Appendix B – CoE error codes
What this chapter contains
This chapter contains a list of the CANopen over EtherCAT error 
codes.
Error codes
Error codes can be read from object 0x603F Error code. The CoE 
error codes are described in the following table. Error codes 
between xx80…xxFF (hex) and FF00…FFFF (hex) are 
manufacturer-specific. Descriptions for these error codes can be 
found in the appropriate drive firmware manual and/or the drive 
fault code parameter. Furthermore, the following two error codes 
are generated by the adapter module:
• 0xFFE1: Failed to read the fault code from the drive.
• 0xFFFF: Unhandled drive fault code (corresponding CiA 402 
error code does not exist. See object 0x2201 for the original 
drive fault code and consult the drive manual).
