The SERCOS vendor organizations have developed an energy conservation profile for the SERCOS III Real-time Ethernet Communications System. This profile reduces energy consumption in three areas: the permanent load at motor/machine standstill; energy consumption during partial load operation; and energy consumption of components not required at a particular time or point in the process (partial machine operation).
This application layer profile defines parameters to reduce energy consumption in a uniform and vendor-independent manner. The control reads out standard parameters of each component through the SERCOS III network, receiving status information and detailed consumption values. Depending on the situation the control can switch connected components (drives, I/O, sensors) into energy-saving conditions, up to complete shut down, in a targeted manner, considerably reducing their energy consumption.
