Danfoss VLT AQUA Drive FC 202 Operating Instructions

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
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:
1500. RPM* [par. 22-83 - 60000. RPM] 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.
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
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 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.
22-83 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
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.
22-90 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.
