F6-05 PID setting feedback range 0–65535 1000
This parameter is a non-dimensional unit. It is used for PID setting display and PID feedback
display.
If this parameter is set to 1000, PID setting and PID feedback 0% to 100.0% corresponds to
0 to 1000 in linear mode.

It decides the regulating intensity of the PID regulator. The higher the Kp1 is, the larger
the regulating intensity is. The value 100.0 indicates when the deviation between PID
feedback and PID setting is 100.0%, the adjustment amplitude of the PID regulator on

It decides the integral regulating intensity. The shorter the integral time is, the larger
the regulating intensity is. When the deviation between PID feedback and PID setting
is 100.0%, the integral regulator performs continuous adjustment for the time set in F6-

It decides the regulating intensity of the PID regulator on the deviation change. The
longer the differential time is, the larger the regulating intensity is. Differential time is the
time within which the feedback value change reaches 100.0%, and then the adjustment

F6-09 PID deviation limit 0.0%–100.0% 0.0%
If the deviation between PID feedback and PID setting is smaller than the value of F6-09,
PID control stops. The small deviation between PID feedback and PID setting will make the
