Appendix: Process PID control

What this chapter contains

The chapter contains instructions on quick configuration of the process control, gives
an application example and describes the PID sleep functionality.

Process PID control

There is a built-in PID controller in the drive. The controller can be used to control
process variables such as pressure, flow or fluid level. In process PID control, a
process reference (setpoint) is set with drive's integrated potentiometer. An actual
value (process feedback) is connected to the drive's analog input. The process PID
control adjusts the drive speed in order to keep the measured process quantity
(actual value) at the desired level (setpoint).
