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.

    My Dynamixel servomotor is not detected, what can I do about it ?

    Check that your Dynamixel servomotor is correctly configured. Do not hesitate to re-flash it with the ROBOTIS Software Roboplus. After re-flash remember to re-configure it. If the issue is not solved, contact us for an advanced support.


    My motor works but it seems like there is an offset. Why ?

    The motor is probably not well mounted. Check that you correctly mounted the horns by respecting the mark.


    My Dynamixel servomotor seems blocked. I can't turn it even when it is not alimented.

    There is probably a mechanical issue with the Dynamixel servomotor. You can directly contact us to get more advance support.


    My Dynamixel servomotor is not working properly.

    Check your power supply and the system cabling (try with a different servomotor). You can also reset the servo. If nothing works, the best solution is to go through the Dynamixel servomotor checklist!


    What is the difference between Protocol 1.0 and Protocol 2.0?

    The 1.0 protocol is dedicated to the Dynamixel AX and MX series. Protocol 2.0 is for the X and Dynamixel Pro series. Protocol 2.0 control tables include PID controls which allow for more precise adjustment of the servo motor movements. Protocol 2.0 can be updated on MX series servo motors. You can refer to the protocol 1.0 and protocol 2.0 pages for more informations.
