PG feedback parameter group 09
PARAMETER DESCRIPTION 196
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.

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.

 This function is used to limit the deviation between two PID outputs to suppress the rapid change of PID output and stabilize the
running of the inverter.
