10 PID Control Parameters
PID control is a common method of process control. By performing proportional, integral, and differential
operations on the difference between the controlled variable feedback signal and the target signal, and by
adjusting the output frequency of the inverter, a closed-loop system is formed to stabilize the controlled variable at
Target value. It is suitable for process control occasions such as flow control, pressure control and temperature
control. Figure 5-25 shows the principle block diagram of the process PID control.

This parameter is used to select the given channel for the target quantity of the process PID.
The process PID setting target value is a relative value, and the setting range is 0.0%~100.0%. Similarly, the
feedback quantity of PID is also a relative quantity. The role of PID is to make these two relative quantities the
same.
