Servo Protocols & Control Methods

Choose the servo communication protocol or control method that fits your project. UART servo products and RS-485 servo products use the same packet and command protocol but different physical interfaces. CAN Bus servo products use a separate CAN communication protocol, while PWM digital servo products are controlled by pulse signals. These options cover the main servo interfaces used across current servo product families.

Communication Protocols

• UART/RS-485 Servo Communication Protocol

  Review the packet format, control commands, responses, and parameter definitions shared by UART and RS-485 bus servo products.

• CAN Bus Servo Communication Protocol

  Review the standard frame format, commands, node communication, control parameters, and feedback rules for CAN Bus servo products.

Control Methods

• PWM Control Method

  Review PWM pulse control, wiring examples, stall protection, and troubleshooting for digital servo applications.

Interface Comparison

• Servo Interface & Control Method Comparison

  Compare the wiring, communication, and application characteristics of UART, RS-485, CAN Bus, and PWM.
