If [Number of Files to Save] is set to 0, the
files are saved until the [CF Card] or [USB Storage] capacity is
reached.
Until the number of error log files reach the
number set in the [Number of Stored Items], records are added to
the latest error log file.
However, if you change the date or time, an error log file may be
created with the wrong date or time. In this case, with the new
date, records are not added even if the system has not reached the
[Number of Stored Items].
When the number of error messages exceeds
[Number of Files to Save] in [Error Settings], the oldest file is
deleted to add a new file.
