3.20.3 23-5* Energy Log
The frequency converter is continuously accumulating the
consumption of the motor controlled, based on the actual
power yielded by the frequency converter.
This data can be used for an energy log function allowing
to compare and structure the information about the
energy consumption related to time.
There are 2 functions:
•
Data related to a pre-programmed period,
defined by a set date and time for start.
•
Data related to a predefined period back in time,
for example last 7 days within the pre-
programmed period.
For each of the above 2 functions, the data is stored in
several counters allowing for selecting time frame and a
split on hours, days, or weeks.
The period/split (resolution) can be set in
parameter 23-50 Energy Log Resolution
.
The data is based on the value registered by the kWh
counter in the frequency converter. This counter value can
be read in
containing the
accumulated value since the first power-up or latest reset
of the counter (
parameter 15-06 Reset kWh Counter
).
All data for the energy log is stored in counters, which can
be read from

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 shown as bars on the LCP.

NOTICE
The frequency converter has no back-
up of the clock function. 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. Therefore, the logging is
stopped until date/time is readjusted
in
parameter 0-70 Date and Time
. In
, it is
possible to program a warning if the
clock has not been set properly, for
example after a power-down.
