3. Parameter Description
3.21.3. Energy Log, 23-5*
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 par. 23-50,
The data are based on the value registered by the kWh counter in the frequency converter. This counter value can be read in par. 15-02,
containing the accumulated value since the first power up or latest reset of the counter (par. 15-06,
All data for the Energy Log are stored in counters which can be read from par. 23-53,
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. Select
