Overview

The TMCM-342 is a compact 3-axis motion control module designed for stepper motor applications. It utilizes the TMC428 motion controller and an Atmel AT91SAM7X256 microcontroller to provide high-level control via TMCL or CANopen protocols. The module provides Step/Direction outputs and an SPI interface for connecting to external power drivers. Communication interfaces include RS-232, RS-485, and CAN 2.0b. It supports trapezoidal ramp profiles, various reference switch configurations, and operates on a supply voltage range of 7V to 34V DC. The document provides detailed pinouts for the 68-pin connector and application examples for connecting modules such as the TMCM-013, TMCM-023, and TMCM-035.

Use Cases

  • Multi-axis motion control systems
  • Industrial automation and robotics
  • Laboratory equipment stepper motor control
