23-80 Power Reference Factor
Range: Function:
100 %* [0 - 100 %] Set the percentage of the rated
motor size (set in
parameter 1-20 Motor Power [kW] or
parameter 1-21 Motor Power [HP]),
which shows the average power
yielded at the time running with
xed speed (before upgrade with
variable-speed control).
Set a value dierent from 0 to start
counting.
23-81 Energy Cost
Range: Function:
1* [0 -
999999.99 ]
Set the actual cost for a kWh in
local currency. If the energy cost is
changed later on, it impacts the
calculation for the entire period.
23-82 Investment
Range: Function:
0* [0 -
999999999 ]
Set the value of the investment
spent on upgrading the plant with
speed control, in same currency as
used in parameter 23-81 Energy Cost.
23-83 Energy Savings
Range: Function:
0 kWh* [0 - 0 kWh] This parameter allows a readout of
the accumulated dierence
between the reference power and
the actual output power.
If motor size is set in hp
(parameter 1-21 Motor Power [HP]),
the equivalent kW value is used for
the energy savings.
23-84 Cost Savings
Range: Function:
0* [0 -
2147483647 ]
This parameter allows a readout of
the calculation based on the above
equation (in local currency).
23-85 CO2 Conversion Factor
Range: Function:
500 g* [0 - 1000 g] Enter the CO2 emission in grams
per 1 kWh of electrical energy
produced. Typical life-cycle
greenhouse-gas emission values for
dierent power sources are:
•
Renewable: 25 g.
•
Nuclear: 70 g.
23-85 CO2 Conversion Factor
Range: Function:
•
Natural gas: 350 g.
•
Oil: 800 g.
•
Coal: 1000 g.
For more precise emission values in
your region, contact your regional
environment agency.
23-86 CO2 Reduction
Range: Function:
0 kg* [0 - 0 kg] Shows the CO2 depletion in kg
based on the CO2 conversion factor
(parameter 23-85 CO2 Conversion
Factor) and saved energy
(parameter 23-83 Energy Savings).
