Working Principles

The TB6560AHQ operates by receiving control signals from a microcontroller or other control circuitry. These control signals determine the motor rotation direction, step size, and enable/disable status. Based on these inputs, the internal logic circuitry generates appropriate drive signals for the motor windings
