N O T E :
Brushless motors are commutated electronically by the controller. The use of Hall effect devices
for commutation is recommended.
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. Refer to
for powered motor phasing or
for unpowered motor and
feedback phasing.
N O T E :
If using standard Aerotech motors and cables, motor and encoder connection adjustments are
not required.
