We are using Codesys v3.5 SP15 with EtherCAT Master Soft Motion.
When we configure the Distributed clock to SM-Syncrhon, all it is Ok.
But when we configure to DC-Syncrhon, we get error. The SM_DRIVE_GenericDSP402 indicate FB Error: SMC_ERROR.SMC_DI_GENERAL_COMMUNICATION_ERROR
The status xDistributedClockInSync is False
The error in the status field of the SM_Drive_ETC_GenericDSP402 says "Configuration Error" when the problem occurs.
But our drive using the Beckoff SSC stack indicate all status to syncrhonized.
When I parse the forum, I try by add EtherCAT_Master_SoftMostion.FramAtTaskStart = FALSE.
By this, I get communication fex second (1 or 2s maximum), then I get another error: SMC_DI_FIELDBUS_LOST_SYNCRONICITY
Is there any documentation about error signification and the way to resolve them?
Our Drive all work properly using Beckoff TwinCAT in SM and DC Synchron.
The PLC task is configured to 2ms, the Cycle execution time is about 200 to 300µs.
Please, could have some idea to investiguate our problem?
