How to control the direction of the stepper motor

1, can change the direction of the control system level signal. 2, the wiring of the motor can be adjusted to change direction, specific practices are as follows: for the two-phase motor, just put the one line exchange access phase motor drives, such as A + and A -Exchange. For three-phase motor, the adjacent two phase motor line exchange, such as: A, B, C three-phase, exchange A, B two phase.
