Example 02: PID positive feedback
 Pr.08-10 must < Pr.08-11
 30kg is the reference
 Set the parameter:
Pr.03-00 = 5 (AVI is PID feedback)
Pr.08-00 = 4 (PID
positive feedback: AVI
simulation input function select)
Pr.08-10 = 110% (Sleep reference:
33kg = 110%*30kg)
Pr.08-11 = 120% (Wake-up reference:
36kg = 120%*30kg)
Case 01: If feedback <33kg, frequency decreases.
Case 02: If feedback >36kg, frequency increases.
