Part details & applications

The TMCM-1140 is a single axis stepper motor controller/driver module for sensorless load dependent current control. The device is powered by ADI Trinamic StallGuard2^™, CoolStep^™ and SpreadCycle^™ chopper technology and has a trapezoidal ramp generator. The TMCM-1140 is capable of driving up to 2.8A of current from each output (with proper heatsinking). It is designed for an operating voltage of 9 to 28V. The device provides a RS485, CAN, USB, S/D and encoder interface. An integrated protocol processor supplies a high level TMCL/ CANopen 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.
