INFO
The TMC454 is a high-end motion controller for all common 2-,
3-, and 5-phase stepper motors. It provides encoder feedback for
high reliability or high position resolution drives. A large set of
motion control features is included on this IC. The various func-
tion blocks are hardwired and „ready-to-use“. All processes can
be serialized using the instruction based interface. A complete
linear & S-shaped ramp generation unit is integrated within the
TMC454. All dynamic parameters can be adjusted for a given
application in a very broad range. The CPU is relieved from all
time critical tasks like ramp calculation or microstep generation.
Thus CPU and software engineer can focus on higher level mo-
tion control jobs. In many applications, the TMC454 reduces the
time time-to-market, and it saves costs for software develop-
ment and hardware engineering. The TMC454 turns stepper
motors into easy to use peripherals!
The TMC454 is upwards function compatible to its predecessor
TMC453.
