N O T E : Brushless motors are commutated electronically by the controller. The use of Hall effect devices
for commutation is recommended.
The drive 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.
There are two methods for verifying motor connections: powered, through the use of a test program; and an
unpowered method using an oscilloscope. Both methods will identify the A, B, and C Hall/motor lead sets
and indicate the correct connections to the drive.
N O T E : If using standard Aerotech motors and cables, motor and encoder connection adjustments are
not required.
