1 Features

The TMC457 is a high end single axis micro stepping motion controller. It adds to any microcontroller

or processor with SPI

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 “gear switching”. 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.
