7.2.4.1.2 Parameterisation of the dynamic pressure setpoint compensation function
on PumpDrive Advanced
If the dynamic pressure setpoint compensation function is to be used in a multiple
pump configuration, ensure that the maximum number of pumps running
simultaneously
3-12-5-1
is set properly to match requirements (⇨ Section 7.1.3 Page
62) .
The following parameters are required for parameterisation of the dynamic pressure
setpoint compensation function on a PumpDrive Advanced model using flow rate
estimation based on the speed or the power:

The parameters for setting the dynamic pressure setpoint compensation function on
a PumpDrive Advanced model using flow rate estimation based on the speed must be
configured as follows:
