TMC457数据手册开发板套件编程器的评估演示板及套件规格书PDF

描述 Description

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
