TRINAMIC TMC429-LI
The TMC429 is fully downwards compatible to the TMC428.
The TMC429 is a miniaturized low cost, high performance stepper motor controller for up to three motors. It integrates all real time critical tasks in reliable, dedicated hardware: An integrated motion ramp profile generator as well as an adaptable microstep sequencer with microstep RAM table. Advanced stop- and reference switch handling allows for precise and fast referencing as well as on-the-fly position checking. Automatic motor current control gives high motor dynamics while saving energy. The interrupt output can generate precise position pulses.
The TMC429 connects to the recent coolStep™ drivers (TMC260, TMC262 and TMC389) via Step- & Direction signals (S/D) or to the classic TRINAMIC drivers TMC236, TMC239, TMC246 and TMC249 via SPI®. The communication with the host microcontroller is done with an extra SPI® interface. The host just needs to do high-level control tasks, e.g. giving the command: Drive motor 2 to position 1000. The TMC429 automatically calculates the motion ramp based on velocity and acceleration parameters.
