Product Information

Back to top
The TMC457-EVAL is designed to evaluate the TMC457 high-end motion control chip in combination with a TMC246 stepper motor driver or with a Piezo LEGS® piezo motor from PiezoMotor®.

• USB 2.0 interface
• Optional RS232 interface (use 1:1 cable)
• Step / Direction input and output (3.3V level)
• 2 or 3-channel incremental encoder (5V) input
• Two stop or reference switch inputs

• Evaluation software for exploring of the TMC457 with direct register access
• Optional TMCL software allows comfortable and simple writing of stand-alone test applications
• USB driver provided
• Source code of the ARM7 processor software is provided to allow access to TMC457 via PC

• S-shaped and linear ramps with on-the-fly alteration of all parameters
• Programmable high resolution sequencer with (12 bit, 8192 entry) micro step look-up table
• Incremental encoder interface with flexible up- and down scaling to match drive resolution
• Fast and stable easyPIDTM PID controller
• 32 bit registers – from mHz to MHz / from nanometer to meter
• Reference switch processing / virtual stop switches (programmable soft limits)
• Step / direction output (with programmable timing)
• Position pulse output to trigger external events
• Synchronization of multiple axis via scalable step / direction input
• Direct interface for TMC246/TMC249 family stepper motor drivers supports StallGuard™ (pat.)
• ChopSync™ (pat. fil.) built in for best motor velocity range
• Analog high resolution motor driver control via external dual 12 bit DAC
• Automatic load angle dependent current control for energy saving
Types of Motors
• Two phase stepper motors (direct support via on-board TMC246 with up to 1.5A)
• PiezoMotors (direct sequencer support for PiezoMotors PiezoLEGS® motor)
• Any type of motor via step/direction interface (3.3V digital outputs)
