How to control the rotation direction of stepper motor?

Step motor rotation direction change, can change the control system direction level signal.

Step motor rotation direction change two, you can adjust the motor wiring to change the direction, the specific approach is as follows:

For A two-phase motor, simply switch the motor line of one phase into A stepper motor driver, such as A+ and A- switch.

Special attention should be paid to changing the rotation direction of the stepper motor. For the three-phase motor, the motor line of one phase should not be exchanged, but the two phases should be exchanged sequentially, such as A+ and B+ exchange, A- and B- exchange.
