State Description / cause
Off Electronics power supply is missing or outside
permissible tolerance range.
Continuous light The unit is ready for operation.
Cyclic DRIVE-CLiQ communication is in progress.
Flashing light 0.5 Commissioning/reset
Hz
Flashing light 2 Hz Writing to the memory card.
Flashing light General error
2 Hz
Flashing light The Control Unit is ready for operation, but there
0.5 Hz are no software licenses.
Flashing light Updating the firmware of the DRIVE-CLiQ com‐
0.5 Hz ponents.
Flashing light DRIVE-CLiQ component firmware update com‐
2 Hz pleted. Waiting for POWER ON of the correspond‐
ing component.
Flashing light Recognition of the component via LED is activa‐
2 Hz ted (see SINAMICS S120/S150 List Manual.)
Note:
Both options depend on the LED status when
component recognition is activated.
Off Cyclic communication has not (yet) taken place.
Note:
PROFIdrive is ready for communication when the
Control Unit is ready (see LED: RDY).
Continuous light Cyclic communication is taking place.
Flashing light Full cyclic communication is not yet taking place.
0.5 Hz
Possible causes:
● The controller is not transferring any setpoints.
● During isochronous operation, no GC (Global
Control) or a faulty GC is transferred by the
controller.
Flashing light The PROFIBUS master is sending a faulty param‐
0.5 Hz eter assignment or the configuration file is corrup‐
ted.
Flashing light Cyclic bus communication has been interrupted
2 Hz or could not be established.
