Meaning of the LEDs on the S120 Combi

The SINAMICS S120 Combi has two LEDs to display the status of the components. The
software assigns a priority to the status signals from the individual components. The most
important and/or most informative status is output for the complete S120 Combi.
The status is immediately output if any component develops a fault. The ready to run
indication is only issued if all of the components have signaled that they are ready to run.
The LED statuses for the S120 Combi are described in the table below. The status display
always refers to the complete S120 Combi.
