Energy saving
Energy saving tools calculate energy saved in kWh and MWh, energy saved in local
currency as well as reduction in CO
2
emission, all compared to the situation when the
pump is connected directly to the supply.
Two actual signals, 0176 SAVED AMOUNT 1 and 0177 SAVED AMOUNT 2 are used
to store the energy saved in local currency. To find out the total saved energy in
currency units, add the value of signal 0177 multiplied by 1000 to the value of signal
0176.
Example:
0176 SAVED AMOUNT 1 = 123.4
0177 SAVED AMOUNT 2 = 5
Total saved energy = 5 · 1000 + 123.4 = 5123.4 currency units.
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.
