Program features 85
îš„ Energy saving calculator
This feature consists of three functionalities:
• An energy optimizer that adjusts the motor flux in such a way that the total
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
emission, and
• A load analyzer showing the load profile of the drive (see page 85).
Note: The accuracy of the energy savings calculation is directly dependent on the
accuracy of the reference motor power given in parameter 45.08 Reference power.

îš„ Load analyzer
Peak value logger
The user can select a signal to be monitored by the 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.
Amplitude loggers
The drive has two amplitude loggers.
For amplitude logger 2, the user can select a signal to be sampled at 200 ms intervals
when the drive is running, 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 fall within that range.
