Configuration possibilities, overview:
Internal PI Controller
(par.1-00
Configuration Mode: Closed loop)
External PI Controller or manual control
(par.1-00
Configuration Mode: Open loop)
Sleep mode Wake up Sleep mode Wake up
No Flow detection (pumps only) Yes Yes (except manual set-
ting of speed)
Low speed detection Yes Yes
External signal Yes Yes
Pressure/Temperature (trans-
mitter connected)
Yes No
Output frequency No Yes
Note
Sleep Mode will not be active when Local Reference is active (set speed manually by means of arrow buttons
on the keypad). See par.3-13
Reference Site.
Does not work in Hand-mode. Auto set-up in open loop must be carried out before setting input/output in closed
loop.
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:
0 RPM* [par. 4-11 - par. 4-13 RPM] 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:
0 Hz* [par. 4-12 - par. 4-14 Hz] 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.
NOTE: 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 automat-
ically be added.
