Signal supervision
Six signals can be selected to be supervised by this function. Whenever a supervised
signal exceeds or falls below predefined limits, a bit in 32.01 Supervision status is
activated, and a warning or fault generated.
The supervised signal is low-pass filtered.

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 93).
In addition, there are counters that show energy consumption in kWh of the current
and previous hour as well as the current and previous day.
The amount of energy that has passed through the drive (in either direction) is
counted and shown full as GWh, MWh and kWh. The cumulative energy is also
shown as full kWh. All these counters are resettable.
Note: The accuracy of the energy savings calculation is directly dependent on the
accuracy of the reference motor power given in parameter 45.19 Comparison power.
