 PID process adopts normalized input and output, that is, both the input and output range are between
-100%~+100%. The input scaling is related to feedback channel, sensor characteristics and analog input
setting. The output scaling takes the maximum frequency as 100% for frequency control.
There is a filtering section for the PID reference channel and feedback channel, for example, the filtering
time for AI1 is F6-03. These filtering sections have influence on the control performance and can be set
according to the actual needs.
 In some machines (such as centrifuges), the square root of the inlet pressure has a linear relationship with
the flowrate, therefore, the square root feedback can be used to control the flowrate.
 F7-03 is used to scale FU-13 and FU-14, making them match the real physical units. It has no influence
on the control.

 Hope800 has two sets of PID parameters: PID parameter 1(F7-05, F7-06, F7-07) and PID parameter
2(F7-08, F7-09, F7-10). They can be switched mutually by the digital input 36. They can also be
