From Trinamic: "Trinamic launches dedicated EtherCAT motion controller IC"

Aug 29, 2018
 

Hamburg, 13 Aug. 2018 - TRINAMIC Motion Control GmbH & Co. KG combines the best of both worlds in the TMC8670. It integrates all algorithms for a high-end, fast field-oriented control and high-performance real-time fieldbus interface. Suitable for 3-phase BLDC and BLAC motors as well as 2-phase stepper motors, the TMC8670 embodies decades of experience with motor control.

“We see EtherCAT gaining relevance in the embedded automation domain, where tight space constraints drive miniaturization,” explains Michael Randt, Founder and CEO of Trinamic. “This component is designed with precise and dynamic robot drives in mind, where controllers and servo drives are distributed in the joints. Since we’ve built the drive electronics for KUKAs youBot several years ago, more and more small, decentralized robot designs appear on the market demanding space saving and high-performance solutions.”

A single axis embedded servo controller for robotics, manufacturing, and automation, the TMC8670 is designed for an operating voltage of 1.2V… 3.3V. Having an SPI-ADC interface, position interpolators, and different position sensor interfaces, the TMC8670 is a high-performance building block that enables a real-time servo controller with only a couple components. it is prepared for typical encoders used in robotics and industrial automation as well as embedded motion control systems.

With a PWM engine including space vector pulse width modulation (SVPWM), the IC is suitable for demanding, low inductance motors and highest dynamic positioning tasks. With all the control loops implemented in dedicated hardware, the TMC8670 executes the real-time critical tasks faster than any software-based solution and reduces the development time to a minimum.

The TMC8670-BI comes in a FCSG325 (11x11) package. The component and the evaluation board TMC8670-EVAL are available for shipment from September 2018. The device meets the -40°C to 125°C automotive grade temperature specification.

Features and benefits:

  • Field-oriented control (FOC) servo controller
  • Torque control (FOC), velocity control, position control
  • Sensor engine (Hall analog/digital, encoder analog/digital)
  • Support for 3-phase PMSM and 2-phase stepper motors
  • PWM engine including SVPWM
  • EtherCAT® interface with CoE protocol CiA 402 drive profile
  • UART interface
