Counter 00 always contains the oldest data. A counter
covers a period from XX:00 to XX:59 if hours or 00:00 to
23:59 if days.
If logging either the last hours or last days, the counters
shift contents at XX:00 every hour or at 00:00 every day.
The counter with highest index is always subject to update
(containing data for the actual hour since XX:00 or the
actual day since 00:00).
The contents of counters can be displayed as bars on the
LCP. Select

NOTICE
The frequency converter has no back-
up of the clock function and the set
date/time resets 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 is
stopped until date/time is readjusted
in
parameter 0-70 Date and Time . In
parameter 0-79 Clock Fault it is possible
to programme a warning if the clock
not has been set properly, for example
after a power-down.
Select the desired type of period for logging
of consumption.
[0] Hour of Day , [1] Day of

parameter 23-51 Period Start ) and the
numbers of hours/days as programmed for
(
parameter 23-50 Energy Log Resolution ).
The logging starts on the date programmed
in
