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 HMIN is achievedshould be entered here in Hz. Alternatively, the speed in RPM can be entered in par.22-83Speedat No-Flow [RPM]. If it has been decided to use Hz in par. 0-02Motor Speed Unit, then par.22-86Speed at Design Point [Hz] should also be used. Closing the valves and reducing the speeduntil minimum pressure HMIN 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.22-82Work Point Calculation is set toDisable. The speed of the motor atwhich the system design working point is achieved should be entered here in RPM. Alternatively,the speed in Hz can be entered in par.22-86Speed at Design Point [Hz]. If it has been decided touse RPM in par. 0-02Motor Speed Unit, then par.22-83Speed at No-Flow [RPM] should also beused.22-86 Speed at Design Point [Hz]Range: Function:50/60.0Hz*[par. 22-84 - par. 4-19 Hz] Resolution 0.033 Hz.Only visible when par.22-82Work Point Calculation is set toDisable. The speed of the motor atwhich the system design working point is achieved should be entered here in Hz. Alternatively, thespeed in RPM can be entered in par.22-85Speed at Design Point [RPM]. If it has been decided touse Hz in par. 0-02Motor Speed Unit, then par.22-83Speed at No-Flow [RPM] should also be used.22-87 Pressure at No-Flow SpeedRange: Function:0.000 N/A* [0.000 - par. 22-88 N/A] Enter the pressure HMIN corresponding to speed at no-flow in reference/feedback units.22-88 Pressure at Rated SpeedRange: Function:999999.999N/A*[par. 22-87 - 999999.999 N/A] Enter the value corresponding to the pressure at rated speed in reference/feedback units. This valuecan 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 the flow is zero and the minimum pressure H MIN is achieved shouldbe entered here in RPM. Alternatively, the speed in Hz can be entered in par.22-84Speed at No-Flow [Hz]. If it has been decided to use RPM in par. 0-02Motor Speed Unit, then par.22-85Speedat Design Point [RPM] should also be used. Closing the valves and reducing the speed until minimumpressure H MIN is achieved will determine this value.22-90 Flow at Rated SpeedRange: 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 pumpdatasheet.8 How to program the adjustable frequencydriveVLT® AQUA DriveInstruction Manual8-42 MG.20.M5.22 - VLT® is a registered Danfoss trademark8
