Description
This design presents an example distributed multi-axis servo drive over Fast Serial Interface (FSI) using C2000™ real-time controllers. Multi-axis servo drives are used in many applications such as factory automation and robots. The cost per axis, performance and ease of use are always high concerns for such systems. FSI is a cost-optimized and reliable high speed communication interface with low jitter that can daisy-chain multiple C2000 products. In this design, each F28004x part number serves as a real-time controller for a slave axis, running motor current control loop. A single F2838x part number runs position and speed control loops for all axes. The same F2838x part number also executes main axis motor control plus EtherCAT communication, leveraging its multiple cores. The design uses TI's existing EVM kits, the software is released within C2000WARE MotorControl SDK.
Features
- Demonstrates high-speed communication using fast serial interface (FSI) – with skew compensation enabled - for real-time speed, position and current command data communication between multiple products.
- Implements position and velocity control loops on the F2838x, torque/current loop on each decentralized F28004x or F28002x node.
- Up to 16 axis can be managed with one F2838x. Start and stop of each axis can be controlled simultaneously. Achieves high bandwidth and higher precision control of distributed multi-axis motor drive system.
- Uses F2838x multi-core functionality to implement speed and position control and data exchange with all distributed nodes over FSI, and executes main axis motor control and EtherCAT communication with PC.
- Demonstration of PWM sync capability across distributed axes.
- Integrated SFRA tool to support online speed and current loop tuning.
- Incremental system builds to verify the different software modules step by step.
Typical applications
- AC drive control module, HVAC motor control, Robot servo drive, Servo drive control module, Servo drive power stage module
