CE04 MCI Communication error

Question:
What causes can a CE04 MCI communication error have?
 
Answer:
If MCI is set as source for synchronization in C1120/0 [4], the synchronization signal is expected at a specified time.
The code position C01123/0 defines a time window around the synchronization time in which the sync signal must arrive.
This time window must be set to 100µs. A different setting can lead to CE04 error messages.
 
Further possible causes are:
- EMC faults
- Communication module not inserted correctly
- Defect of the communication module or the drive controller
