Feetech STS3215 Serial Bus Servo 19KG Magnetic Encoding 360 TTL Signal Level Feetech STS3215 Serial Bus Servo 19KG Magnetic Encoding 360 Degree TTL Signal Level for Robots Features: 1. Acceleration start and stop function: the speed and acceleration value can be set to make the movement effect softer. 2. High-precision magnetic encoder: using 12-bit high-precision magnetic encoder angle sensor and relative potentiometer, the angle is expanded to 360 degrees, the resolution is increased by 4 times, the absolute position is 4096, and the highest position resolution is 0.088 degrees. For example, to control 90 degrees, that is, input 4096/360*90=1024. Input 4095 when controlling 360 degrees. 3. The characteristics of serial bus: one I/O port can connect multiple servos in series up and down to reduce the occupation of serial ports, and the wiring is simple and beautiful. Multiple servos are allowed in a bus control network, so each servo is assigned a unique ID number within the network. The control command issued by the controller contains the ID information. Only the servo that matches the ID number can receive this instruction and return the answer information. 4. Parameter feedback and protection: with data feedback and protection of angle, temperature, voltage, current and load. It can collect the position of any angle (within 360 degrees) in real time, and is equipped with alarm light indication. With load and current protection. When the detection position cannot reach the target position due to stalling or the current rises to the set value, and lasts for 2S, it will enter the protection state. Resend the command to remove the protection state. The above parameters can be customized and modified. 5. Four working modes: Mode 1: Location mode by default. In this mode, 360-degree absolute angle control can be achieved to support acceleration movement. Mode 2: Speed closed-loop motor mode. As the load increases, it will maintain the speed in a intelligent. Mode 3: Speed open-loop motor mode. As the load increases, the speed continues to slow down. Mode 4: Step mode. 6. Added step mode: After sending the position command, it will move towards the target position, send the command again, and continue to step in the same direction based on the current target position, and so on. Positional motion is based on relative position and multiple revolutions can be made in one direction continuously. 7. Multi-turn and large-angle precise control: Under the highest accuracy, it can control and feedback the absolute position of plus or minus 7 revolutions, and the expansion of the resolution value can achieve hundreds of rotations. Note: After power down, the number of turns cannot be saved, only the feedback value of the absolute position is retained. 8. Calibrate its median position with one click: The 360-degree angle allows installation in any position, and 128 can be entered into 40 addresses to make the current position centered. It is very easy to install, which can improve production efficiency and reduce maintenance costs (This feature is only available in magnetic encoding. The servo of the potentiometer must be adjusted at an angle before installation). 9. Metal gear structure of bi-axial short shell: The shell adopts an engineering plastic shell of higher strength, which optimizes the center point alignment and the overall structure is more compact. The servo gear adopts a 1:345 combination of copper gears and duralumin, which has higher torque and less sound. It can be used in quadruped robots, snake-shaped robots, desktop robots, humanoid robots and robotic arms. 10. Metal servo horn: Aluminum alloy servo horn with upgraded strength and longer life.
