related*
[ par. 22-83 -
60000 RPM]
Resolution 1 RPM.
Only visible when
parameter 22-82 Work Point
Calculation is set to [0] Disabled.
Enter the motor speed in RPM at
which the system design working
point is achieved. Alternatively,
enter the speed in Hz in
parameter 22-86 Speed at Design
Point [Hz]. If parameter 0-02 Motor
Speed Unit is set to RPM,
parameter 22-83 Speed at No-Flow
[RPM] should also be used.

[ par. 22-84 -
par. 4-19 Hz]
Resolution 0.033 Hz.
Only visible when
parameter 22-82 Work Point
Calculation is set to [0] Disabled.
Enter the motor speed in Hz at
which the system design working
point is achieved. Alternatively,
enter the speed in RPM in
parameter 22-85 Speed at Design
Point [RPM]. If parameter 0-02 Motor
Speed Unit is set to Hz,
parameter 22-83 Speed at No-Flow
[RPM] should also be used.
22-87 Pressure at No-Flow Speed
Range: Function:
0* [ 0 - par.
22-88 ]
Enter the pressure H
MIN
corresponding to speed at no-ow
in reference/feedback units.
22-88 Pressure at Rated Speed

*
[ par. 22-87 -
999999.999 ]
Enter the value corresponding to
the pressure at rated speed, in
reference/feedback units. This value
can be dened using the pump
datasheet.
22-89 Flow at Design Point
Also see parameter 22-82 Work Point Calculation.
Range: Function:
0* [0 -
999999.999 ]
Enter the value corresponding to
the ow at design point. No units
necessary.
