Dynamixel XH430-W350-R Servo

Opt for the very best in velocity, position, and PWM control

The new XH-series Dynamixel servos by Robotis (the H standing for High-performance) opens up a whole new range of possibilities for controlling your robot’s movement, trajectory or speed. These servos offer no fewer than 6 operating modes:

• Current control mode (the position is calculated based on current variations)
• Velocity control mode
• Position control mode (0-360°)
• Extended position control mode (multi-turn)
• PWM (pulse-width modulation) control mode (voltage control mode)

Robotis has also put together an exclusive advanced control table for controlling and editing a large array of data. This control table is available on Windows, Mac, or Linux.

As usual, you can use your PC (Windows, Mac, or Linux) with the USB2Dynamixel or a suitable microcontroller to control your Dynamixel servo (see below th elist of the required components):

• OpenCM9.04-A control board
• OpenCM 485 Expansion board
• SMPS charger and Power Cord for Dynamixel servomotors
• (or) LBS-10 LiPo 11V battery for Dynamixel<servomotor

Numerous mounting possibilities

The Dynamixel XH servo has a robust, yet compact design, and is more energy-efficient. Also, it increases your mounting possibilities as the connecting cables can be set up in three different positions (keeping them out of the way when the servo is on). What’s more, you can mount your servo on its articulated structure in many ways.
