FEETECH SM8512BL 85KG 360-degree Bus Servo RS485 All Metal Dual Shaft Brushless Servo w/ Steel Gears

FEETECH SM8512BL 85KG 360-degree Bus Servo RS485 All Metal Dual Shaft Brushless Servo w/ Steel Gears

Features:
- 12V/24V brushless intelligent micro servo motor of high torque: reduction gear + brushless motor + high-precision 12-bit magnetic encoder sensor + FEETECH control board + RS485 communication. New concept power execution module is developed based on high reliability, scalability and basic functions.
- Customizable variable speed control. It enables acceleration start and stop, similar to an automatic continuously variable transmission. This can reduce the instantaneous bite force of the gear, reduce the impact force caused by the output shaft due to the moment of stopping, and improve the service life of the servo.
- Can be installed at any angle. When installing the servo to your device, you do not need to find the middle position, you can install it at any angle. One click to set the current midpoint position. Reduce the installation process, reduce the error rate, improve the efficiency of mass production and reduce the cost of manual maintenance. The parameters can be adjusted by the software for FD.
- Multi-turn large angle: SM8512BL can achieve plus or minus 7 turns at the highest angular resolution, adjust the angle resolution, and can achieve plus or minus 10+ turns (Note: the number of turns cannot be saved when there is power failure). It can realize more scenario applications and modular design shortens the development cycle.
- Parameter feedback and multi-layered protection: The bus servo has the following parameter feedback mechanisms: temperature, load, speed, current, voltage, position, over-temperature, overload, over-voltage and over-current protection. With the software, you can monitor parameter changes in real time. While the device is running, you can dynamically monitor changes in the data. When the internal and external environment changes (such as torque overrun, stall, temperature overrun, etc.), it will make the protection mechanism worked, thereby protecting the servo itself. The closed-loop design facilitates dynamic monitoring, protects the servo itself, and prolongs life.
- Open PID motor parameter debugging: It adopts high-precision brushless motor and open PID to debug motor motion effects, such as motor motion hardness, static error compensation, overshoot and others. It can achieve a motor motion effect that is more in line with the set.
- Magnetic encoder sensors: 12-bit high-precision sensor is used to measure position.
- High resolution: non-contact absolute 12-bit encoder (360° 0.088°).
- Serial bus type: support serial bus daisy connection and 254 ID addresses to choose.
- Position servo control mode: can rotate 0~360° and multi-turn at any absolute angle.
- Speed control mode: constant speed control of continuous rotation in the forward and reverse directions, with wide speed regulation range.
- Set the middle position with one key. You can freely define the current position as the initial position or the midpoint.

Attention:
- Under the quiescent working current, the SM8512BL brushless serial servo is energized, but there is no movement.
- Under the condition of no-load current operation, SM8512BL brushless serial servo moves under the condition of no load.
- In the case of blocked current, this is the current of SM8512BL brushless serial servo when it outputs the maximum torque.
- Baud rate can be modified to 500K, 250K, 128000, 115200, 76800, 57600 and 38400.
- The actual maximum number of bus nodes available depends on the power supply capacity and the allowable current specification of the cable. It is recommended that 8 groups of servos be equipped with one group of power supply.
- The stall torque is the maximum stall torque of the servo, and 1/3-1/5 of this value is selected as the suitable working point for the actual working torque.
