State Description / cause
OFF The electronics power supply is missing or
outside the 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 fault
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
0.5 Hz components.
Flashing light DRIVE-CLiQ component firmware update
2 Hz completed. Waiting for POWER ON of the
corresponding components.
Flashing light Recognition of the component via LED is
2 Hz activated (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
0.5 Hz parameter assignment or the configuration file is
corrupted.
Flashing light Cyclic bus communication has been interrupted
2 Hz or could not be established.
