Series AC converters PowerFlex 755 from the company Rockwell Automation (Allen-Bradley) They represent a universal solution for a variety of industrial applications, a favorable price, a rich arsenal of functions and tools for efficient operation and ease of interaction. Three types of control methods have been implemented for asynchronous motors and two for synchronous permanent magnet electric motors in a wide power range (from 0.37 to 1500 kW). The speed setting is carried out with and without feedback sensors, fine-tuning the moment and performing positioning tasks.
The model range is presented in ten dimensions, there is a wall and floor type of installation, an open and closed housing version, flanged mounting. Four voltage ratings are available to supply the drive in the low-voltage range (200 - 690 V). Overload capacity implies three operating modes (light, normal and heavy).
The PowerFlex 755 functionality allows you to receive real-time diagnostic data, the EtherNet/IP port is used by default for network communication, and various types of adapters can also be installed to support popular industrial protocols. The built-in logic controller makes it possible to automatically configure the parameters. The included software products are powerful tools for debugging the operation of the drive, they provide fast, simple hardware integration and maximum system performance.
