ABB is a globally recognized company in Europe and around the world, known for its expertise in high and low voltage electrical equipment, transformers, power generation systems, and other industrial applications. These products are mature and widely used across various sectors such as power plants, papermaking, and more. It can be said that ABB's products have gained widespread recognition and trust among users in China.
In the inverter market, ABB frequency converters stand out due to their stable performance, extensive expansion options, flexible programming environment, strong torque control, and a wide range of models designed for different applications. The market presence of ABB inverters in China is evident to all. With a strong brand reputation and high social recognition, ABB frequency converters hold a leading position in the Chinese inverter market.
Although ABB inverters have not been in the Chinese market for too long, they have gone through a process of initial unfamiliarity, gradual recognition, and eventual acceptance by customers. Their development has been very rapid. In the early days, ABB primarily introduced low-power ACS300 and standard ACS500 inverters. These two series did not attract a large customer base in China initially. However, it was the high-end ACS600 inverter, featuring DTC (Direct Torque Control) technology, that truly gained popularity among users. Known for its stability, reliability, rich features, and flexibility, the ACS600 became a key product that helped ABB gain a strong foothold in the market.
As the product line evolved, ABB launched the ACS800 as an alternative to the ACS600 drive. Compared to the ACS600, the ACS800 retains the DTC control mode and all original functions, but it also introduces a new feature: a built-in simple PLC function. This allows users to customize programs using 15 modules without needing special tools or programming languages. They can even draw the program on a function module template and store it directly. Additionally, the ACS600 and ACS800 offer a wide range of optional modules, including I/O expansion, PROFIBUS/Modbus communication interfaces, and industry-specific macro programs such as master-slave macros for papermaking machinery, swing frequency macros for textile machines, PFC macros for constant pressure water supply, PID control macros, and torque control macros. These options make ABB inverters highly adaptable to various industrial needs.
For different customer segments, ABB has introduced the ACS550, a mid-range inverter with excellent cost-performance, as well as the low-end ACS400 and low-power models like the ACS100 and ACS140. These products cater to a broad range of applications and user requirements.
Despite ABB's strong market presence in China, many older models such as the ACS200, ACS300, and ACS500 are now experiencing frequent failures due to prolonged use. As a result, there are numerous common issues that users often encounter. Below, we will discuss some typical faults found in ABB inverters and provide practical solutions to help users address them effectively.
