Announcement of New Frequency Converters from Rockwell Automation
At its annual automation fair in the USA, Rockwell Automation presented a new family of modular frequency converters. They utilize an innovative field-oriented control technology called TotalForce, which provides efficient motor management. This technology allows for precise and adaptive control of speed, torque, and position.
The system includes several patented features designed to optimize system operation and enhance performance. The TotalForce technology is implemented in the new Allen-Bradley PowerFlex 755T drives, which include models that suppress the influence of harmonics. As noted by Rockwell's product manager, Brad Arentz, "the new drives are designed to save installation costs, ensure efficient operation and maintenance, while providing enhanced capabilities that will optimize the use of your resources."
Features of the New Drives
It is important to highlight the drives that have high power and cover a working range from 160 kW to 24 MW at voltages of 400-690V. They are equipped with predictive diagnostics functions that assess the reliability of components such as fans, relay contacts, power semiconductor components, and capacitors. Additionally, the drives are certified to the international standard IEEE 519.
Ease of Installation and Maintenance
The converter modules can be easily completely removed from the chassis, creating space for wiring. Power remains connected during the module removal. Installation and maintenance are simplified thanks to auxiliary trolleys that allow one person to insert or remove any modules without the use of ramps or hoists.
Software for Drive Configuration
The drives can be configured using Rockwell Software's Studio 5000, which is also used for programming Rockwell Logix controllers, saving time on programming and simplifying the commissioning and diagnostic optimization process.
