Installation, Wiring, and Setup Tips

• Always disconnect power before wiring. Verify motor coil wiring (A+/A-, B+/B-) to avoid damage.
• Set the microstepping and current limit via the on-board jumpers and potentiometer according to your motor datasheet.
• Use a sufficiently rated power supply in the 10 to 35 V DC range; higher voltages improve high-speed torque but increase heat.
• Ensure adequate cooling and ventilation. Use heatsinks and consider active cooling for sustained high current operation.
• Keep signal wiring short and twisted where possible to reduce noise; use the optical isolation features for improved reliability.

Microstepping and Current Adjustment

Microstepping reduces vibration and improves motion resolution. Choose full step for maximum torque, or 1/8 and 1/16 for smoother, higher-resolution moves. Adjust the driver current to match the motor’s rated current while leaving headroom for safe operation. Lowering current reduces heat but also reduces torque.

Protection and Reliability

The TB6560 driver includes over-current, under-voltage, and thermal shutdown protections to guard against common fault conditions. Optical isolation on the inputs helps prevent ground loops and noise from affecting control electronics. These features make the driver suitable for both hobby and industrial-style projects.

Compatibility and Integration

The TB6560 Stepper Motor Driver 3A works well with common motion controllers, Arduino-based systems, GRBL-based CNC controllers, and other step/dir control boards. Its compact footprint and standard pinout make it simple to mount on machine frames or inside control enclosures.
