3.4.6 Process PID Control
The process PID control can be used to control application parameters that can be measured by different sensors (pressure,
temperature, and flow) and be affected by the connected motor through a pump or fan.
Table 3.9 shows the control configurations where the process control is possible. When a flux vector motor control principle
is used, the speed control PID parameters should also be tuned. Refer to chapter 3.2.2 Control Structure in VVC

NOTICE!
The process control PID works 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 particularly dependent on
proper speed control PID tuning to yield their full potential. The speed control PID tuning occurs before tuning the
process control PID.
