PA-03
PID feedback filter time
0.00s~30.00s
PA-04
PID output filter time
0.00s~30.00s
PA-03 is used to filter the PID feedback, which is helpful to reduce the influence of the disturbance on the
feedback, but it will lead to the degradation of the response performance of the process closed-loop system.
PA-04 is used to filter the PID output frequency, which will weaken the mutation of the inverter output
frequency, but it will also lead to the degradation of the response performance of the process closed-loop
system.

PID setting change time
0.00s~300.00s
The given change time of PID refers to the time required for the given value of PID to change from 0.0% to
100.0%.
When the given value of PID changes, the given value of PID changes linearly according to the given change
time to reduce the adverse impact of the given mutation on the system.

PA-07
PID reverse cut off frequency
0.00Hz~max output frequency
In some cases, only when the PID output frequency is negative (i.e. inverter reversal), PID can control the
quantitative and feedback quantity to the same state, but the high reverse frequency is not allowed for some
occasions, and PA-07 is used to determine the upper limit of reverse frequency.
When the frequency source is PID, the frequency output range is as follows:
For example: frequency source is pure PID or main + PID
(1) The reverse cutoff frequency is 0 (PA-07=0) or reverse is forbidden (P0-21=1). Output range: lower
frequency to upper frequency (i.e. P0-17~P0-15).
(2) The reverse cut off frequency is not 0 and reverse running is not prohibited (PA-07≠0, P0-21=0). Output
range: - reverse cut off frequency ~ upper limit frequency.

PA-08
PID deviation limit
0.0%~100.0%
When the deviation between the given quantity and the feedback quantity of PID is less than PA-08, the PID
stops adjusting. In this way, the output frequency is stable when the deviation between given and feedback is
small, which is very effective for some closed-loop control situations.

PA-09
PID differential limiting
0.00%~100.00%
In PID regulator, the function of differential is sensitive and easy to cause system oscillation. Therefore, the
function of PID differential is generally limited to a small range. PA-09 is used to set the output range of PID
