TB6600 Stepper Motor Driver

Safety Statement

The author of this document is not liable or responsible for any accidents, injuries, equipment damage, property damage, loss of money or loss of time resulting from improper use of electrical or mechanical or software products.

Assembling electrical and mechanical CNC machine components like power supplies, motors, drivers or other electrical and mechanical components involves dealing with high voltage AC (alternating current) or DC (direct current) and other hazardous items which can be extremely dangerous and needs high attention to detail, experience, knowledge of software, electricity, electro-mechanics and mechanics.

BEFORE MAKING ANY CONNECTIONS OR DISCONNECTIONS POWER MUST BE REMOVED FROM THE DEVICE AND THE CONTROLLER. FAILURE TO DO SO WILL VOID ANY AND ALL WARRANTIES.

Before starting please read through all the instructions.

Note: : Any Mains power connections must be installed by a Licensed electrician or suitability qualified person.

Errors and omissions excepted

1.0 Introduction

The TB6600 Stepper Motor Driver is a two-phase stepper motor driver. It supports speed and direction control. You can set its micro step and output current with 6 DIP switches. There are 7 kinds of micro steps (1, 2 / A, 2 / B, 4, 8, 16) and 8 kinds of current control (0.5A, 1A, 1.5A, 2A, 2.5A, 2.8A, 3.0A, 3.5A). All signal terminals adopt high-speed optocoupler isolation, enhancing its anti-high-frequency interference ability.

1.1 Features

  • Supports 8 levels of current control
  • Supports 7 levels of micro step adjustment
  • Interfaces adopt high-speed optocoupler isolation
  • Automatic semi-flow to reduce heat
  • Large area heat sink
  • Anti-high-frequency interference ability
  • Input anti-reverse protection
  • Overheat, over current and short circuit protection

1.3 Application

Suitable for a variety of small and medium sized automation equipment and instruments, such as engraving machines, marking machines, cutting machines, laser typesetting, plotters, CNC machine tools, and handling devices.

2.1 Signal Input

The TB6600 driver accepts step and direction inputs, typically in the form of digital pulses, where each pulse on the step input causes the motor to move one step in the direction specified by the direction input.

2.2 Motor Machine Winding

The TB6600 is designed to drive bipolar stepper motors, which typically have two windings or phases.  It’s critical to correctly identify and connect the motor windings to the TB6600’s output terminals. Incorrect wiring can result in erratic motor behaviour or failure to rotate.

2.4 Wiring Instructions

There are three input signals

 

Step pulse signalPUL +, PUL-;
Direction signalDIR +, DIR-;
Enable signalEN +, EN-.

The driver supports common-cathode and common-anode circuit, you can select one according to your requirements.

2.4.1 Common-Anode Connection

Connect PUL +, DIR + and EN + to the power supply of the control system. If the power supply is + 5V, it can be directly connected. If the power supply exceeds +5V, a current limiting resistor R must be added externally to ensure that the controller pin can output 8 – 15mA current to drive the internal optocoupler.

2.4.2 Common-Cathode Connection

Connect PUL -, DIR – and EN – to the ground terminal of the control system. Pulse signal connects to PUL+; direction signal connects to Dir+ ; Enable signal connects to EN+. As shown below:

Note: When “EN” is in the valid state, the motor is in a free state (Off-line mode). In this mode, you can adjust the motor shaft position manually. When “EN” is in the invalid state, the motor will be in an automatic control mode.

2.5 Microcontroller Connection 

Below is a common-anode connection (“EN” not connected).

3.0 DIP Switch Settings

3.1 Micro-Step Settings

The follow table shows the TB6600 Driver Micro step settings. The first 3 DIP switches are used to set the micro steps.

Step Angle = Motor Step Angle / Micro Step

E.g. A stepper motor with a 1.8° step angle, the final step angle under “Micro step 4” will be 1.8°/4=0.45°

4.0 Enable/Off-Line Function

If you turn on the Enable / Off-line function, the motor will enter a free state, you will be able to turn the motor shaft freely and any pulse signal will be ignored. If you turn it off, the driver will be in automatic control mode.

Note: Generally, EN terminal is not connected.
