Parameters
3.14.4 20-9* PI Controller
20-91 PI Anti Windup
Option: Function:
[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
Range: Function:
0.50 [0 - 10 ] Enter the process controller proportional gain.
*
Quick control is obtained at high amplification.
However, if amplification is too high, the
process may become unstable.
20-94 PI Integral Time
Range: Function:
20 s [0.10 - Enter the process controller integral time.
*
9999 s] 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 - Enter the PI feed forward factor. The FF factor
*
400 %] 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.
