6.10 PID control (F09 group)
PID control is a common method used in process control, such as flow, pressure
and temperature control. The principle will firstly detect the bias between preset
value and feedback value, then calculate output frequency of the system
according to proportional gain, integral and differential time. Please refer to
following figure:
Figure 6-14 PID control
In the system, the PID control is valid only when the X frequency source
reference selection (F0.04) or the Y frequency source reference selection (F0.05)
