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.
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 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
e.g. last 7 days within the pre-programmed
period
For each of the above 2 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
parameter 23-50 Energy Log Resolution.
The data are based on the value registered by the kWh
counter in the frequency converter. This counter value can
be read in parameter 15-02 kWh Counter containing the
166
Function:
Set this parameter to [1] Do reset to reset the
Maintenance Word in parameter 16-96 Maintenance
Word and reset the message displayed in the LCP.
This parameter changes back to [0] Do not reset
when pressing [OK].
Function:
6 individual texts (Maintenance Text
0...Maintenance Text 5) can be written for use in
either parameter 23-10 Maintenance Item or
parameter 23-11 Maintenance Action.
The text is written according to the guidelines in
parameter 0-37 Display Text 1.

All data for the energy log are stored in counters which
can be read from parameter 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.
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 LCP.

Option:
[0] Hour of Day

(P 15-02, kWh Counter)
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 (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
parameter 23-51 Period Start, and continues
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 5 weeks back in time and up to the
actual time.
The logging starts at the date programmed in
parameter 23-51 Period Start. In all cases the
period split refers to Operating Hours (time
where frequency converter is powered up).
