Enter the feedback value that corresponds to the voltage or
current set in parameter 6-21 Terminal 54 High Voltage/pa-
rameter 6-23 Terminal 54 High Current.
Enter the filter time constant.
0.01
Select if terminal 54 is used for current or voltage input.
[1] Voltage
[0] Normal
Select [0] Normal to set the process control to increase the
output speed when the process error is positive. Select [1] In-
verse to reduce the output speed.
Enter the motor speed to be attained as a start signal for
0 Hz
commencement of PI control.
0.01
Enter the process controller proportional gain. Quick control
is obtained at high amplification. However, if amplification is
too high, the process may become unstable.
Enter the process controller integral time. Obtain quick con-
999.0 s
trol 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.
