20-94 PID Integral Time
Range: Function:
20.00 s* [0.01 - 10000.00 s] Over time, the integrator accumulates a contribution to the output from the PID controller as long
as there is a deviation between the Reference/Setpoint and feedback signals. The contribution is
proportional to the size of the deviation. This ensures that the deviation (error) approaches zero.
Quick response on any deviation is obtained when the integral time is set to a low value. Setting it
too low, however, may cause the control to become unstable.
The value set, is the time needed for the integrator to add the same contribution as the proportional
part for a certain deviation.
If the value is set to 10,000, the controller will act as a pure proportional controller with a P-band
based on the value set in par.20-93
PID Proportional Gain
. When no deviation is present, the output
from the proportional controller will be 0.
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
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.
NB!
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.
22-75 Short Cycle Protection
Option: Function:
[0] Disabled Timer set in
Interval Between Starts
, par. 22-76 is disabled.
[1] Enabled Timer set in
Interval between Starts
, par. 22-76 is enabled.
