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 converter speeds
• At constant speed, the power drawn which is associated with the 5 flow rates corresponds to
the line frequency and mechanical throttling of the flow rate.

[0] Energy consumption since the last reset.
[1] Energy drawn since the last reset.
[2] Energy fed back since the last reset.
r0039 serves as reference signal of r0042.
Setting p0040 = 1 to reset the display in r0039 and
r0041.
Factory setting: 0
Displays the saved energy referred to 100 operat‐
ing hours. For an operating time of below 100
hours, the display is interpolated up to 100 hours.
[0] Energy consumption since the last reset.
[1] Energy drawn since the last reset.
[2] Energy fed back since the last reset.
For display as process variable. Enable with p0043.
Sets the signal source (BI: p0043 = 1 signal) to en‐
able/reset the process energy display in r0042.
Factory setting: 0
Specifies the power (P) of point 1 as a [%].
Factory setting: 25
Specifies the speed (n) of point 1 as a [%].
Factory setting: 0
Specifies the power (P) of point 2 as a [%].
Factory setting: 50
