Welcome to the Trinamic TMC2660–PA Stepper Motor Driver product training module. This presentation includes all steps necessary for getting started with a TMC2660 stepper motor design – including a minimum example of external circuitry required, Dimensioning, minimum BOM, Layout examples and discussion of a basic SPI vector for initialization. The TMC2660 is a driver for two-phase stepper motors. The TMC2660 offers an industry-leading feature set, including high-resolution micro-stepping, sensorless mechanical load measurement, load-adaptive power optimization, and low-resonance chopper operation. Standard SPI™ and STEP/DIR interfaces simplify communication.
