This document describes the 4-axis TB6560 driver board, a device designed for controlling stepper motors in CNC applications.

Function Description

The TB6560 driver board is built around the Toshiba TB6560AHQ chip, which provides high power with a maximum drive current of 3.5A. It is capable of controlling up to four axes, making it suitable for various CNC machines. The board features a bipolar constant current chopper drive with a non-resonant region, ensuring smooth motor operation without creep effect.

Key functionalities include:

• Stepper Motor Control: Drives 2 or 4 phase, 4, 6, or 8 lead stepper motors with a maximum current of 3A per axis. It supports both unipolar and bipolar stepper motors.
• Microstep Settings: Offers 1-1/16 microstep setting for enhanced accuracy and smoother operation compared to standard 1 or 1/2 step.
• Adjustable Drive Current: Allows users to set the drive current for each axis to 25%, 50%, 75%, or 100% of the full current, accommodating different stepper motor requirements.
• Spindle Control: Includes a relay spindle interface that outputs a maximum of 36V 7.5A, suitable for spindle motors or coolant pumps. Only one device can be powered by this output.
• Input Interfaces: Features a 4-channel input interface that can be used for XYZ limit switches and an emergency stop function.
• Optical Isolation: Provides full closed-type optical isolation to protect the user's computer and equipment from electrical interference.
• Safety Features: Incorporates overload, over-current, and over-temperature safety mechanisms to protect both the computer and peripheral equipment.
• Current Switching: On-board current switching allows power output to be set according to specific user requirements.
• Signal Processing: Employs a two-stage signal processing design with super anti-jamming capabilities for reliable operation.
• Software Compatibility: Supports most parallel port software such as MACH3 and KCAM4.
• Voltage Regulated Spindle Speed: The spindle speed is controlled by a parallel interface as a function of the supply voltage.

Important Technical Specifications

Usage Features

The driver board is designed for ease of use with clear configuration options.

Dip Switch Settings: The board features DIP switches for configuring current, decay mode, and microstep settings:

• Current Setting:
  • 100%: ON, ON
  • 75%: ON, OFF
  • 50%: OFF, ON
  • 25%: OFF, OFF
• Decay Mode Settings:
  • FAST: ON, ON
  • 25%: ON, OFF
  • 50%: OFF, ON
  • SLOW: OFF, OFF
• MicroStep Settings:
  • 1: ON, ON
  • 1/2: ON, OFF
  • 1/8: OFF, ON
  • 1/16: OFF, OFF

Power Supply Selection: The output current of the power supply can be calculated using the expression: Output current = Rated current of your stepper motors * quantity + 2A For example, for three 3A Nema 23 stepper motors, a 24V 11A DC power supply is theoretically recommended, but a higher power supply like 24V 15A is also acceptable. Users unsure about power supply selection are advised to contact support.

Interface Definitions: The manual provides detailed pin definitions for the Parallel Interface (1-PIN 25), Manual Interface (1-PIN15), and DB9 4-channel inputs interface, facilitating correct wiring and integration with other components.

MACH3 Software Configuration: The manual includes step-by-step instructions for configuring the MACH3 software, covering:

1. Opening MACH3: Selecting "mach3MILL" profile.
2. Accessing Ports & Pins: Navigating to the "Config" menu and selecting "Ports and Pins".

4. Motor Outputs Configuration: Defining step and direction pins for X, Y, Z, and A axes, including "Dir Low." and "Step Lo." settings.
5. Output Signals Configuration: Setting up the corresponding items in the "Output Signals" column.
6. Loading G-Code: Opening the desired G-code file.
7. Starting Operation: Clicking the "RESET" button (if flashing) and then "CYCLESTART" to begin the machining process.

Maintenance Features

The manual provides troubleshooting tips for common issues:

Simple Solutions if the Driver Does Not Work Properly:

• Software Settings: Double-check that the software settings (specifically Fig.5 and Fig.6 in the manual) are correctly configured.
• Cable Connection: Ensure the parallel cable is plugged in tightly.
• DIP Switch Changes: Always turn off the power supply before changing DIP switch settings to prevent damage.
• Power Supply Quality: Use a stable, high-quality DC power supply.
• MACH3 Issues: For problems related to MACH3 usage, refer to the Mach3 User Manual.
• Persistent Problems: If problems persist, users are encouraged to contact support.

The board's design with optical isolation and built-in safety features (overload, over-current, over-temperature) contributes to its reliability and helps protect connected equipment, reducing the need for frequent maintenance due to electrical faults.
