DMC-3425 Chapter 1 Overview• 3
The DMC-3415 can control BLMs equipped with Hall sensors as well as without Hall sensors. If hall
sensors are available, once the controller has been setup, the controller will estimate the commutation
phase upon reset. This allows the motor to function immediately upon power up. The Hall effect
sensors also provide a method for setting the precise commutation phase. Chapter 2 describes the
proper connection and procedure for using sinusoidal commutation of brushless motors.
* 6 Milliseconds per magnetic cycle assumes a servo update of 1 msec (default rate).
