in some applications, and PA.08 is used to determine the reverse
rotation frequency upper limit.
devi a tion
Setti n g Range
PA. 0 9
If the deviation between PID feedback and PIO setting is smaller
than the value of PA.09,PID control stops. The small deviation
between PID feedback and PID setting will make the output
frequency stable and unchanging, especially effective for some
closed-loop control applications.
PIO di ffe renti a l
Seili n g Range
PA.10
It is used to set the PID differential output range. In PID control, the
differential operation may easily cause system oscillation. Thus, the
PID differential regulation is restricted to a small range. PA.1 0 is
set
used to the range of PID differential output.
Setti n g Range
The PIO setting changing time indicates the time required for PIO
setting changing from 0.0% to 100.0%. The PIO setting changes
linear1y according to the changing time, reducing the impact caused
by sudden setting change on the system.

PA. 1 2 is used to filter the PID feedback, helping to reduce
interference on the feedback but slowing down the response of 1he
process closed-loop system.
PA.13 is used lo fllter !he PID output frequency, helping
sudden change of the AC drive output frequency but slowing down
the response of the process closed-loop system.
