Parameters
Group 45: ENERGY SAVING
This group defines the setup of calculation and optimization of energy savings.
Note: The values of 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
4502 ENERGY PRICE
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
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
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
Resets energy calculators 0174
SAVED KWH, 0175 SAVED MWH, 0176 SAVED AMOUNT 1, 0177 SAVED AMOUNT 2 and
0178
SAVED CO2.
