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 such as the MFM10 can be installed between the drive and the motor, which
will reduce the level of PWM amplifier related current spikes in the system.
