22-84 Speed at No-Flow [Hz]
Range: Function:
Application
dependent*
[Application dependant] 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:
Application
dependent*
[Application dependant] 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:
Application
dependent*
[Application dependant] 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* [Application dependant] Enter the pressure H
MIN
corresponding to Speed at No Flow in Reference/Feedback Units.
Please also see par. 22-82
Work Point Calculation
point D.
22-88 Pressure at Rated Speed
Range: Function:
999999.999
*
[Application dependant] 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:
Application
dependent*
[Application dependant] Resolution 1 RPM.
The speed of the motor at which the flow is zero and the 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.
