Table 10- 10 Description of the Sync and Fault LEDs on the CBE20
Fault --- OFF If the link port LED is green:
The CBE20 is operating normally, data is being exchanged with the con-
Red Flashing light - The response monitoring time has elapsed.
- Communication has been interrupted.
- The IP address is incorrect.
- Incorrect or missing configuration.
- Incorrect parameter assignment.
- Incorrect or missing device name.
- IO controller not present/switched off but Ethernet connection present.
Continuous light CBE20 bus fault
- No physical connection to a subnet/switch.
- Incorrect transmission rate.
- Full-duplex transmission not activated.
Sync --- OFF If the link port LED is green:
Control Unit task system is not synchronized with the IRT clock. An inter-
nal substitute clock is generated.
Green Flashing light
Control Unit task system has synchronized with the IRT clock and data is
being exchanged.
Task system and MC-PLL have synchronized with the IRT clock.
Table 10- 11 Description of the OPT LED on the Control Unit
OPT --- OFF Electronics power supply is missing or outside permissible tolerance
range.
The CBE20 is defective or not inserted.
Green
CBE20 is ready and cyclic communication is taking place.
0.5 Hz flashing
light
CBE20 is ready but cyclic communication is not running.
Possible causes:
- Communication is being established.
-At least one fault is present.
Red Continuous light Cyclic communication via PROFINET has not yet been established.
However, acyclic communication is possible. SINAMICS is waiting for a
parameterization/configuration telegram.
0.5 Hz flashing
light
The firmware download to the CBE20 has failed.
Possible causes:
- The memory card of the Control Unit is faulty.
- The CBE20 is out of order.
The CBE20 cannot be used in this state.
2 Hz flashing
light
Communication between the Control Unit and the CBE20 is faulty.
Possible causes:
- The CBE20 was removed following power-up.
- The CBE20 is defective.
Orange 0.5 Hz flashing
Firmware is being updated.
