The calculation of drive losses depends on input and output power calculations. Due to this
dependency it is important to ensure that the following values are correctly set:
• Drive input and output rated values, voltage and current:
– Rated input voltage (2010)
– Rated input current (2020)
– Rated output voltage (2030)
– Rated output current (2040)
• Drive input scalers
– Input current scaler (3030)
– Input voltage scaler (3040)
• Input CT turns ratio
– CT secondary turns (3035)
• Output scalers
– Output current scaler (3440)
– Output voltage scaler (3450)
• Low Freq Wo (3070)
