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.
Parameters and diagnostics
Parameters: group 32 Supervision.
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 section Load analyzer
on page 96).
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.
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.
Parameters and diagnostics
Parameters: group 45 Energy efficiency, 01.50 Current hour kWh, 01.51 Previous
hour kWh, 01.52 Current day kWh and 01.53 Previous day kWh.
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.
