Migración de MOVIMOT a variadores de frecuencia DANFOSS e integración al controlador SIEMENS del proceso de paletizado

Abstract

The present research aims to carry out the migration of six integrated MOVIMOT drive units to Danfoss VLT FC 280 variable frequency drives, integrated into a Siemens S7-300 controller through the PROFIBUS-DP network. The project is developed under the hypothesis that centralized control architecture increases operational reliability and reduces maintenance costs associated with failures caused by thermal fatigue and mechanical vibrations present in decentralized systems. The justification is based on the need to improve the maintainability of the palletizing system and ensure its operational continuity in an industrial environment. The project development was carried out through the design of a new centralized control panel and the reengineering of the PLC program using SIMATIC Manager software. Danfoss FC 280 variable frequency drives were used, with PROFIBUS-DP communication implemented via GSD files, and the MCT 10 tool was employed for drive parameterization. The electrical design and protective devices were defined in accordance with regulatory criteria established by IEC 60364-4-43. The results obtained demonstrated stable and deterministic communication between the PLC and the variable frequency drives, enabling precise control of speed, acceleration ramps, and operational states. Functional tests confirmed that the migrated system replicated the original sequential logic of the palletizing process without affecting its performance. The research concludes that the centralized architecture improves system maintainability, reduces maintenance intervention times, and provides greater flexibility for future process expansions.
