When the deviation between the PID set amount and the feedback amount is less than
PA-09, the PID stops the adjustment operation. In this way, the output frequency is stable
when the deviation between the given feedback and the feedback is small, which is
effective for some closed-loop control

PID regulator, the role of differential is more sensitive, it is easy to cause the system
oscillation, for which the PID differential is generally limited to a smaller range, PA-10 is
used to set the PID differential output range.

PID given change time, that PID set value from 0.0% to 100.0% of the time required.
When the PID reference changes, the PID setpoint changes linearly according to the given
change time, reducing the adverse effect of a given mutation on the system.

PA-12 is used to filter the PID feedback, which helps to reduce the effect of the amount
of feedback on the feedback, but will bring the response performance of the closed-loop
system.
PA-13 is used to filter the frequency of the PID output, which will reduce the frequency
of the inverter output frequency, but also will bring the response performance of the
closed-loop system.
