1-axis stepper and piezo motion controller with S-ramps and encoder feedback
The TMC457 is a high-end single axis micro stepping motion controller for 2-phase bipolar stepper motors, piezo motors (Piezo LEGS™). Via step / direction interface 3-phase stepper motors can also be controlled (requires additional TMC332). It adds to any microcontroller or processor with SPI interface. It is intended for applications, where a precise and fast, jerk-free motion profile is desired. The TMC457 supports linear and S-shaped velocity ramps. It’s chopSync™ feature allows high speed movement avoiding resonances. An encoder can be added for extremely quick and precise positioning using the internal hardware PID regulator easyPID™ and for increased reliability / fault detection. For maximum flexibility all motion control parameters (target position, target velocity, acceleration, deceleration and bow) can be changed on-the-fly at any time during motion.
