Parameters 255
45.10 Total saved CO2 Reduction in CO
2
emissions in metric tons compared to
direct-on-line motor connection. This value is calculated
by multiplying the saved energy in MWh by the value of
parameter 45.18 CO2 conversion factor (by default, 0.5
metric tons/MWh).
This parameter is read-only (see parameter 45.21 Energy
calculations reset).

45.11 Energy optimizer Enables/disables the energy optimization function. The
function optimizes the motor flux so that total energy
consumption and motor noise level are reduced when the
drive operates below the nominal load. The total efficiency
(motor and drive) can be improved by 1…20% depending
on load torque and speed.
Note: With a permanent magnet motor or a synchronous
reluctance motor, energy optimization is always enabled
regardless of this parameter.

45.12 Energy tariff 1 Defines energy tariff 1 (price of energy per kWh).
Depending on the setting of parameter 45.14 Tari ff
selection, either this value or 45.13 Energy tariff 2 is used
for reference when monetary savings are calculated.
Note: Tariffs are read only at the instant of selection, and
are not applied retroactively.

45.18 CO2 conversion factor Defines a factor for conversion of saved energy into CO
2
emissions (kg/kWh or tn/MWh). For example,
45.10 Total saved CO2 = 45.02 Saved kW hours × 45.18
CO2 conversion factor (tn/MWh).
