Dynamixel XH540-V270-R Servo Motor

Dynamixel XH540-V270-R servo motor: 6 closed loop control modes

This Dynamixel servo offers numerous advantages in terms of durability, connection quality and, most importantly, control. Velocity, position and torque closed loop controls, including in PWM mode, will delight fans of radio-controlled vehicles.

This Robotis servo includes a coreless Maxon motor, which is more reliable than the equipment installed on the XM serie. And its precious metal and engineering plastic casing delivers satisfactory heat dissipation, with style.

The XH series servos come with a JST connector, ensuring more reliable communications than a Molex connector. Nevertheless, to connect your servo to a compatible OpenCM controller or U2D2Dynamixel stick, you can use a JST cable.

Precautions for mounting your Robotis XH540-V270-R servo

With the XH series, you can connect multiple servos in a chain for a much cleaner and easier assembly. Position your JST cable carefully to ensure that the wires do not get tangled up, which would damage the cable. Three wiring options are available, so you can choose the best one for your project.

If you want to attach your Dynamixel servo to a frame, make sure to use a standoff so that the fixing screw does not damage the frame.
