Function:
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
from the proportional controller will be 0.
Function:
Set the desired minimum running time for the motor after a start command (digital input or Bus)
before entering Sleep Mode.
Function:
Set the desired Minimum Time for staying in Sleep Mode. This will override any wake up conditions.
Function:
To be used if par. 0-02
Only to be used if par.1-00
by an external controller.
Set the reference speed at which the Sleep Mode should be cancelled.
Function:
To be used if par. 0-02
Only to be used if par.1-00
by an external controller controlling the pressure.
Set the reference speed at which the Sleep Mode should be cancelled.
Function:
Only to be used if par.1-00
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.
