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 (
). 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.

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