Overview

Highlights
  • Motion profile calculation in real-time
  • On the fly alteration of motor parameters (e.g. position, velocity, acceleration)
  • High performance microcontroller for overall system control and serial communication protocol handling
  • For position movement applications, where larger motors do not fit and higher torques are not required
Bipolar Stepper Motor Driver
  • Up to 256 microsteps per full step
  • High-efficient operation, low power dissipation
  • Dynamic current control
  • Integrated protection
  • stallGuard2™ feature for stall detection
  • coolStep™ feature for reduced power consumption and heat dissipation
Encoder
  • sensOstep™ magnetic encoder (max. 1024 increments per rotation) e.g. for step-loss detection under all operating conditions and positioning supervision
Interfaces
  • Up to 4 multi-purpose inputs (2 shared with general purpose outputs)
  • 2 general purpose outputs
  • RS485 2-wire communication interface
Software
  • TMCL™: standalone operation or remote controlled operation, program memory (non volatile) for up to 876 TMCL commands, and PC-based application development software TMCL-IDE available for free.
Electrical and mechanical data
  • Supply voltage: +24V DC nominal (9 to 28V DC max.)
  • Motor current: up to 0.7A RMS (low current range, programmable) or 1.4A RMS (high current range, programmable, new additional range since hardware version 1.4)

The TMCM-1021 is a single axis stepper motor controller/driver module for sensorless load dependent current control. The device is powered by Trinamic StallGuard2™, CoolStep™ and SpreadCycle™ chopper technology and has a trapezoidal ramp generator. The TMCM-1021 has been designed for coil currents up to 0.7A RMS (low current range, programmable) or 1.4A RMS (high current range, programmable with new additional range since hardware version 1.4). It is designed for an operating voltage of 9 to 28V. The device provides a RS485 and GP-in interface. An integrated protocol processor supplies a high level TMCL communication.

All you need to get started is a power supply and ADI Trinamic's free and easy to use TMCL-IDE. This graphical user interface allows quick setup and supports the use of commands in direct mode, monitors real-time behavior visualized in graphs, and logs and stores data.

TMCL-IDE

Short for Trinamic Motion Control Language-Integrated Development Environment, the TMCL-IDE is an integrated development environment made for developing applications using ADI Trinamic™ modules and chips. The GUI provides tools for easily setting parameters, for visualizing data in real-time, and for developing and debugging stand-alone applications with TMCL.
