Function:
Set the desired minimum time for staying in Sleep Mode. This
will override any wake up conditions.
Function:
Motor Speed Unit
To be used if par. 0-02,
(parameter not visible if Hz selected). Only to be used if par.
Configuration Mode
1-00, , is set for Open Loop and speed ref-
erence is applied by an external controller.
Set the reference speed at which the Sleep Mode should be
cancelled.
Function:
Motor Speed Unit
To be used if par. 0-02,
(parameter not visible if RPM selected). Only to be used if par.
1-00, Configuration Mode , is set for Open Loop and speed ref-
erence is applied by an external controller controlling the pres-
sure.
Set the reference speed at which the Sleep Mode should be
cancelled.
Function:
Only to be used if par. 1-00,
Closed Loop and the integrated PI controller is used for con-
trolling 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 con-
troller is set for inverse control in par. 20-71,
Normal/Inverse Control
22-44 will automatically be added.
Function:
Only to be used if par. 1-00,
Closed Loop and the integrated PI controller is used. In systems
with e.g. constant pressure control, it is advantageous to in-
crease 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.
