value by adjusting the output frequency of the inverter. It applies to
process control situation such as flow control, pressure control and
temperature control. Process PID control functional block diagram is
as figure 5-8.

Proportional gain (Kp): it Decides the adjustment intensity of the
whole PID regulator, the bigger the Kp, the bigger the adjustment
intensity.
Integral time (Ti): Decide the deviation of PID feedback and given to
