CF35-12 User Guide

Overview

Introduction

CF35-12 is a programmable dual-axis constant force serial bus servo with a stall torque of 35KG.CM. It has an all-aluminum alloy shell and an external high-strength aluminum alloy steering wheel. It uses a 360° high-precision magnetic encoder and can perform angle control within a 360° range. It can set any angle as the servo center position through program control; It can also be switched to continuous motor mode, multi-turn continuous rotation and other working modes, with built-in acceleration start-stop function, making the action smoother. Each bus servo has two interfaces, allowing the servos to be connected in series. Theoretically, up to 253 servos can be controlled simultaneously, and each servo can obtain its current angle, load, voltage, mode, and other information. It can be used to build multi-axis small-volume steering robot projects such as quadruped, hexapod, and robotic arm, and easily handle large objects.


Features

  • 360° magnetic encoder, high precision, angle control accuracy up to 360°/4096
  • Any angle can be set to the servo center position for easy assembly
  • Acceleration start-stop function, smoother motion effects
  • Compact structure design, more beautiful product appearance
  • Wide voltage input of 9-12.6V, can be directly powered by 2S or 3S lithium batteries
  • Stall torque up to 35kg.cm@12V
  • Multiple working modes can be set:
    • Angle control mode
    • Motor constant speed control mode
    • Motor constant current control mode
  • Can be used in series to control up to 253 bus servos at the same time (provided that the power supply is sufficient) and obtain feedback information for each bus servo
