23-50 Energy Log Resolution
Option: Function:
Select the desired type of period for logging
of
consumption. [0] Hour of Day, [1] Day of
Week or [2] Day of Month. The counters
contain the logging data from the
programmed date/time for start (23-51 Period
Start) and the numbers of hours/days as
programmed for (23-50 Energy Log Resolution).
The logging will start on the date
programmed in 23-51 Period Start, and
continue until one day/week/month has gone.
[5] Last 24 Hours, [6] Last 7 Days or [7] Last 5
Weeks. The counters contain data for one day,
one week or five weeks back in time and up
to the actual time.
The logging will start at the date programmed
in 23-51 Period Start. In all cases the period
split will refer to Operating Hours (time where
frequency converter is powered up).

NOTE
The frequency converter has no back up 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 back up is installed. Consequently, the
logging will be stopped until date/time is readjusted in
0-70 Set Date and Time. In 0-79 Clock Fault it is possible to
program for a Warning in case clock not has been set
properly, e.g. after a power down.

Data from latest period is stored in the
counter
with the highest index.
At power down all counter values are stored
and resumed at next power up.
NOTE
All
counters are automatically reset when changing the
setting in 23-50 Energy Log Resolution. At overflow, the
update of the counters will stop at maximum value.
NOTE
When
mounting an Analog I/O MCB 109 option card, a
