Upgrading of control systems for main drives of foil mill.
The company specialists have finished the activities on upgrading of control systems for main drives of foil mill C2 «FATA HUNTER». Sinamics DCM CM modules were mounted on mill drive for control of existing thyristor converters «ANSALDO», while packaged converters Sinamics DCM were mounted on decoiler and coiler drives. Mill central control was implemented with central processor S7-416-2DP instead of Simatic S5 that was previously used. Increased data exchange speed and adjusted counting units enabled significant improvement of ribbon thickness control and ensured steady strip tension keeping.
