INTEGRATED CIRCUITS EtherCAT Motion Controller for 2-/3-Phase PMSM TMC8670 Datasheet
Hardware Version V1.0 | Document Revision V1.00 • 2018-June-11
The TMC8670 is a CANopen-over EtherCAT (CoE) field oriented control (FOC) servo controller for
torque, velocity, and position control. It comes with a fully integrated EtherCAT Slave Controller
(ESC), a flexible sensor engine for different position feedback and current sensing options, as well
as a complete CANopen-over-EtherCAT firmware stack for the CiA DS402 device profile. TMC8670
is a building block that enables a servo controller with only a couple of components. Features
