TB6600 Stepper Motor Driver - The TB6600 driver is designed for small and medium automation equipment such as engraving machines, marking machines, cutting machines, plotters, CNC machine tools and holding equipment. It can drive 4, 6 or 8 wire two-phase, four-phase stepper motors. - Isolated optocoupler signal input provides strong anti-interference capability, delivering stable and reliable performance even in noisy environments. - Built-in protection functions: overheating protection, over-current protection, undervoltage lockout, and input voltage reverse connection protection. These features enhance safety and durability. - Compact in size and easy to integrate into different systems. The interface uses high-speed optocoupler insulation, and the current can be set with a dip switch. No external series resistor is required for the external 3-24V signal. - Practical use scenarios: - Desktop engraving or marking machines for small-to-medium production runs. - Compact CNC router, milling machine, or cutting plotter in workshop or education settings. - General automation equipment requiring reliable stepper motor control and compact drive integration.
