TMC457

TMC457 – DATA SHEET S-profile motion controller with PID feedback control and high resolution micro stepping sequencer for stepper motors and piezo motors TRINAMIC® Motion Control GmbH & Co. KG Sternstraße 67 D – 20357 Hamburg GERMANY www.trinamic.com 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 “gear switching”. The TMC457 supports linear velocity ramps and S-shaped velocity ramps. For maximum flexibility all motion control parameters (target p...
