PID gain simple setting:
1. After changing target, response is slow ---Increase P-gain (K
P
=08-04)
response is quick but unstable ---Decrease P-gain (K
P
=08-04)
When K
P
is too small When K
P
is too large
When K
P
is appropriate
2. Target and feedback have deviation ---Decrease Integration time (K
I
=08-05)
become equal after unstable vibration ---Increase Integration time (K
I
=08-05)
When K
I
is appropriate
When K
I
is too short
When K
I
is too long
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)
02-01(P.501) setting
