3. Setup and Wiring

Proper wiring and configuration are crucial for the correct operation of the stepper motor driver. Ensure all connections are secure before applying power.

3.1. Interface Description

The driver features several input and output interfaces:

• PUL+ / PUL-: Step Pulse signal input.
• DIR+ / DIR-: Motor Direction control Signal input.
• EN+ / EN-: Motor Enable signal input.
• A+ / A-: Connects to motor winding phase A.
• B+ / B-: Connection to motor winding phase B.
• VCC / GND: Power supply input (9-42V DC).

The ENA (Enable) terminal can be left unconnected. When ENA is activated, the motor rotor is free (offline), allowing manual rotation of the motor shaft for adjustment. After adjustment, set ENA to the inactive state for automatic control.

3.2. Control Signal Wiring

The input signals (Pulse, Direction, Enable) can be connected using either common anode or common cathode methods. The external signal (3.3-24V) can be connected directly without a series resistor.

Figure 4: Common Anode connection diagram. This method uses active low signals.

Figure 5: Common Cathode connection diagram. This method uses active high signals.

3.3. Motor Wiring

The TB6600 driver is compatible with 4, 6, and 8-wire 2-phase/4-phase hybrid stepper motors. Refer to your motor's specifications for correct winding identification. Connect motor windings A and B to the corresponding A+/A- and B+/B- terminals on the driver.

3.4. DIP Switch Settings

The TB6600 driver features DIP switches for setting the microstep subdivision and output current. It is recommended to adjust these settings when the power is off.

3.4.1. Microstep Subdivision Setting (SW1-SW3)

Switches SW1, SW2, and SW3 control the microstep resolution. The subdivision determines the number of pulses per revolution for the motor. The stepping motor pitch angle after subdivision is calculated as: Motor inherent step angle / subdivision number.

Figure 7: Table for setting microstep subdivision using DIP switches SW1, SW2, and SW3.

3.4.2. Current Setting (SW4-SW6)

Switches SW4, SW5, and SW6 control the output current to the motor. Set the current according to your stepper motor's rated current to prevent overheating or underperformance.

4. Operating Instructions

Once the driver is correctly wired and configured, it is ready for operation. The driver receives pulse and direction signals from a controller (e.g., microcontroller, CNC board) to move the stepper motor.

• Pulse Signal (PUL): Each pulse received by the driver causes the motor to move one step (or microstep, depending on subdivision settings).
• Direction Signal (DIR): The state of this signal determines the rotation direction of the motor.
• Enable Signal (EN): When active, the motor is energized and holds its position. When inactive, the motor is de-energized and can be freely rotated.

Ensure your control system provides clean, stable pulse and direction signals within the specified voltage range (3.3-24V).

5. Maintenance

The TB6600 stepper motor driver is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:

• Environmental Conditions: Operate the driver within its specified temperature and humidity ranges. Avoid dusty or corrosive environments.
• Heat Dissipation: Ensure adequate airflow around the driver, especially around the heatsink fins, to prevent overheating. Do not obstruct the heatsink.
• Connections: Periodically check all wiring connections for tightness and signs of wear or corrosion. Loose connections can lead to erratic behavior or damage.
• Cleaning: If necessary, gently clean the driver with a soft, dry cloth. Do not use liquid cleaners or solvents.

6. Troubleshooting

If you encounter issues with your TB6600 stepper motor driver, consider the following troubleshooting steps:

• Motor Not Moving:
  • Verify power supply voltage is within 9-42V DC and correctly polarized.
  • Check motor wiring for correct phase connections (A+/A-, B+/B-).
  • Ensure pulse (PUL) and direction (DIR) signals are being sent from the controller.
  • Confirm the Enable (EN) signal is active (motor not in offline state).
  • Check DIP switch settings for current and subdivision. Ensure current is sufficient for the motor.
• Erratic Motor Movement or Missed Steps:
  • Reduce the pulse frequency from the controller.
  • Check for electrical noise on signal lines. Use shielded cables if necessary.
  • Ensure motor current is set correctly; too low current can cause missed steps.
  • Verify mechanical load on the motor is not excessive.
• Driver Overheating:
  • Ensure adequate ventilation and airflow around the heatsink.
  • Check if the output current setting (DIP switches SW4-SW6) is too high for the motor.
  • Verify the input voltage is not exceeding 42V.
• Motor Vibrates but Does Not Rotate:
  • Incorrect motor phase wiring. Double-check A+/A- and B+/B- connections.
  • Insufficient current setting.

7. Safety Warnings

Observe the following safety precautions during installation and operation:

• Always disconnect power before making or changing any wiring connections.
• Ensure proper grounding for the power supply and system components.
• Do not exceed the maximum input voltage of 42V DC.
• Avoid touching the driver's heatsink during operation, as it may become hot.
• Protect the driver from moisture, dust, and conductive debris.
