Group 45: ENERGY SAVING
This group defines the setup of calculation and optimization of
energy savings.
Note: The values of the saved energy parameters 0174 SAVED
KWH, 0175 SAVED MWH, 0176 SAVED AMOUNT 1, 0177 SAVED
AMOUNT 2, and 0178 SAVED CO2 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.
Code Description Range
4502 ENERGY PRICE 0…655.35
Price of energy per kWh.
• Used for reference when energy savings are calculated.
• See parameters 0174
SAVED KWH, 0175 SAVED MWH, 0176 SAVED
AMOUNT 1, 0177 SAVED AMOUNT 2 and 0178 SAVED CO2 (reduction on
carbon dioxide emissions in tn).
4507 CO2 CONV FACTOR 0.0…10.0
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 CO2 (reduction on carbon dioxide
emissions in tn).
4508 PUMP POWER 0.0…1000.0%
Pump power (as a percentage of the nominal motor power) when
connected directly to supply (DOL).
• Used for reference when energy savings are calculated.
• See parameters 0174
SAVED KWH, 0175 SAVED MWH, 0176 SAVED
AMOUNT 1, 0177 SAVED AMOUNT 2 and 0178 SAVED CO2.
• 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.
4509 ENERGY RESET 0=DONE,
1=RESET
Resets energy calculators 0174
SAVED KWH, 0175 SAVED MWH, 0176
SAVED AMOUNT 1, 0177 SAVED AMOUNT 2 and 0178 SAVED CO2.
