Adapting the pump, fan, or compressor characteristic
The 5 interpolation points of the pump, fan, or compressor characteristic are entered using
parameters p3320 to p3329. This characteristic can be configured individually for each drive
data set.
Table 9- 7
Interpolation point
Note
Consequences of not adjusting the pump, fan, or compressor curve
If the interpolation points of the pump, fan, or compressor curve are not adapted, the factory
setting will be used to calculate the energy saving indicator. The values of the factory setting
could then deviate from the equipment characteristic and cause incorrect calculation of the
actual energy savings.
Energy saving indication
The energy saving is displayed in parameter r0041.
By setting p0040 = 1, the value of parameter r0041 is reset to 0. Parameter p0040 is then
automatically set to 0.
