NOTICE
Damage to components
If CAN cables are connected to the X126 interface, the CU320 or other CAN bus nodes can
be damaged.
Do not connect any CAN cables to the X126 interface.
Note
A teleservice adapter can be connected to the PROFIBUS interface X126 for remote
diagnostics purposes.
The power supply for the teleservice (terminals 2 and 7) can have a load of up to 150 mA.

Color Status Description
----- Off Cyclic communication has not (yet) taken place.
Note:
If the Control Unit is operational, the PROFIdrive is ready for communication. The DP1
LED illuminates.
Green Continuous light PROFIBUS is ready for communication and cyclic communication is taking place.
Green 0.5 Hz flashing light Full cyclic communication is not yet taking place.
● The controller is not transferring any setpoints.
During isochronous operation, no or a faulty global control (GC) is transferred by the
controller.
Red Continuous light Cyclic communication has been interrupted.
