FEETECH SM85CL 12V 85KG Bus Servo Brushless Servo w/ URT-1 Signal Board for Modbus-rtu Protocol

FEETECH SM85CL 12V 85KG Bus Servo Brushless Servo w/ URT-1 Signal Board for Modbus-rtu Protocol

Features:
- The brushless servo adopts reduction gear + brushless motor + 12bit high-precision 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: SM85CL can achieve acceleration start and stop. This is similar to automatic car starting and stopping. This is similar to automatic infinitely variable transmission. It 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. And set the current point as the middle point by one key. Reduce the installation process, reduce the error rate, improve the efficiency of mass production and reduce the cost of manual maintenance.
- Multi-turn large angle: The servo can achieve plus or minus 7 turns at the highest angular resolution, adjust the angle resolution, and can achieve plus or minus 100+ turns. 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. Closed-loop design, dynamic monitoring, servo protection, and longer service 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° and 0.088° resolution).
- 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.
- One key to set the middle point: Set the current position as the initial position or middle point.
