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

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
emissions in tn).
4508 PUMP POWER
Pump power (as a percentage of the nominal motor power) when
connected directly to supply (DOL).
• Used for reference when energy savings are calculated.

• It is possible to use this parameter as the reference power also for
other applications than pumps. The reference power can also be
some other constant power than a motor connected directly online.
