Introduction: The upgraded version of TB6600 is a driver suitable for 57/42 type two-phase hybrid stepping motor with phase current 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, Such as: engraving machine, marking machine, cutting machine, laser-phototypesetting, plotter, machine tool, crystal grinding machine, automatic assembly equipment, etc. The best application object is 57 stepper motors and 42 stepper motors with a of 1.8N.m and . 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 flow to reduce heat generation. Motor noise optimization function. Small size, save space Frequently Asked Questions: 1. Question: How can I started as as possible when using this stepper driver for the first time? Answer: After the power supply and the motor are correctly connected, only the 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 , test the acceleration (increasing frequency), direction, subdivision and offline functions in turn. Question: Is it necessary to series resistance if the control signal is higher than 5V? Answer: The upgraded TB6600 does not need to series resistance. Question: The power indicator light is on after wiring, the motor does not rotate. What is the reason? Answer: If the wiring is , still does not turn, it means that 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. that the control interface has a 5mA drive capability. Question: How to the definition of the four lines of a ? Answer: Connect any two wires of the motor . At this time, there is resistance when twisting the motor 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-. Q: The forward and reverse rotation of the motor is opposite to what should be actually achieved? Answer: It is only necessary to interchange the two wires of one phase of the motor.
