2.7.3 Stepper Motor Connections

When you connect a stepper motor that is an Aerotech motor with Aerotech cabling, no
motor phasing process is required.
Note the connection of the two motor phases

2.7.3.1 Stepper Motor Phasing Process

A stepper motor is phased correctly when a positive motion command causes the motor to
rotate in a CW direction, assuming a positive scaling factor, as determined by the
PosScaleFactor parameter. To correct the phasing, reverse the connections to the A and
B terminals on the Soloist. This is important because the inputs for the end of travel
(EOT) limit are determined by motor rotation. After correctly phasing the motor, you can
reverse the motor direction when commanding a positive move from a user task by
changing the PosScaleFactor parameter to a negative value.
