0325 FRQ. LIFT
Frequency limit for required lift value
30.0 Hz
Possible settings: 0.0 Hz – 70.0 Hz
Control according to a system curve (increase of the set pressure, depending on the flow rate/speed to
cover friction losses).
The setting determines the output-frequency where the set pressure starts to be increased. The right
setting should be equal to the frequency when the pump reaches the set pressure at zero flow (Can be
determined by using the JOG MODE [0305]).
0330
0330 LIFT AMOUNT
Lift amount for required lift value
0.0 %
Possible settings: 0.0 – 200.0%
This value states how much the set value should be continually increased, till the maximum speed (maxi-
mum volume) is reached.
Application Example:
1) Enter the set pressure (see main menu
parameter REQ. VAL [02]).
2) Find out the frequency where set pres-
sure is reached at zero demand (use
JOG MODE [0305]) and set the value in
parameter FREQU. LIFTING.
3) Set desired lift at maximum speed in % of
the set pressure in the parameter LIFT-
AMOUNT [0330].
