Subchart A1: Simple Motor Setup with Energy Savings or Speed Search Using V/f
Mode
Figure 4.7, Flowchart A1, describes simple motor setup for V/f control. V/f Motor Control is suited for the most basic
applications such as fans or pumps. This procedure
illustrates using Energy Savings and Speed Estimation Speed Search.
V/f control can be used where rotational auto-tuning cannot be performed.
