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
• A load analyzer showing the load profile of the drive (see separate section on
page 124).
Note: The accuracy of the energy savings calculation is directly dependent on the
accuracy of the reference motor power given in parameter

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.
Amplitude loggers
The control program has two amplitude loggers.
For amplitude logger 2, the user can select a signal to be sampled at 200 ms
intervals, and specify a value that corresponds to 100%. The collected samples are
sorted into 10 read-only parameters according to their amplitude. Each parameter
represents an amplitude range 10 percentage points wide, and displays the
percentage of the collected samples that have fallen within that range. Note that the
lowest range also contains the negative values (if any), while the highest range also
contains the values above 100%.
