3.14.4 20-9* PI Controller
20-91 PI Anti Windup
Option: Function:
[0] O 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
Range: Function:
0.50 * [0 - 10 ] Enter the process controller proportional gain.
Quick control is obtained at high
amplication.
However, if
amplication
is too high, the
process may become unstable.
20-94 PI Integral Time
Range: Function:
20 s * [0.10 -
9999 s]
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.
20-97 PI Feed Forward Factor
Range: Function:
0 % * [0 -
400 %]
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 aect only the remaining fraction of the
control signal. The FF factor can increase
dynamic performance.
