- 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., the 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 the time
frame and a split on hours, days or weeks.
The period/split (resolution) can be set in par.23-50
Energy Log Resolution.
The data are based on the value registered by the kWh counter in the adjustable frequency drive. This counter
value can be read in par.15-02
kWh Counter containing the accumulated value since the first power-up or latest
reset of the counter (par.15-06
Reset kWh Counter).
All data for the energy log are stored in counters which can be read from par.23-53
Energy Log.
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.
The counter with the highest index will always be subject to updates (containing data for the current hour since
XX:00 or the current day since 00:00).
The contents of counters can be displayed as bars on keypad. Select
