FA-08
PID reverse cut-off frequency
limit
Default value
2.00Hz
Set range
0.00
～
maximum frequency
In some cases, only when the output frequency of PID is negative (ie, the frequency converter is reversed),
can it make the given value the same with the feedback value. But excessive reverse frequency is not
permitted in some circumstances and it is limited by FA-08.
FA-09
Diviation limit
Default value
0.0%
Set range
0. 0%
～
100.0%
When deviation between the given value and the feedback value of PID is less than FA-09, the adjusting
operation of PID stops, so that the output frequency can remain stable when deviation between the two
values is relatively small, which can be very efficient in some Closed-loop control occasions.
FA-10
Derivative limiting
Default value
0.10%
Set range
0
．
00%
～
100.00%
Differential plays a sensitive role in PID regulator, which can easily leads to system oscillation, so it is
usually restricted in a small realm with the output range set by FA-10
.
FA-11
PID given changing time
Default value
0.00s
Set range
0.00s
～
650.00s
PID given changing time is the time needed for PID given value to change from 0.0% to 100.0%
.
When given PID changes, the given value takes on a linear change in accordance with the given time, thus
reducing the negative effects it might has on the system.
FA-12
PID feedback filter time
Default value
0.00s
Set range
0.00s
～
60.00s
FA-13
PID output filter time
Default value
0.00s
Set range
0.00s
～
60.00s
FA-12 is use to filter PID feedback quantity, which can reduce the chance of feedback quantity being
disturbed but may weaken the response performance of the process closed-loop system.
FA-13 is used to filter PID output frequency, which may reduce the sudden change of the output frequency
of the converter, but may also weaken the response performance of the process closed-loop system
FA-15
Proportional gain Kp2
Default value
20.0
Set range
