Brushless Motor Phasing
Brushless motors are commutated electronically by the controller, typically using Hall-effect devices. If you
are using standard Aerotech motors and cables, motor phasing adjustments are not required and this section
may be skipped.
The controller requires that the Back-EMF of each motor phase be aligned with the corresponding Hall-effect
signal. To ensure proper alignment, motor, Hall, and encoder connections should be verified using one of the
following methods: powered, through the use of a test program; or unpowered using an oscilloscope. Both
methods will identify the A, B, and C Hall/motor lead sets and indicate the correct connections to the
controller.
