CAN-IN1 Event/Time Communication Error
Lenze · 8200 Series
What does ce3 mean?
A communication error has occurred on CAN-IN1 during event or time-controlled operation, indicating faulty data or interrupted communication. This can stem from loose bus module connections or issues with the transmitting device. Loss of critical event or time-based communication can disrupt synchronized operations.
Common Causes
- Intermittent connection or loose seating of the CAN-IN1 communication module.
- Corrupted data packets on the CAN-IN1 bus due to signal integrity issues (e.g., reflections, noise).
- Timing discrepancies or delays in message transmission or reception for event/time-critical data on CAN-IN1.
- Incorrectly configured transmit or receive parameters for specific CAN-IN1 telegrams (e.g., P8-05, P8-06).
- Sporadic high bus load or device malfunction causing dropped or delayed time-sensitive messages.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Inspect the CAN-IN1 communication module and connector for any signs of intermittent contact or damage.
- 2
Check the CAN-IN1 bus cabling for any intermittent shorts or open circuits by gently flexing the cable while monitoring communication status.
- 3
Verify that the configured baud rate (P8-01) for CAN-IN1 matches all devices and is sufficient for the real-time event/time-controlled data exchange.
- 4
Review specific CAN-IN1 event/time control parameters (e.g., P8-05 for telegram type, P8-06 for timeout) and ensure they are appropriately configured for the application.
- 5
Temporarily disconnect non-essential devices from the CAN-IN1 bus to isolate the source of high bus load or interference.
