Installation of Horns and Brackets

Installation of Bus Servo Horns and Brackets 1. Horn Installation Conventional 25-50KG Servos 100KG Servo 2. Bracket Installation 3. Precautions [!CAUTION] The length of the screw that fixes the body and penetrates into the body must not exceed 3mm. Otherwise, the PCB board will be pierced when locked, causing a short-circuit fault of the servo.

Recommendations for Multiple Servos in Series

Recommendations for Multiple Servos in Series 1. Reason for Group Wiring When multiple servos are connected in series, the current of a common switching power supply will be insufficient, and insufficient current will affect the normal operation of the servos. At this time, the method of grouped power supply can be adopted. 2.Connection Schematic Diagram […]

PID Tuning Method for Bus Servo

PID Tuning Method for Bus Servo 1. Basic Principle of PID Tuning Kp (Proportional Gain): Directly affects the system’s response speed and overshoot. Ki (Integral Time): Used to eliminate steady-state error, but may cause system oscillation. Kd (Derivative Time): Improves system stability and suppresses overshoot, but is sensitive to noise. [!NOTE] This document focuses on […]
