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.
