NOTE!
Sleep mode will not be active when Local Reference is active (set speed manually by means of arrow buttons on the LCP). See par.
3-13
.
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 command (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 override 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
has been set for RPM (parameter not visible if Hz selected).
Only to be used if par.1-00
is set for open-loop and speed reference is applied
by an external controller.
Set the reference speed at which sleep mode should be canceled.
22-43 Wake-up Speed [Hz]
Range:
Function:
0 Hz*
[par. 4-12 - par. 4-14 Hz]
To be used if par.0-02
has been set for Hz (parameter not visible if RPM selected).
Only to be used if par.1-00
is set for open-loop and speed reference is applied
by an external controller controlling the pressure.
Set the reference speed at which sleep mode should be canceled.
22-44 Wake-up Ref./FB Difference
Range:
Function:
10 %*
[0 - 100 %]
Only to be used if par.1-00
is set for closed-loop and the integrated PI controller
is used for controlling the pressure.
Set the pressure drop allowed in percentage of setpoint for the pressure (Pset) before canceling 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
, the value set in par.22-44
will automatically be added.
