Cause Description Measure Acknowledgement
1:CAN LifeGuard The device detects the Life-Guarding
event (master no longer sends any
Remote Transmit Request).
Check the CANOpen master. Switch off/on the Esc key of
the device at the front of the in-
verter or rising flank of the en-
able signal or programmed
acknowledgement
2:CAN Sync Error Sync message was not received
within the timeout period that is cal-
culated from the A201 Cycle Period
Timeout as follows:
• A201≤20 ms:
Timeout period = A201 * 4,
•20 ms < A201≤ 200 ms:
Timeout period = A201 * 3,
• else: Timeout period = A201 * 2
• Make sure that the A201 param-
eter is correctly set.
• Make sure that the master sends
the sync message reliably.
Switch off/on the Esc key of
the device at the front of the in-
verter or rising flank of the en-

repeated CAN bit timing errors. The
CAN controller is restarted after a
waiting time of 2 s and acknowledge-
ment of the malfunction.
• Make sure that the CAN baud
rate was correctly set.
• Check the wiring
• Check the bit timing of a different
CAN subscriber.
