[ 0.0 -

22-86 Hz]
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
22-83 Speed at No-Flow [RPM]. If it has
been decided to use Hz in 0-02 Motor
Speed Unit then 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.

Resolution 1 RPM.
Only visible when 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
22-86 Speed at Design Point [Hz]. If it has
been decided to use RPM in 0-02 Motor
Speed Unit then 22-83 Speed at No-Flow
[RPM] should also be used.

Resolution 0.033 Hz.
Only visible when 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
22-85 Speed at Design Point [RPM]. If it
has been decided to use Hz in
0-02 Motor Speed Unit, then 22-83 Speed
at No-Flow [RPM] should also be used.
22-87 Pressure at No-Flow Speed
Range: Function:
0.000 * [ 0.000 - par.
22-88 ]
Enter the pressure H
MIN
corresponding to Speed at No Flow
in Reference/Feedback Units.

22-88 Pressure at Rated Speed
Range: Function:
999999.999 * [ par. 22-87 -
999999.999 ]
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 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.

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.
