While operationally obsolete, the 15-plus-year old cycloconverter in the hot strip mill still had significant life remaining. Nidec improved its long-term performance with a state-of-the-art ARTICS control system.
Nidec’s services included system and installation engineering, system erection, commissioning the Automation PLC Porting and training staff on the system’s operation. The completed system today provides stable and reliable performance, while working near the cycloconverter’s maximum admissible frequency – 20.66 Hz.
The new ARTICs control system offers multiple advantages over the older analog system.
