PRODUCT DESCRIPTION
Features
- DYNAMIXEL is a robot-exclusive smart actuator with a fully integrated DC Motor + Controller + Driver + Sensor + Reduction Gear + Network in one DC servo module.
- MX-series is a new concept of DYNAMIXEL with advanced functions, such as precise control, PID control, 360-degree of position control, and high-speed communication.
- Advanced durability, degree of precision, and wider control zone were achieved thanks to the newly applied CONTACTLESS ABSOLUTE ENCODER
- 360 degrees POSITION CONTROL without dead zone
- 4,096 PRECISE RESOLUTION by 0.088 degrees
- SPEED CONTROL at ENDLESS TURN MODE
- Reliability and accuracy were advanced in the position control through PID CONTROL
- High baud rate up to 4.5Mbps
