Error log index

Indicates the latest error log number. If an error has not occurred, 00 is displayed.

Error log 1 to 5

When an error occurs, the error log index value is incremented and information at the time the error occurred is recorded in the error log area specified by this value. When the error log index exceeds 05, it returns to 01.

Command data 1 to 5

Indicates five commands data in order received by the device until the error occurs. Commands for which an error occurred are included in Command Data 5.

Error data

Indicates the I/O register values when the error is reported.
