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 Commissioning/reset
0.5 Hz
Flashing light 2 Writing to the memory card.
Hz
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 activated
2 Hz (see SINAMICS S120/S150 List Manual).
Note:
Both possibilities depend on the status of the LED
when activating.
OFF Cyclic communication is not (yet) running.
Note:
The PROFIdrive is ready for communication when
the Control Unit is ready for operation (see LED:
RDY).
Continuous light Cyclic communication is taking place.
Flashing light Cyclic communication is not fully established yet.
0.5 Hz Possible causes:
- The controller is not transmitting any setpoints.
- In isochronous mode, the controller is not sending
a GC (Global Control) or is sending a defective
GC.
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 or
2 Hz could not be established.
