23-81 Energy Cost
Range: Function:
1.00 N/A* [0.00 - 999999.99 N/A] Set the actual cost for a kWh in local currency. If the energy cost is changed later on it will impact
the calculation for the entire period.
23-82 Investment
Range: Function:
0 N/A* [0 - 999999999 N/A] Set the value of the investment spent on upgrading the plant with speed control, in same currency
as used in par. 23-81
Energy Cost .
23-83 Energy Savings
Range: Function:
0 kWh* [0 - 0 kWh] This parameter allows a readout of the accumulated difference between the reference power and
the actual output power.
If motor size set in Hp (par. 1-21
Motor Power [HP] ), the equivalent kW value will be used for the
Energy Savings.
23-84 Cost Savings
Range: Function:
0 N/A* [0 - 2147483647 N/A] This parameter allows a readout of the calculation based on the above equation (in local currency).
