• The upgraded version of TB6600 driver is a 57/42 type hybrid stepping motor suitable for phase current below 4.0A

• Set 7 subdivisions (1/2A/2B/4/8/16/32) by 6-bit DIP switch

• And 8 output currents (0.5A/1.0A/1.5A/2.0A/2.5A/2.8A/3.0A/3.5A)

• Widely used in engraving machines, marking machines, cutting machines, laser imagesetters, plotters, CNC machine tools, crystal grinders, automatic assembly equipment, etc.

• The best application objects are 57 stepper motors and 42 stepper motors with a torque of 1.8Nm and below

Specifications:

• Power supply: DC 9-42V, 12-30V (best)

• Voltage input: 3.3-24V

• Subdivision precision: 1-32

• Output peak current: 4.0A

• H-bridge bipolar constant current drive.

• Automatic half-flow reduces heat generation and low noise. Small size and space-saving.

Frequently Asked Questions:

• 1. Q: How to use it for the first time?

• Answer: After the power supply and the motor are correctly connected,

• Only connect the pulse signal PUL (first adjust the frequency to within 1K);

• The subdivision is set to 16, the direction and offline are suspended, and the motor defaults to forward rotation after power-on. After the operation is correct, test the acceleration (increase the frequency);

• Orientation, segmentation, and offline functionality work in sequence.

• 2. Q: Does the control signal need a series resistance if the control signal is higher than 5V?

• Answer: The upgraded TB6600 does not need to increase the series resistance.

• 3. Question: After wiring, the power indicator light is on, but the motor does not rotate?

• Answer: If the wiring is correct, but it still does not turn, it means that the driving capacity of the control part is not enough.

• This situation mostly occurs in the direct control mode of the IO port of the microcontroller.

• Make sure the control interface has a 5mA drive capability.

• 4. Q: How do you judge the definition of four wires of 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 these two lines are in phase and can be connected to the driver A+, A-;

• There is still resistance when the other two wires are shortened, so connect these two wires to B+ and B-.

• 5. Q: The forward and reverse directions of the motor are opposite?

• Answer: Just swap the two wires of one phase of the motor.
