[0-Value of par.
22-85]
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. Al-
ternatively, 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
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:
10 Hz
*
[0 - Value of par.
22-86]
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 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:
1500
RPM
*
[0 - 60,000]
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. Al-
ternatively, 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 then par. 22-83 Speed No Flow [RPM] should also be used.
22-86 Speed at Design Point [Hz]
Range: Function:
50 Hz
*
[0 - 1000 Hz]
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. Alter-
