This object is used to latch the latest failure and its properties.
Error code is latched by the bottom two bytes. For details, refer to the error code list.
"Additional information" is latched by the top two bytes. The top bytes of additional information (1002h, bits 16 to 23) are set up with the same information as the bottom bytes (1001h).
The latch error number is stored in sub index 0.

When a new error occurs, the displayed code moves to the sub index at the upper level. That is, error of sub index 1 goes to sub index 2, and error of sub index 2 goes to sub index 3. Afterward it is processed similarly. A maximum of 254 errors are stored.
History of error codes can be deleted by writing value 0 to sub index 0 of the object 1003h. The error codes are not deleted from PEF even if the error is fixed.
All failures are notified by sending EMCY message ("emergency" message). When the error conditions are removed, a no-error EMCY message is sent (error code 0x0000).
