Sappi Alfeld: Modernization sheeter
Sappi Alfeld: Modernization sheeter
To ensure future spare parts availability and technical support, the decision was made to modernize the sheeter with regards to control- and drive technique. The S5 control was replaced by new S7 400 controls and hardware interfaces were combined in one software project. The new operating philosophy via PC with touchscreen was adapted to the original operating concept as much as possible. Also the existing DC drive controllers were replaced by modern Sinamics DC-Masters and the suction slide valve was equipped with a new servomotor.
