Sampling period (T) : refers to the sampling period of feedback amount, the
regulator operates once each sampling period. The greater sampling period, the slower
response.
PID control deviation limit: refers to allowable deviation between PID system
output value and closed-loop setting value, as shown in figure, PID regulator stops
adjustment. The reasonable setting to this function code can adjust the accuracy and
stability of PID system.

Feedback disconnection detection value: the detected value is relative to the full scale
(100%), the system has been detecting PID feedback, when the feedback value is less
than or equal to the feedback disconnection detection value, the system starts to detect
timing. When the detection time exceeds the feedback disconnection detection time, the
system will report PID feedback disconnection fault (E.PId) .
