4.8.3. 7-3* Process PI Control
7-30 Process PI Normal/Inverse Control
Option: Function:
[0]
*
Normal Feedback larger than setpoint result in a speed reduction.
Feedback less than setpoint result in a speed increase.
[1] Inverse Feedback larger than setpoint result in a speed increase.
Feedback less than setpoint result in a speed reduction.
7-31 Process PI Anti Windup
Option: Function:
[0] Disable Regulation of a given error will continue even when the output
frequency cannot be increased/decreased.
[1]
*
Enable PI-controller ceases from regulating a given error when the out-
put frequency cannot be increased/decreased.
7-32 Process PI Start Speed
Range: Function:
0.0 Hz
*
[0.0 - 200.0 Hz] Until the set motor speed has been reached the frequency con-
verter operates in Open Loop mode.
7-33 Process PI Proportional Gain
Option: Function:
[0.01]
*
0.00 - 10.00 Enter the value for the P proportional gain, i.e. the multiplication
factor of the error between the set point and the feedback sig-
nal.
Note! 0.00 = Off.
