3.21.3 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.
These data can be used for an Energy Log function allowing
the user to compare and structure the information about the
energy consumption related to time.
There are basically two 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
e.g. last seven days within the pre-programmed
period
For each of the above two functions, the data are stored in a
number of counters allowing for selecting time frame and a
split on hours, days or weeks.
The period/split (resolution) can be set in
.
The data are 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
(
).
All data for the Energy Log are stored in counters which can
be read from

Counter 00 will always contain the oldest data. A counter will
cover 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 will
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 LCP.

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