INFO
The TMC429 is a miniaturized low cost, high performance step-
per 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 micro-
step 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 is fully downwards compatible to the TMC428 and
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.
