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.
22-89 Flow at Design Point
Range: Function:
0.000 N/A* [0.000 - 999999.999 N/A] Enter the value corresponding to the Flow at Design Point. No units necessary.
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.
