Section V Parameter Function Table

Section V
little, the response will lag.
P08
PID sampling period
0.002~10.000
s
0.010
Y
Set Sampling period of feedback signal.
When set this parameter small, the system response speed to the giving and feedback
deviation is slow, but control is stable.
When set this parameter low,the system response speed to the giving and feedback deviation
is slow, but easy to cause vibration
P09
Deviation limit
0.0~20.0
%
5.0
Y
Deviation limit effects system control accuracy and stability.
When the deviation of feedback signal and giving signal <deviation limit, PID N regulation,
keep output stable.
When the deviation of feedback singnal and giving signal >deviation limit, PID regulates
according to deviation, update output
P10
PID fault detect time
0.0~3200.0
s
0.0
N
P11
PID fault detected value
0.0~100.0
%
10.0
N
Set P10 to 0. 0 for N fault inspection.
When PID feedback signal <P11 set PID fault inspection value, last P10set time, regard it as
PID regulation fault.
P12
PID display range
0.00~100.00
-
1.00
Y
A09 PID set value＝PID set value(%)*P12
A10 PID feedback value＝PID feedback value(%)*P12
If PID feedback 10V corresponding 4.0Mpa pressure, if need A09, A10 to display actual
value, only need to set P12 = 0.04.
