Abstract: This paper takes the Swiss WIFAG 370 offset rotary press as an example to briefly introduce the application of AMK frequency converter in printing machinery. Keywords : AMK inverter, WIFAG 370 , No shaft drive, Plate cylinder, Rubber roller 1 Introduction With the development of electronic technology, AC motor frequency conversion speed regulation technology has been widely used in various industrial productions. As a pioneer in the field of electric drive control, the German company AMK was the first manufacturer to develop digital frequency conversion drive technology. Its frequency converters are widely used in various advanced imported control systems due to their stable and reliable performance. This paper mainly combines the characteristics of printing machinery, taking the imported Swiss WIFAG 370 rotary press as an example to briefly introduce the typical application of AMK frequency converters in printing machinery. [b]2 Characteristics of Printing Machinery (1) Good Stability[/b] Newspaper printing has extremely high time requirements, therefore printing equipment must be able to operate stably and reliably for a long time. (2) Easy Maintenance The time-sensitive nature of newspapers means that equipment malfunctions must be resolved in a short time, therefore equipment must be easy to maintain and repair. (3) Good Safety Performance Printing machinery has high speed and is large, requiring good safety performance.
