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