6.39 Calculating the energy saving for fluid flow machines
Description
Energy display [kWh]
[0] Energy balance
Energy usage since the last reset
[1] Energy drawn since the last reset
[2] Energy fed back since the last reset
Reset energy consumption display
A signal change 0 → 1 sets r0039[0...2] = 0, r0041 = 0 and r0042 = 0.
Energy consumption saved (kWh)
Energy saved referred to 100 operating hours.
For less than 100 operating hours, the inverter interpolates the energy saving to 100
operating hours.
CO: Process energy display [1 ≙ 1 Wh]
For display as process variable. Enable with p0043.
[0] Energy balance
Energy consumption since the last reset.
[1] Energy drawn since the last reset
[2] Energy fed back since the last reset.
BI: Enable energy usage display
1 signal: Process energy display is active in r0042.
Flow characteristic
Factory setting of the flow characteristic
To set the characteristic, you require the following data from the machine manufacturer
for each speed interpolation point:
● The flow rate of the fluid-flow machine associated with the 5 selected inverter speeds
● The power drawn at constant speed associated with the five flow rates corresponds
to the line frequency and mechanical throttling of the flow rate.
