2.5.2 Process PID Control
The process PID control can be used to control application parameters that can be measured by a sensor (for example
pressure, temperature, ow) and aected by the connected motor through a pump, fan, or other connected devices.
Table 2.8 shows the control congurations in which the process control is possible. Refer to chapter 2.3 Control Structures to
see where the speed control is active.

NOTICE
The process control PID works under the default parameter setting, but tuning the parameters is recommended to
optimize the application control performance.
