b. Connect each phase to the SD02B, and ignore the polarity (+/-) for now. User
has a 50% chance of guessing right.
c. Press Test button on SD02B. The stepper motor should rotate in CCW
(counterclockwise) by looking at the motor shaft. If it is in the opposite
direction, switch either phase X and !X or Y and !Y (effectively reversing
directions).
d. In case the stepper come with five coil wires, then each phase share the same
common wire.
SD02B will only drive 2 coils which are 1a to 1b and 2a to 2b. Following pictures show
typical connection from SD02B to Unipolar and Bipolar stepper motors.
Unipolar Stepper motor (6 wires)
Bipolar Stepper motor (4 wires)
