Process PID Control

"
The Process PID Control can be used to control application parameters that can be measured by a sensor (i.e.
pressure, temperature, flow) and affected by the connected motor through a pump, fan or otherwise.
The table shows the control configurations where Process Control is possible. When a Flux Vector
motor control principle is used, take care also to tune the Speed Control PID parameters. Refer to
the section about the Control Structure to see where the Speed Control is active.

Note: The Process Control PID will work under the default parameter setting, but tuning the
parameters is highly recommended to optimize the application control performance. The two
Flux motor control principles are specially dependent on proper Speed Control PID tuning (prior
to tuning the Process Control PID) to yield their full potential.
