FEATURES
It controls up to three 2phase stepper motors. All motors can operate independently. Once initialized, it performs all real time critical tasks autonomously based on target positions and velocities, which can be altered on-the-fly. So, an inexpensive microcontroller together with the TMC428 forms a complete motion control system. The microcontroller is free to do application specific interfacing and high level control functions. Both, the communication with the microcontroller and with one to three daisy chained stepper motor drivers take place via two separate 4 wire serial peripheral interfaces. The TMC428 directly connects to SPITM* smart power stepper motor drivers. Controls up to three 2-phase stepper motors Serial 4-wire interface for µC with easy-to-use protocol Configurable interface for SPITM motor drivers Different types of SPITM stepper motor driver chips may be mixed within a single daisy chain Communication on demand minimizes traffic to the SPITM stepper motor dr...
