2.2.1. Brushless Motor Connections
The configuration in
shows a typical brushless motor connection.
For optimum performance:
l
Aerotech recommends that you use shield cables designed for VFD applications.
l
Series inductance could be required when you use long cables ( > 20 m) to prevent high voltage
ringing.
o
This should be added to each motor phase close to the drive.
o
Application dependent.
l
The cable voltage and current rating must be sized according to the application requirements and
local electrical safety regulations.
l
The drive parameters AverageCurrentThreshold and AverageCurrentTime must be set to protect
the motor from overheating.

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.
For Aerotech-supplied systems, the motor, encoder and Hall sensors are correctly configured and
connection adjustments are not necessary.
