NOTE!
The Adjustable frequency drive has no backup of the clock
function and the set date/time will reset to default
(2000-01-01 00:00) after a power-down unless a Real Time
Clock module with backup is installed. Consequently the
logging will be stopped until date/time is readjusted in
0-70 Date and Time. In 0-79 Clock Fault it is possible to
program for a warning in case the clock has not been set
properly, e.g., after a power-down.
