96 Program featuresDiagnostics Signal supervisionSix signals can be selected to be supervised by this function. Whenever a supervisedsignal exceeds or falls below predefined limits, a bit in 32.01 Supervision status isactivated, and a warning or fault generated.The supervised signal is low-pass filtered.Parameters and diagnosticsParameters: group 32 Supervision. Energy saving calculatorsThis feature consists of the following functionalities:• An energy optimizer that adjusts the motor flux in such a way that the total systemefficiency is maximized• A counter that monitors used and saved energy by the motor and displays them inkWh, currency or volume of CO 2 emissions, and• A load analyzer showing the load profile of the drive (see section Load analyzeron page 96).In addition, there are counters that show energy consumption in kWh of the currentand previous hour as well as the current and previous day.Note: The accuracy of the energy savings calculation is directly dependent on theaccuracy of the reference motor power given in parameter 45.19 Comparison power.Parameters and diagnosticsParameters: group 45 Energy efficiency, 01.50 Current hour kWh, 01.51 Previoushour kWh, 01.52 Current day kWh and 01.53 Previous day kWh. Load analyzerPeak value loggerThe user can select a signal to be monitored by a peak value logger. The loggerrecords the peak value of the signal along with the time the peak occurred, as well asmotor current, DC voltage and motor speed at the time of the peak. The peak value issampled at 2 ms intervals.Amplitude loggersThe control program has two amplitude loggers.
