4.15.6 20-9* PI Controller
Parameters for configuring the Process PI controller.
20-91 PI Anti Windup
Default value: [1] On
Conversion index: -
Table 377: Option:
[0] Off Continue regulation of an error even when the output frequency cannot be increased or decreased.
[1] On Cease regulation of an error when the output frequency can no longer be adjusted.
20-93 PI Proportional Gain
Default value: 0.50
Conversion index: -2
Enter the process controller proportional gain. Quick control is obtained at high amplification. However, if amplification is too high,
the process may become unstable.
Table 378: Range:
Min: 0
20-94 PI Integral Time
Default value: 20 s
Conversion index: -2
Enter the process controller integral time. Obtain quick control through a short integral time, though if the integral time is too short,
the process becomes unstable. An excessively long integral time disables the integral action.
Table 379: Range:
Min: 0.10 s
20-97 PI Feed Forward Factor
Default value: 0%
Conversion index: 0
Enter the PI feed forward factor. The FF factor sends a constant fraction of the reference signal to bypass PI control. Therefore, the PI
can affect only the remaining fraction of the control signal. The FF factor can increase dynamic performance.
