Parameter Description
The data are based on the value registered by the kWh
counter in the adjustable frequency drive. This counter
value can be read in 15-02 kWh Counter containing the
accumulated value since the first power-up or latest reset
of the counter (15-06 Reset kWh Counter).
All data for the energy log are stored in counters which
can be read from 23-53 Energy Log.

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.
Counter with highest index will always be 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 Quick Menu, Loggings, Energy Log: Trending

NOTICE!
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
Days
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 a warning to be issued if the clock has not been
set properly, e.g., after a power-down.
