TB6600 Bipolar Stepper Motor Driver – 9–42V DC, 3.5A

The SMD-TB6600 Bipolar Stepper Motor Driver provides adjustable motor control for compatible CO2 laser engraving machines, CNC equipment, and other motion-control applications. Designed to operate two-phase bipolar stepper motors, this driver offers adjustable current settings, multiple microstepping resolutions, and pulse/direction control for accurate motor positioning.

With a 9–42V DC operating range and adjustable output current from 0.5A to 3.5A, the TB6600 can be configured for a range of compatible stepper motors. Its integrated heatsink, optically isolated control inputs, and removable terminal connections make it a practical replacement component for maintaining or repairing compatible laser machine motion systems.

Key Features

• Adjustable Motor Current: Eight selectable current settings from 0.5A to 3.5A to accommodate different motor requirements.
• Microstepping Control: Selectable full-step through 1/32-step resolutions for flexible motor positioning and motion control.
• Wide DC Input Range: Operates with compatible 9–42V DC power supplies.
• Optically Isolated Inputs: Helps reduce electrical interference between the motion controller and motor driver.
• Pulse/Direction Control: Supports standard pulse, direction, and enable control signals used by compatible motion controllers.
• Integrated Heatsink: Provides heat dissipation during normal operation when installed with suitable ventilation.
• Flexible Motor Wiring: Supports properly configured bipolar stepper motors with 4-, 6-, or 8-wire connections.

Technical Specifications

Compatibility

This driver is intended for compatible two-phase bipolar stepper motors used in CO2 laser engraving and cutting machines, CNC equipment, and other motion-control systems.

Before ordering, verify your existing driver's input voltage, motor current requirements, wiring configuration, control signal requirements, and mounting dimensions. Not all TB6600-style drivers use identical settings or connections.

The driver must be configured to match the connected motor and controller. Physical appearance or matching connector types alone do not guarantee compatibility.

Installation & Setup

• Disconnect all power before installing or removing the driver.
• Verify DC input polarity and motor coil connections before applying power.
• Set the output current and microstepping using the DIP switch chart printed on the actual driver.
• Ensure adequate ventilation around the integrated heatsink.
• Do not connect or disconnect the motor while the driver is powered.
