◆ 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. This procedure illustrates using Energy Savings
and Speed Estimation Speed Search. V/f control can be used where rotational auto-tuning cannot be performed.

◆ Subchart A2: High Performance Operation Using Open Loop Vector Motor Control

Figure 4.8, Flowchart A2, describes Open Loop Vector Control for high-performance motor operation. This is
appropriate for applications requiring high starting torque, torque limits, and improved speed regulation.
