Electroglobal SA<\/strong> implemented this project as requested through a construction materials company.<\/p>\n

Project Objective<\/strong><\/h6>\n

The purpose of this project was to replace an outdated drive system with a Siemens Sinamics G130 converter system, including protection & switching and automation systems, to meet higher process demands while preventing overload.<\/p>\n

The automation system efficiently and automatically manages three converters that control two motors. Two of the converters operate in parallel to power the motors, while the third remains in standby. In the event of a failure or maintenance operation on one of the main converters, the standby converter activates to ensure continuous motor operation.<\/p>\n

The system is designed so that switching between converters is only possible in Local mode via the HMI interface and only when all VFDs are stopped, as per a software interlock. Additionally, the system retains the last used configuration, ensuring that settings are automatically restored upon power restoration.<\/p>\n

Project Description<\/strong><\/h6>\n

The automation system utilizes a set of switches and disconnectors that allow any two converters to operate the two motors, ensuring their power supply from a transformer with a 6kV primary and two 0.4kV secondaries. The selection of converters is only possible if disconnectors C1-C8 are in the correct configuration, as specified in the project\u2019s reference table.<\/p>\n

The frequency converters are interfaced with the HMI system (TP1200 Comfort model) via a Siemens S7-1200 programmable logic controller (PLC), model CPU 1214C DC\/DC\/RLY. This PLC is responsible for monitoring the converters’ parameters and implementing the control logic necessary to ensure the system operates under optimal conditions.<\/p>\n
