Stepper Motor Driver TB6600 Upgrade Nema 23 Nema17 4A DC9-42V For NEMA23 Motor CNC Router Controller For 3D Printer (1Pcs)

About this product

*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 peak current 4.0A ? H-bridge bipolar constant current drive ? Input signal high-speed optocoupler isolation ? Built-in temperature protection and overcurrent protection ? Automatic half flow to reduce heat generation ? Motor noise optimization function ? Small size, save space

*The power indicator light is on after wiring, but the motor does not rotate. What is the reason? Answer: If the wiring is correct, but still does not turn, it means that the drive capacity of the control part is not enough.This situation mostly occurs in the direct control mode of the io port of the single-chip microcomputer. Please ensure that the control interface has a 5mA drive capability

*How to judge the definition of the four lines of a stepper motor? Answer: Connect any two wires of the motor together. At this time,there is resistance when twisting the motor rotor by hand. Then the two lines are the same phase and can be connected to the driver A+, A-;There is still resistance when the other two lines are short-circuited, so connect these two lines to B+ and B-.
