Remarks:
1. Do not use strong force to rotate the front and rear adjusting ring to avoid damage to the gear box. All operations need to be driven by the driver board!
2. Supplier changes, motor wire color and pin definition change, but the actual output direction does not change, the customer does not have to change the program.
3. The color of the wire is for reference only. Actual motor rotation shall prevail.
