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
Section 2.2.1.1. for powered motor phasing or Section 2.2.1.2. for unpowered motor and
feedback phasing.
For Aerotech-supplied systems, the motor, encoder and Hall sensors are correctly configured and
connection adjustments are not necessary.
A motor filter module can be installed between the drive and the motor to reduce the effects on
PWM generated noise currents.
