22-83 Speed at No-Flow [RPM]
Range: Function:
Applica-
tion
depend-

*
[Applica-
tion
dependant]
Resolution 1 RPM.
The speed of the motor at which flow Is
zero and minimum pressure H
MIN
is
achieved should be entered here in RPM.
Alternatively, the speed in Hz can be
entered in par. 22-84 Speed at No-Flow
[Hz]. If it has been decided to use RPM in
par. 0-02 Motor Speed Unit then
par. 22-85 Speed at Design Point [RPM]
should also be used. Closing the valves
and reducing the speed until minimum
pressure H
MIN
is achieved will determine
this value.
22-84 Speed at No-Flow [Hz]
Range: Function:

[Applica-
tion
dependant]
Resolution 0.033 Hz.
The speed of the motor at which flow
has effectively stopped and minimum
pressure H
MIN
is achieved should be
entered here in Hz. Alternatively, the
speed in RPM can be entered in
par. 22-83 Speed at No-Flow [RPM]. If it
has been decided to use Hz in
par. 0-02 Motor Speed Unit then
par. 22-86 Speed at Design Point [Hz]
should also be used. Closing the valves
and reducing the speed until minimum
pressure H
MIN
is achieved will determine
this value.
22-85 Speed at Design Point [RPM]
Range: Function:

Resolution 1 RPM.
Only visible when par. 22-82 Work Point
Calculation is set to Disable. The speed
of the motor at 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 at Design Point [Hz]. If it
has been decided to use RPM in
par. 0-02 Motor Speed Unit then
par. 22-83 Speed at No-Flow [RPM]
should also be used.

Resolution 0.033 Hz.
Only visible when par. 22-82 Work Point
Calculation is set to Disable. The speed
of the motor at 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 Speed at Design Point [RPM]. If
it has been decided to use Hz in
par. 0-02 Motor Speed Unit, then
par. 22-83 Speed at No-Flow [RPM]
should also be used.
22-87 Pressure at No-Flow Speed
Range: Function:
0.000 * [Application
dependant]
Enter the pressure H
MIN
correspond-
ing to Speed at No Flow in
Reference/Feedback Units.
Please also see par. 22-82 Work Point Calculation point D.
22-88 Pressure at Rated Speed
Range: Function:
999999.999 * [Application
dependant]
Enter the value corresponding to
the Pressure at Rated Speed, in
Reference/Feedback Units. This
value can be defined using the
pump datasheet.
Please also see par. 22-82 Work Point Calculation point A.
22-89 Flow at Design Point
Range: Function:
0.000 * [0.000 - 999999.999 ] Enter the value corresponding to
the Flow at Design Point. No units
necessary.
Please also see par. 22-82 Work Point Calculation point C.
22-90 Flow at Rated Speed
Range: Function:
0.000 * [0.000 - 999999.999 ] Enter the value corresponding to
Flow at Rated Speed. This value can
be defined using the pump
datasheet.
