[1]
7-32 Process PI Start Speed
Range:
*
0.0 Hz [0.0 - 200.0 Hz]
7-33 Process PI Proportional Gain
Option:
0.00 - 10.00
*
[0.01]
7-34 Process PI Integral Time
Range:
*
9999.00 s [0.10 - 9999.00 s]
Function:
Select input to function as feedback signal.
Function:
Feedback larger than setpoint result in a speed reduction.
Feedback less than setpoint result in a speed increase.
Feedback larger than setpoint result in a speed increase.
Feedback less than setpoint result in a speed reduction.
Function:
Regulation of a given error will continue even when the output frequency cannot be increased/decreased.
PI-controller ceases from regulating a given error when the output frequency cannot be increased/decreased.
Function:
Until the set motor speed has been reached the frequency converter operates in Open Loop mode.
Function:
Enter the value for the P proportional gain, i.e. the multiplication factor of the error between the set point and the
feedback signal.
Note! 0.00 = Off.
Function:
The integrator provides an increasing gain at a constant error between the set point and the feedback signal. The
integral time is the time needed by the integrator to reach the same gain as the proportional gain.
