6.2.7 Process PID Main Frequency Setting
Process PID control is a common method of process control. Through proportional,
integral and differential calculation of the difference between the feedback signal and the
target signal of the controlled variable, the output frequency of the inverter is adjusted by
the closed-loop, so that the controlled variable can be stabilized at the target value
;
When the PID is used as reference, if the PID forbidden is set at the same time
(terminal function 44), the system will switch to the F9.29 standby channel for regulation.
