1 Features
The TMC457 is a high end single axis micro stepping motion controller. It adds to any microcontroller
or processor with SPITM (SPI is Trademark of Motorola) interface. It is intended for applications, where
a precise and fast, jerk-free motion profile is desired. An encoder can be added for extremely quick
and precise positioning using the internal hardware PID regulator and provides for increased reliability /
fault detection. The high-resolution micro step sequencer directly controls stepper motors and piezo
motors. Wide range motion control parameters eliminate any âgear switchingâ. The TMC457 supports
linear velocity ramps and S-shaped velocity ramps. For maximum flexibility all motion control
parameters (target position, target velocity, acceleration, deceleration and bow) can be changed any
time during motion.
Highlights
⢠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 â from mHz to MHz / from nanometer to meter
⢠SPI interface to microcontroller
⢠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 limitation using encoder for stepless servo behaviour
Types of Motors
⢠Two phase stepper motors (direct sequencer support)
⢠PiezoMotors (direct sequencer support for PiezoMotorâs PiezoLEGS® motor)
⢠Any type of motor via step/direction interface
Applications
⢠Medical and laboratory equipment with high speed motion e.g. for liquid handling
⢠High end placement and positioning systems / High reliability drives
⢠Sub-micrometer positioning (piezo motors)
⢠Active stabilization with incremental encoder and fast PID regulator
