Product Overview

The TMCM-1021 from Trinamic 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). The device provides a RS485 and GP-in interface. An integrated protocol processor supplies a high level TMCL communication. It features sensOstep magnetic encoder (max 1024 increments per rotation) e.g. for step-loss detection under all operating conditions and positioning supervision.
  • Supply voltage range from 9 to 28VDC (24VDC nominal), Motion profile calculation in real time
  • On the fly alteration of motor parameters (position, velocity, acceleration)
  • High performance microcontroller for overall system control, serial communication protocol handling
  • For position movement applications, where larger motors do not fit, higher torques are not required
  • Up to 256 microsteps per full step
  • High efficient operation and low power dissipation
  • RS485 2-wire communication interface, up to 4 multi-purpose I/P (2 shared with general purpose O/P)
  • Dynamic current control, integrated protection, stallGuard2 feature for stall detection
  • Feature coolStep for reduced power consumption and heat dissipation
  • Dimension is 28mm x 28mm x 12mm (L x W x H)
