A 12V servo with a TTL interface

The XM540-W270-R actuator is the newest addition to the increasingly wider range of Dynamixel X servos. It has a reduction ratio of 272.5:1 and can generate a starting torque of 106 kg.com (10.6 N.m). It handles supply voltages between 11.1 and 14.8V and is equipped with an RS-485 multi-drop bus interface. (Please note that if you’re looking for a TTL-interfaced Dynamixel servo, you’ll want a model with a serial number ending with a T.)

Servomoteur Dynamixel XM540-W270-R

A worthy representative of the Dynamixel X series

Like with all the actuators in the Dynamixel X series previously released by Robotis, the XM540-W270-R servo includes a variety of valuable features for robotics enthusiasts and researchers or teachers:

  • Extensive feedback: position, speed, temperature, input voltage, and so on;
  • Many control options: torque, PWM, current-based torque, velocity, and so on;
  • Real energy savings compared with the previous versions;
  • An absolute contactless encoder offering a 360° control mode;
  • A more compact case in aluminium offering improved heat sink;
  • Various wiring options and a flap at the back of the case to minimise cable stress.
