6.20 Special operation
6.20.1 PID control (Pr. 127 to Pr. 134)
The inverter can be used to exercise process control, e.g. flow rate, air volume or pressure.
The terminal 2 input signal or parameter setting is used as a set point and the terminal 4 input signal
used as a feedback value to constitute a feedback system for PID control.
