Introduction: The upgraded version of TB6600 is a driver suitable for 57/42 type two-phase hybrid stepping motor with phase current below 4.0A. Set 7 kinds of subdivisions (1/2A/2B/4/8/16/32) through 6-bit DIP switch. And 8 gear output current (0.5A/1.0A/1.5A/2.0A/2.5A/2.8A/3.0A/3.5A) Widely used in various small and medium-sized automation equipment and hardware, Frequently Asked Questions: 1. Question: How can I get started as soon as possible when using this stepper driver for the first time? Product features: DC 9-42V power supply, 12-30V power supply is the best. The control signal input voltage is 3.3-24V universal (no string resistance required). Subdivision accuracy 1-32 subdivision optional. Output current 4.0A. H-bridge bipolar constant current drive. Input signal high-speed optocoupler isolation. Built-in temperature protection and overcurrent protection. Automatic half to reduce heat generation. Motor noise optimization function. Small size, save space Such as: engraving machine, marking machine, cutting machine, laser-phototypesetting, plotter, CNC machine tool, crystal grinding machine, automatic assembly equipment, etc. The best application object is 57 stepper motors and 42 stepper motors with a torque of 1.8N.m and below. Answer: After the power supply and the motor are correctly connected, only the pulse signal PUL is connected (first set the frequency to within 1K), the subdivision is set to 16, the direction and offline are suspended, and the motor defaults to forward after power on. After the operation is correct, test the acceleration (increasing frequency), direction, subdivision and offline functions in turn., Manufacturer: Aundhegrtt
