7.2.2 Functions based on pump characteristic curves
7.2.2.1 Matching PumpDrive to the pump (for PumpDrive Advanced only)
If PumpDrive is not pre-configured at the factory, the pump characteristic curve is
defined for PumpDrive using 6 Q, H, and P data points. The following illustration
shows the parameters of the respective data points using a pump characteristic curve
as an example. The input steps of the parameters are designated 1 to 4.
