2.2.4. Three Phase Stepper Motor Connections
IMPORTANT : This feature is only supported in Automation1 software version 2.2.0. or
later.
The configuration shown in Figure 2-12 is an example of a typical three phase stepper motor
connection. Refer to Section 2.2.4.1. for information on motor phasing.

2.2.4.1. Stepper Motor Phasing
A three phase 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 ServoLoopSetup parameter) and the motor moves in a clockwise direction when
you view the motor from the front mounting flange ( Figure 2-13 ). If the motor moves in a
counterclockwise direction, reverse 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.
