4.3.4 Improved Control
Using a drive to control the ow or pressure of a system improves control. A drive can vary the speed of the fan or pump, obtaining
variable control of ow and pressure. Furthermore, a drive can quickly adapt the speed of the fan or pump to new ow or pressure
conditions in the system.
Obtain simple control of process (ow, level, or pressure) using the built-in PI control.
