PID gain simple setting:
1.
After changing target, response is slow ---Increase P-gain (K
P
=08-04(
P.172
))
response is quick but unstable ---Decrease P-gain (K
P
=08-04(
P.172
))

K

is too large

2. Target and feedback have deviation ---Decrease Integration time (K
I
=08-05(

))
become equal after unstable vibration ---Increase Integration time (K

Even after increasing K
P
, response is still slow ---Increase D-gain (K
D
=08-06)
It is still unstable ---Decrease D-gain (K
D
=08-06)
Note: 1. When 08-09(
P.177
)=2, keypad will not show alarm but digital output terminal will send signal. This signal can
be turned off through 00-02=2(P.997=1)reset or power off.
2. When setting target source and feedback source, please pay attention to 08-00(
P.170
) and
02-00
(P.500)
~02-02(P.504) setting.
