1-axis distributed motion control module TMC457

stepper

The TMC457 is a stepper and piezo motor servo controller with S-shaped ramps for laboratory automation, 3D-printing, scanners and other automated equipment applications. The device is usable as a trapezoidal ramp generator. Furthermore the TMC457 is powered by ADI Trinamic ChopSync™ technology. The device is designed for an operating voltage of 1.5V and 3.3V. The TMC457 provides a SPI controller and SPI, S/D driver interface. Additionally it has an a/b/n incremental encoder 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 Features Highlights: S-shaped and linear ramps On-the-fly alteration of all parameters 12 bit, 8192 entry microstep look-up table Incremental encoder interface with scaling Fast and stable easyPIDTM PID controller 32 bit registers – from mHz to MHz / from nanometer to meter SPI interface to microcontroller Reference switch & virtual stop switches Step / direction output Position pulse output Scalable step / direction input Direct interface TMC246/TMC249 family stepper motor drivers w.StallGuard™ Highlights (continued): ChopSync™ built in for best motor velocity range with TMC24x driver Analog high resolution motor driver control via external dual 12 bit DAC
