TMCM-1076 Hardware Manual

Hardware Version V1.10 | Document Revision V1.00 • 2018-JUN-25

The TMCM-1076 is an easy to use stepper motor driver module. The module is controlled via a

step and direction interface. One configuration pin selects the current control mode between

stealthChop™ for absolute silent motor control and spreadCycle™ for high speed. A TTL UART

interface allows for more advanced configuration and permanent parameter storage via TMCL™-

IDE.

Features

• Supply V10. . . +30V DC
• Up to 3A RMS motor current
• Step and direction interface
• microPlyer™ to 256 µ-steps
• stealthChop™ silent PWM mode
• spreadCycle™ smart mixed decay
• stallGuard2™ load detection
• coolStep™ autom. current scaling
• UART configuration interface

Applications

• Lab-Automation
• Manufacturing

• Robotics
• Factory Automation

• CNC
• Laboratory Automation
