Upgrade of control system for laminating machine.
The company specialists have completed commissioning works to upgrade a control system for laminating machine E-2 at JSC RUSAL SAYANAL in the town of Sayanogorsk, as part of the project on implementation of the same-name project, developed by JSC ASC.
8 thyristors of a main electric drive of the machine were replaced with Sinamics DCM converters, and new incremental speed transducers were installed instead of the existing tachometric generators. A speed synchronizing system for the machine’s transport mechanisms was implemented within the automaton system, based on Siemens S7-1500 controller (earlier it was implemented using analog control boards). Control of the machine’s auxiliary mechanisms was implemented too. The main control panel was replaced with a new operator panel TP1900.
As a result of this upgrade, the management and trouble-shooting of the machine has been simplified. The use of a more reliable and up-to-date equipment has significantly contributed to reducing the equipment downtimes.
