TMC 453
High End Motion Controller with Encoder Interface for Stepper Motors
The
TMC453
is a high-end motor 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 function 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 TMC453. 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 micro-
step generation. Thus CPU and software engineer can focus on higher level motion con-
trol jobs. In many applications, the TMC453 reduces the time time-to-market, and it saves
costs for software development and hardware engineering. The TMC453 turns stepper
motors into easy to use peripherals!
A PC based evaluation kit is available that comes together with software for demonstration
of all TMC453 capabilities.
