The various func- • full step, half step, sine-step tion blocks are hardwired and „ready-to-use“. All processes can • relieves CPU from all time critical tasks be serialized using the instruction based interface. A complete • incremental encoder interface linear & S-shaped ramp generation unit is integrated within the • pulse generation from mHz to MHz TMC454. All dynamic parameters can be adjusted for a given • S-shaped and linear ramp generation application in a very broad range. The CPU is relieved from all • PID controller for holding the position time critical tasks like ramp calculation or microstep generation. • synchronization of multiple TMC454 Thus CPU and software engineer can focus on higher level mo- • direct SPI interface for TMC246/TMC249 stepper driver IC family The TMC454 is a high-end motion controller for all common 2-, tion control jobs.
