PID control (Pr. 127 to Pr. 134, Pr. 575 to Pr. 577)
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.
Purpose
Parameters that must be set
Refer to
Section
