Hi,
set the compiler define in the application properties:

CANOPEN_DEBUG

then download the project and check the plc logger for more details on These Problems on the CAN communication.

Thank you !

The servo error code is AL3E2 or AL3E3.

AL3E2: CANopen SYNC signal error
The CANopen SYNC signal is received too early.

AL3E3: CANopen SYNC timeout
The CANopen SYNC signal is not received within the specified time.

When I use LMC058 of Schneider in Somachine , the SYNC way is different.
They use the External signal. Can pi use this way?

Hi,
from your screenshots your realtime should be good enough (maybe I'm wrong) but I would give this a try
to generate the sync on the Raspberry PI
