Process Control Overview
6.6.11.1
The process controller enables maintaining process parameters such as temperature, pressure, and flow within a specified range or at a
desired value. This is achieved by controlling the output frequency of the drive based on continuous measurement of the actual value of
the process parameter (feedback) and the comparison of the process parameter with a setpoint.
