100%.
If relative error of close loop system is bigger than the setting value of error
limit, then the PID regulator will adjust the error.
If relative error of close loop system is in the setting range of error limit, then
stop PID regulating, PID regulator's output maintains constant.
PA.13
Level of abnormal feedback signal
Setting range
：
0~100%
This function code defines abnormal level of feedback signal.
Definition: Abnormal level = |reference – feedback|/reference×100

PA.14
Detection
time
of
abnormal
feedback signal
Setting range
：
0~3600S
This function code defines the detection time of abnormal feedback signal.
When feedback signal exceeds abnormal level and hold time exceeds the detection
time, action at abnormal signal (ER.06) will be executed. When this parameter is set
to 0, the abnormal feedback signal detect function is disable.

0:
No sleep function;

Internal waking up, which is controlled by parameters PA.17~PA.20;
2.
External input terminal, which is controlled by terminal function 26 (PID
waking terminal), is decided by parameter P6.02~P6.08.
