Detection of the component via LED is activated
(p0124[0]).
Note:
Both options depend on the LED state when
activating via p0124[0] = 1.
-
- 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. -
Green
Flashing light
0.5 Hz
Cyclic communication is not fully established yet.
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
0.5 Hz
The PROFIBUS master is sending a faulty
parameter assignment or the configuration file is
corrupted.
Modify the configu-
ration between master

Red
Flashing light
2 Hz
Cyclic bus communication has been interrupted
or could not be established.
Rectify the bus
communication fault.
MOD - Off - -
- Off - - OUT > 5 V
Orange Continuous light The voltage of the electronic power supply for
the measuring system is 24 V.

1) Make sure that the connected encoder is designed for a 24 V supply. Connecting a 5 V encoder to a 24 V supply can
result in destruction of the encoder electronics.
