22-83 Speed at No-Flow [RPM]
Range:
Function:
300. RPM* [0 - par. 22-85 RPM]
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
. If it has been decided to use RPM in par.0-02
then par.22-85
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:
50.0 Hz*
[0.0 - par. 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 par.22-83
. If it has been decided to use Hz in par.0-02
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* [par. 22-83 - 60000. RPM]
Resolution 1 RPM.
Only visible when par.22-82
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
. If it has been decided to
use RPM in par.0-02
then par.22-83
should also be used.
22-86 Speed at Design Point [Hz]
Range:
Function:
50/60.0
Hz*
[par. 22-84 - par. 4-19 Hz]
Resolution 0.033 Hz.
Only visible when par.22-82
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
. If it has been decided to
use Hz in par.0-02
should also be used.
22-87 Pressure at No-Flow Speed
Range:
Function:
0.000 N/A* [0.000 - par. 22-88 N/A]
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
N/A*
[par. 22-87 - 999999.999 N/A]
Enter the value corresponding to the Pressure at Rated Speed, in Reference/Feedback Units. This
value can be defined using the pump datasheet.
22-90 Flow at Rated Speed
Range:
Function:
0.000 N/A* [0.000 - 999999.999 N/A]
Enter the value corresponding to Flow at Rated Speed. This value can be defined using the pump
datasheet.
