How to Use stepper driver: Examples, Pinouts, and Specs

The TB6600 stepper driver is a widely-used electronic component designed to drive stepper motors, which are commonly used in CNC machines, 3D printers, and other precision motion control applications. The TB6600 provides an easy and efficient way to control stepper motors with high precision and reliability.

• Supply Voltage: 9V to 42V DC
• Output Current: Adjustable from 0.5A to 4.0A (peak)
• Input Signal Voltage: 3.3V to 24V (high level)
• Microstepping: Full, 1/2, 1/4, 1/8, 1/16, 1/32 selectable
• Operating Temperature: -10°C to 45°C
• Dimensions: 96mm x 71mm x 39mm

1. Power Supply: Connect a DC power supply to the VCC and GND pins, ensuring the voltage is within the specified range.
2. Motor Connection: Connect the motor coils to the A+ and A-, and B+ and B- terminals.
3. Control Signals: Connect the ENA+, DIR+, and PUL+ to the respective control signals, and ENA-, DIR-, and PUL- to the ground or negative control signals.

• Always ensure the power supply is turned off before making any connections.
• Set the current limit according to the motor's specifications to prevent damage.
• Use appropriate heat sinks if operating at high currents for extended periods.
• Microstepping settings should be configured based on the application's precision requirements.

// Define the stepper motor connections and steps per revolution
#define dirPin 2
#define stepPin 3
#define stepsPerRevolution 200

void setup() {
  // Set the motor control pins as outputs
  pinMode(dirPin, OUTPUT);
  pinMode(stepPin, OUTPUT);
}

void loop() {
  // Set the spinning direction clockwise
  digitalWrite(dirPin, HIGH);

  // Spin the motor one revolution slowly
  for (int i = 0; i < stepsPerRevolution; i++) {
    // These four lines result in 1 step:
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(2000);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(2000);
  }

  delay(1000); // Wait a second

  // Set the spinning direction counterclockwise
  digitalWrite(dirPin, LOW);

  // Spin the motor one revolution quickly
  for (int i = 0; i < stepsPerRevolution; i++) {
    // These four lines result in 1 step:
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(1000); // This delay controls the speed
    digitalWrite(stepPin, LOW);
    delayMicroseconds(1000);
  }

  delay(1000); // Wait a second
}

• Motor not moving: Check power supply, connections, and ensure the enable pin is set correctly.
• Motor stalling or skipping steps: Adjust current limit, check for mechanical obstructions, or reduce speed.
• Overheating: Ensure proper current settings and use heat sinks if necessary.

Q: Can I use the TB6600 with a 5V logic controller? A: Yes, the TB6600 is compatible with 3.3V to 24V logic levels.

Q: How do I set the current limit on the TB6600? A: The current limit is set using the onboard dip switches according to the motor's specifications.

Q: What is the maximum stepping frequency for the TB6600? A: The TB6600 can handle a maximum pulse frequency of up to 200kHz.
