The adjustable frequency drive is continuously accumulating the consumption of the motor controlled, based on the actual power yielded by the adjustable
frequency drive.
These data can be used for an Energy Log function allowing the user to compare and structure the information about the energy consumption related

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., 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
