￭ Energy saving calculators
This feature consists of the following functionalities:
• An energy optimizer that adjusts the motor flux in such a way that the total system
efficiency is maximized
• A counter that monitors used and saved energy by the motor and displays them in
kWh, currency or volume of CO
2
emissions, and
• A load analyzer showing the load profile of the drive (see separate section on page
100.
Note: The accuracy of the energy savings calculation is directly dependent on the
accuracy of the reference motor power given in parameter 45.19.
Settings and diagnostics
Parameter group: 45 Energy efficiency (page 400).
￭ Load analyzer
Peak value logger
The user can select a signal to be monitored by a peak value logger. The logger records
the peak value of the signal along with the time the peak occurred, as well as motor
current, DC voltage and motor speed at the time of the peak. The peak value is sampled
at 2 ms intervals.
