The TMCM-1181 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-1181 is capable of driving up to 9A of current from each output (with proper heatsinking). It is designed for an operating voltage of 11 to 28V. The device provides a RS485, USB 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.
