22-83 Speed at No-Flow [RPM]
Range:
300. RPM* [0 - par. 22-85 RPM]
22-90 Flow at Rated Speed
Range:

Function:
Resolution 0.033 Hz.
The speed of the motor at which flow has effectively stopped and minimum pressure H
should be entered here in Hz. Alternatively, the speed in RPM can be entered in par. 22-83
at No-Flow [RPM] . If it has been decided to use Hz in par. 0-02 Motor
22-86 Speed at Design Point [Hz]
until minimum pressure H is achieved will determine this value.

Only visible when par. 22-82 Work Point Calculation
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

Speed Unit
use Hz in par. 0-02 Motor
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:
Resolution 1 RPM.
The speed of the motor at which flow Is zero and minimum pressure H
entered here in RPM. Alternatively, the speed in Hz can be entered in par. 22-84
[Hz]
. If it has been decided to use RPM in par. 0-02 Motor
Design Point [RPM]
should also be used. Closing the valves and reducing the speed until minimum
pressure H is achieved will determine this value.
MIN
Function:
Enter the value corresponding to Flow at Rated Speed. This value can be defined using the pump
datasheet.
