PARAMETER DESCRIPTION 232
5.9.6 PID integral property

PID integral separation function can effectively reduce overshoot.

Set the deviation between target and feedback when
integral separate function works.
PID
integral separated function

When set 08-28(P.715) to 1, integral separation is on. If deviation between target and feedback is greater than
08-29(P.716) value, PID will only perform proportional and differential controller, which can reduce the overshoot
of PID.
5.9.7 PID differential limit

In PID control, differential controller can cause system to oscillate, so generally differential needs to be limited to a
very small range.
Parameter Name Default Setting Range Content
08-30
P.717
PID differential limit 0.10% 0～100.00% Set PID differential limit
PID differential limit

In PID control, differential controller is sensitive and may easily cause system oscillation. Generally differential is
set to a small range. 08-30(P.717) is used to set PID differential output range.
5.9.8 PID output deviation limit

PID output deviation limit can control the change of PID output and improve the stability of inverter operation
Parameter Name Default Setting Range Content
08-31
P.718 PID output positive
deviation limit
100.00% 0～100.00%
Set the limit for PID two outputs
08-32
P.719 PID output negative
deviation limit
100.00% 0～100.00%
PID output deviation limit

This function is used to limit the difference between two outputs of PID, which can effectively prevent PID output
from changing too fast and stabilize inverter operation.
