Overview

The DYNAMIXEL AX-12A servo is a highly efficient, all-in-one solution that combines a DC motor, controller, driver, and network in a single package of 55g and 32 x 50 x 40 mm in dimension.It is rated for 9.0V to 12.0V DC provding 1.5 N.m (Newton-metre) of stall torque at 12V and 1.5A of stall current, also it has an RPM of 59 rev/min at 12V.

The AX-12A utilizes a TTL serial communication protocol, allowing for daisy-chaining multiple servos together to create complex servo systems with fewer wires. It operates at a range of baud rates, from 7,843bps to 1Mbps, giving speed and flexibility in communication.

It has a resolution of 0.29° deg/pulse and step of 1 pulse/rev offering precise control over movements, also the servo can be controlled in terms of position, speed and torque. It provides real-time feedback on various parameters including position, speed, temperature, voltage, and load. This capability is essential for advanced control schemes where monitoring and adjusting based on dynamic conditions are required.

Designed for versatility and ease of use, It stands out in the market due to its robust construction, precision control capabilities, and advanced features that cater to a wide range of robotics and automation needs.

Features

Compliance Margins and Slopes: These settings adjust the servo's response stiffness to control commands, allowing for more fluid and natural movements.

Overload Protection: Built-in protection mechanisms guard against overload, overheating, and overvoltage conditions, ensuring long-term reliability and performance.

Upgradability: The servo firmware can be updated to incorporate new features or rectify existing issues, thereby extending the lifespan and utility of the device.
