn the PLC.

The learning of the inverter should pay attention to the operation. Only by applying the learned to the actual project can it be improved. Look at the books of the inverter, learn more about the inverter related information, and practice the inverter project, so that you can learn the inverter.
