20-81 PI Normal/ Inverse Control
[0] Normal
[1] Inverse
0
Select
[0] Normal
to set the process control to
increase the output speed when the process
error is positive. Select
[1] Inverse
to reduce
the output speed.
20-83 PI Start Speed [Hz]
0-200 Hz
0
Enter the motor speed to be attained as a
start signal for commencement of PI control.
20-93 PI Proportional Gain
0-10
0.01
Enter the process controller proportional gain.
Quick control is obtained at high amplifi-
cation. However if amplification is too great,
the process may become unstable.
20-94 PI Integral Time
0.1-999.0 s
999.0 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.
