2.2.3. Stepper Motor Connections
The configuration shown in Figure 2-9 is an example of a typical stepper motor connection. Refer to
Section 2.2.3.1. for information on motor phasing.
In this case, the effective motor voltage is half of the applied bus voltage. For example, an 80V motor
bus supply is needed to get 40V across the motor.

2.2.3.1. Stepper Motor Phasing
A stepper motor can be run with or without an encoder.
Without an Encoder:
You do not need to phase the motor.
With an Encoder:
Because the end of travel (EOT) limit inputs are relative to motor rotation,
it is important to phase the motor.
Run a positive motion command. The motor is phased correctly if there is a positive scaling factor
(determined by the CountsPerUnit parameters) and the motor moves in a clockwise direction when you
view the motor from the front mounting flange (
Figure 2-10 ). If the motor moves in a counterclockwise
direction, swap the motor leads and re-run the command. After the motor has been phased, if you want
to change the direction of positive motion, use the ReverseMotionDirection parameter.
Figure 2-10: Positive Motor Direction
For Aerotech-supplied systems, the motor, encoder and Hall sensors are correctly configured and
connection adjustments are not necessary.
