4-7-3 Pole position detection method setting
There are three ways to detect the motor's pole position: CS signal-using method (CS signal), automatic estimation
method of pole position without using CS signal (Pole position estimation), and stored position-using method (Pole
position recovery).
4-7-3-1 CS signal method
Detect a pole position by using the CS signals (CS1, CS2, CS3).
This section describes how to manually set the direction and phase of CS signal.
For information on the automatic setting with a tool, refer to the “Section 4-7-4”.
