 Subchart A-1: Simple Motor Setup Using V/f Control
Flowchart A-1 in Figure 4.9 describes simple motor setup for V/f Control, with or without PG feedback. V/f Control is
suited for more basic applications such
as fans and pumps. This procedure illustrates Energy Savings and Speed
Estimation Speed Search.
