FEETECH SM45BL 45KG Bus Servo 360-degree Dual Shaft Metal Brushless Servo for Modbus-rtu Protocol

FEETECH SM45BL 45KG Bus Servo 360-degree Dual Shaft Metal Brushless Servo for Modbus-rtu Protocol

Features:
- 45KG all-metal brushless servo adopts an all-in-one structure: Reduction gear + drive motor + sensor + control board + bus communication. New concept power execution module is developed based on high reliability, scalability and basic functions.
- Acceleration start and stop: Compared with ordinary servos, SM45BL can achieve acceleration start and stop. This is similar to automatic car starting and stopping. 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 it can be compensated to a specified position by position correction. 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: SM45BL 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.
- It supports for SMS FEETECH RS485 or Modbus protocol. SMS FEETECH RS485 version is for FD software to debug. While the version for Modbus protocol is for mbpoll software to debug. Both of the versions can be angle-limited, support baud rate modification, overload reduction torque output, over-current, over-temperature, over-voltage and under-voltage protection. It will automatically stop the output torque when there is something wrong with the angle sensor. And its LED will sound an alarm.
- 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.
- PWM control mode: It can output constant force to achieve forward and reverse direction control.

Attention:
(1) When working continuously within 3A current, the SM45BL serial servo will reach the maximum safe working temperature.
(2) Under the quiescent working current, the SM45BL serial servo is energized, but it does not move.
(3) Under the condition of no-load current operation, the SM45BL serial servo moves under the condition of no load.
(4) Under the condition of stalled current, this is the current of the servo at the maximum torque output.
(5) The baud rate can be modified to 500K, 250K, 128000, 115200, 76800, 57600 and 38400.
(6) 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.
(7) 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.
