TRINAMIC TMC457-BC
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 position, target velocity, acceleration, deceleration and bow) can be changed any time during motion.
