Work Point Calculation
Only visible when par.22-82
which the system design working point is achieved should be entered here in RPM. Alternatively,
the speed in Hz can be entered in par.22-86
use RPM in par.0-02 Motor Speed Unit
Function:
Resolution 0.033 Hz.
Work Point Calculation
Only visible when par.22-82
which the system design working point is achieved should be entered here in Hz. Alternatively, the
speed in RPM can be entered in par.22-85
use Hz in par.0-02 Motor Speed Unit
Function:
Enter the pressure H corresponding to Speed at No Flow in Reference/Feedback Units.
MIN
Function:
Enter the value corresponding to the Pressure at Rated Speed, in Reference/Feedback Units. This
value can be defined using the pump datasheet.
Function:
Enter the value corresponding to the Flow at Design Point. No units necessary.
Function:
Enter the value corresponding to Flow at Rated Speed. This value can be defined using the pump
datasheet.
