2 are derived from
subtracting the drive’s energy consumed from the direct-on-line (DOL) consumption
calculated on the basis of parameter 4508
PUMP POWER
. As such, the accuracy of
the values is dependent on the accuracy of the power estimate entered in that
parameter.

2 (reduction on carbon dioxide emissions in tn).
4507 CO2 CONV FACTOR
Conversion factor for converting energy into CO2 emissions (kg/kWh or tn/MWh). Used for multiplying the saved
energy in MWh to calculate the value of parameter 0178
SAVED CO
2 (reduction on carbon dioxide emissions in tn).
4508 PUMP POWER
Pump power (as a percentage of the nominal motor power) when connected directly to supply (DOL).
