Description
Flow characteristic
Factory setting of the flow characteristic
To set the characteristic, you require the following data from the machine manufactur-
er for each speed interpolation point:
The flow rate of the fluid-flow machine associated with the 5 selected converter
•
speeds
The power drawn at constant speed associated with the five flow rates corre-
•
sponds to the line frequency and mechanical throttling of the flow rate.
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.
