VLT Refrigeration Drive FC 103
Function:
Resolution 0.033 Hz.
Enter the motor speed in Hz at which flow
has effectively stopped and minimum
pressure H is achieved. Alternatively,
MIN
enter the speed in RPM in
parameter 22-83 Speed at No-Flow [RPM]. If
parameter 0-02 Motor Speed Unit is set to
Hz, parameter 22-86 Speed at Design Point
[Hz] should also be used. Closing the valves
and reducing the speed until minimum
pressure H is achieved determines this
MIN
value.
Function:
Resolution 1 RPM.
Only visible when parameter 22-82 Work
Point Calculation is set to [0] Disabled.
Enter the motor speed in RPM at which
the system design working point is
achieved. Alternatively, enter the speed in
Hz in parameter 22-86 Speed at Design
Point [Hz]. If parameter 0-02 Motor Speed
Unit is set to RPM, parameter 22-83 Speed
at No-Flow [RPM] should also be used.
Function:
Resolution 0.033 Hz.
Only visible when parameter 22-82 Work
Point Calculation is set to [0] Disabled. Enter
the motor speed in Hz at which the
system design working point is achieved.
Alternatively, enter the speed in RPM in
parameter 22-85 Speed at Design Point
[RPM]. If parameter 0-02 Motor Speed Unit is
set to Hz, parameter 22-83 Speed at No-
Flow [RPM] should also be used.
Function:
corresponding to

speed at no-flow in reference/feedback
units.
Function:
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
Also see parameter 22-82 Work Point Calculation.
Range: Function:
0 [0 - 999999.999] Enter the value corresponding to the flow
*
at design point. No units necessary.
22-90 Flow at Rated Speed
Also, see parameter 22-82 Work Point Calculation.
Range: Function:
0 [0 - 999999.999] Enter the value corresponding to flow at
*
rated speed. This value can be defined
using the pump datasheet.
