ENERGY

(Continued)
SAVED kW HOURS (45.03) Default: Read Only
Range: 0.0 - 999.9 kWh
Energy saved in kWh compared to direct-on-line motor connection.
If the internal brake chopper of the drive is enabled, all energy fed by
the motor to the drive is assumed to be converted into heat, but the
calculation still records savings made by controlling the speed. If the
chopper is disabled, then
regenerated energy from the motor is also recorded here. When
this parameter rolls over, parameter 45.02 Saved MW hours is
incremented.
Fieldbus Equivalent: 10 = 1 kWh
SAVED MONEY X1000 (45.05) Default: Read Only
Range: 0 - 294967295 thousands
Monetary savings in thousands compared to direct-on-line motor
connection. This parameter is incremented when 45.06 Saved money
rolls over. The currency is defined by parameter 45.17 Tariff currency
unit.
SAVED MONEY (45.06) Default: Read Only
Range: 0.00 - 999.99 units
Monetary savings compared to direct-on-line motor connection.
This value is a calculated by multiplying the saved energy in kWh
by the currently active energy tariff (45.14 Tariff selection). When
this parameter rolls over, parameter 45.05 Saved money x1000
is incremented. The currency is defined by parameter 45.17 Tariff
currency unit.
CO2 REDUCTION IN
KILOTONS (45.08)
Default:
Read Only
Range: 0 - 65535 metric kilotons
Reduction in CO2 emissions in metric kilotons compared to direct-
on-line motor connection. This value is incremented when parameter
45.09 CO2 reduction in tons rolls over.
CO2 REDUCTION IN TONS
(45.09)
Default: Read Only
Range: 0.0 - 999.9 metric tons
Reduction in CO2 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).
When this parameter rolls over, parameter 45.08 CO2 reduction in
kilotons is incremented.
ENERGY OPTIMIZER (45.11) Default: 0 (Disable)
Range: 0, 1
0 (Disable) Energy optimization disabled
1 (Enable) Energy optimization enabled
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.
