Parameter 6-25
Terminal 54
High Ref./
Feedb. Value
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.
Parameter 6-26
Terminal 54 Fil-
ter Time Con-
stant
Enter the filter time constant.
Parameter 6-29
Terminal 54
mode
Select if terminal 54 is used for current or voltage input.
Parameter
20-81 PI Nor-
mal/Inverse
Control
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.
Parameter
20-83 PI Start
Speed [Hz]
Enter the motor speed to be attained as a start signal for
commencement of PI control.
Parameter
20-93 PI Propor-
tional Gain
Enter the process controller proportional gain. Quick control
is obtained at high amplification. However, if amplification is
too high, the process may become unstable.
Parameter
20-94 PI Inte-
gral Time
Enter the process controller integral time. Obtain quick con-
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.
