22-44 Wake-up Ref./FB Difference
Range:
10%* [0-100%]
22-45 Setpoint Boost
Range:
0 %* [-100 - 100 %]
Function:
To be used if par. 0-03 Regional Settings has been set for North America (parameter not visible if
International selected).
Set power consumption at 85% speed level.
This function is used for storing values needed to tune No Flow Detection.
Function:
Set the desired minimum running time for the motor after a start command (digital input or Bus)
before entering Sleep Mode.
Function:
Set the desired Minimum Time for staying in Sleep Mode. This will override any wake up conditions.
Function:
Motor Speed Unit has been set for RPM (parameter not visible if Hz selected).
To be used if par. 0-02
Only to be used if par. 1-00 Configuration Mode is set for Open Loop and speed reference is applied
by an external controller.
Set the reference speed at which the Sleep Mode should be cancelled.
Function:
To be used if par. 0-02 Motor Speed Unit , has been set for Hz (parameter not visible if RPM selected).
Only to be used if par. 1-00 Configuration Mode , is set for Open Loop and speed reference is applied
by an external controller controlling the pressure.
Set the reference speed at which the Sleep Mode should be cancelled.
Function:
Only to be used if par. 1-00, Configuration Mode , is set for Closed Loop and the integrated PI
controller is used for controlling the pressure.
Set the pressure drop allowed in percentage of set point for the pressure (Pset) before cancelling
the Sleep Mode.
NB!
If used in application where the integrated PI controller is set for inverse control
PID, Normal/Inverse Control , the value set in par. 22-44 will au-
in par. 20-71,
tomatically be added.
Function:
Only to be used if par. 1-00 Configuration Mode , is set for Closed Loop and the integrated PI con-
troller is used. In systems with e.g. constant pressure control, it is advantageous to increase the
system pressure before the motor is stopped. This will extend the time in which the motor is stopped
and help to avoid frequent start/stop.
Set the desired over pressure/temperature in percentage of set point for the pressure (Pset)/tem-
perature before entering the Sleep Mode.
If setting for 5%, the boost pressure will be Pset*1.05. The negative values can be used for e.g.
cooling tower control where a negative change is needed.
