))
The number of errors occurred is stored.
0: No error
1 to 65535: Number of errors occurred
1 to 65535: Number of errors occurred
Even if errors occurred 65536 times or more, the count will stop at 65535.
Error log number of the latest error is stored.
0: No error (No error log)
1 to 64: Error log number of the latest error
1 to 64: Error log number of the latest error
If the 65th or more error occurs, it will return to error log No.1 and start registration again.
