Mitsubishi electric introduced.
Since its establishment more than 90 years ago, mitsubishi electric Company has always insisted on developing and manufacturing the most reliable products and systems in a wide range of fields as an advanced environmental protection enterprise, from basic technology to the development of new products and even the research and development that will lead the development of new business in the future.
Mitsubishi electric has 32 manufacturing and sales enterprises in China, and has high-performance products which are beneficial to energy conservation and environmental protection in a wide range of fields, such as elevators, FA systems, air conditioners, power systems (transformers and motors), railway motor products, automotive electrical components, semiconductors and so on. China is also the largest market for mitsubishi electric's overseas business. Mitsubishi electric (China) Co., Ltd. established an investment and China regional integration company on 1997. The business philosophy is that "One mitsubishi electric" contributes to "a better future" and "a better society" in China. As the window of China, we will promote the "One mitsubishi electric" activity to enhance the comprehensive strength of mitsubishi electric Group!

How to tell the authenticity of mitsubishi electric?
The first is independent design, which can also be divided into two categories: partial independent design and completely independent design. The type of independent design of parts refers to the independent design of parts and the copy of parts. At present, the mainland has no ability to design and Mitsubishi's CPU, so CPU boards are designed independently by copying board, IO board and power board. So the method of judging this high copy machine is the same as judging the board type. However, the manufacturer of this product is more or less skilled and has a certain scale, but the quality control level is limited, so the quality is slightly better than that of the copy type, but there are also many problems.
The second type, completely independent design, is rare in Chinese mainland, but it is high-tech in Taiwan Province Province. Newly developed from top to bottom, it seems to be based on Mitsubishi FX2N series PLC. It is estimated that the original 1N/ 1S will be discontinued gradually, so Mitsubishi's latest 3G scheme is directly used. I guess the Japanese are starting to get scared when they think about it now. Judging from the appearance and internal technology of the whole product, it should still have a certain level, at least like the products of big companies, worthy of Mitsubishi. At present, I only see the relay module. What is even more shocking to me is that the Panasonic relay used is the same model as the real Mitsubishi PLC.

Mitsubishi electric price
Because of the different models, of course, the price will be different. Prices in mitsubishi electric range from several thousand dollars. I suggest you go to the physical store to inspect the goods before buying.
Mitsubishi electric fault
1.AL.24 Main circuit is abnormal.
Servo motor output (U V W phase) grounding fault.
Main reasons and treatment methods:
There is an open circuit in the power input and output wires of the main circuit terminal (TE 1). → Repair the wire.
The power cord surface of servo motor is damaged. → Replace the electric wire.
Servo amplifier main circuit failure. → Replace servo amplifier.
The braking current exceeds the allowable value of the built-in regenerative braking resistor or regenerative braking option.
2. Abnormal regenerative braking transistor
Content: The braking current exceeds the allowable value of the built-in regenerative braking resistor or regenerative braking option.
Main reasons and treatment methods:
The built-in regenerative braking resistor or regenerative braking option is not connected. → Correct wiring.
3. The power supply voltage is too low, lower than 160V.
Main reasons and treatment methods:
The supply voltage is too low. → Check the power supply system
Control the instantaneous power failure for more than 60 ms and check the power supply system.
Because the power supply capacity is too small, the power supply voltage drops at startup. → Check the power supply system
Turn off the power and then turn it on within 5 seconds. → Check the power supply system
Internal fault of servo amplifier. → Replace servo amplifier.
AL. 12 abnormal memory 1 → Replace servo amplifier.
AL. 13 clock is abnormal → replace servo amplifier.
AL. 14 Abnormal watchdog → Replace servo amplifier.
AL. 15 abnormal memory 2→ replace servo amplifier.
4.4. Abnormal coordination. AL. 1A motor.
Servo amplifier and servo motor do not match.
Main reasons and treatment methods:
Servo amplifier and servo motor are mismatched. → Use the correct fit.
The servo motor selected by parameter 0 does not match the servo amplifier currently used. → Set parameter 0 correctly.
5.AL.20 encoder is abnormal.
Communication between encoder and servo amplifier is abnormal.
Main reasons and treatment methods:
Incorrect connection of encoder connector CN2 → correct wiring.
Encoder cable failure (open circuit or short circuit → repair or replace cable.
Encoder failure → Replace servo motor.
Editor's summary: At present, the piracy in mitsubishi electric is still serious, especially in PLC, even to the point of confusing the real with the fake. Therefore, when we choose mitsubishi electric, it is necessary to have a pair of discerning eyes. If we buy from a regular manufacturer, don't always try to take advantage of others. We need a formal invoice when we buy it, and then we can better buy the real goods through some small details.
