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).

2. 4010 SET POINT SEL: Determine the source for the PID reference signal (PID
setpoint) and define its scale (4006 UNITS, 4007 UNIT SCALE).
3. 4014 FBK SEL and 4016 ACT1 INPUT: Select the process actual value
(feedback signal) for the system and configure feedback levels (4018 ACT1
MINUMUM, 4019 ACT1 MAXIMUM).
