Do not set par. 14-20 Reset Mode, to [13] Infinite auto reset, when par. 22-23 No-Flow Functionis set to [3] Alarm.
Doing so will cause the drive to continuously cycle between running and stopping when a No Flow condition is detected.
If the drive is equipped with a constant speed bypass with an automatic bypass function that starts the bypass if the
drive experiences a persistent alarm condition, be sure to disable the bypass’s automatic bypass function, if [3] Alarm
is selected as the No-Flow Function.
22-24 No-Flow Delay
Range: Function:
10 s* [1 - 600 s] Set the time Low Power/Low Speed must stay detected to activate signal
for actions. If detection disappears before run out of the timer, the timer
will be reset.
22-40 Minimum Run Time
Range: Function:
10 s* [0 - 600 s] Set the desired minimum running time for the motor after a start com-
mand (digital input or Bus) before entering Sleep Mode.
22-41 Minimum Sleep Time
Range: Function:
10 s* [0 - 600 s] Set the desired Minimum Time for staying in Sleep Mode. This will over-
ride any wake up conditions.
22-42 Wake-up Speed [RPM]
Range: Function:
Applica-
tion de-
pend-
ent*
[Application dependant] To be used if par. 0-02
Motor Speed Unit has been set for RPM (parameter
not visible if Hz 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.
Set the reference speed at which the Sleep Mode should be cancelled.
22-43 Wake-up Speed [Hz]
Range: Function:
Applica-
tion de-
pend-
ent*
[Application dependant] 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.
22-44 Wake-up Ref./FB Difference
Range: Function:
10 %* [0 - 100 %] 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.
If used in application where the integrated PI controller is set for inverse control (e.g. cooling tower applications) in
par. 20-71
PID Performance, the value set in par. 22-44 Wake-up Ref./FB Difference will automatically be added.
