FEETECH ST-3025-C002 (12V 40KG) 85RPM High Speed Serial Bus Smart Servo Magnetic Encoder Double Shaft TTL Servo

Introduction:
- ST-3025-C002 is 12V 40kg 85RPM serial bus smart servo, aluminum alloy case is used, brushless motor, metal gearbox, Feetech self researched and developed TTL control board, 12 bit high precision magnetic coding sensor. The stall torque is 40kg.cm, can achieve 0-360 degrees any angle controllable, multi-turn continuous operation mode, it can realize the function of setting the middle point with one key, acceleration slow start and slow stop, can feedback position, speed, voltage, current, temperature, load parameters; thus, overload and over-current protection can be realized. It is suitable for application in industrial equipment, robot and Small torque drive application scenarios.

Features:
- The all aluminum alloy shell has good thermal conductivity and higher precision when machined by CNC. By anodizing the outer shell, the corrosion resistance of aluminum is further improved.
- The complete set of gears adopts a steel gear combination design, combined with a steel gear shaft and all metal upper and lower covers, which can better lock the center distance of the gears, with higher accuracy and better strength.
- Using a brushless motor as the power source, coupled with Feetech's self-developed brushless motor circuit board drive and steel tooth combination, it has a better service life and is suitable for industrial equipment application scenarios.
- At the highest accuracy, it can achieve positive and negative 7-turn absolute position control and feedback to expand the resolution value and achieve multi turn rotation. Note: The number of turns after power failure is not saved, only the absolute position feedback value is retained.
- Using a 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 accuracy is 4096 bits, and the highest position resolution is 0.088 degrees. If controlling 90 degrees, the input is 4096/360*90=1024. Control 360 degrees, the input is 4095.
- Customize acceleration and velocity values to achieve soft motion during travel. It provides better protection for gears.
- Four working modes:
Mode 1: Position mode, by default, this mode can achieve 360 degree absolute angle control and support acceleration motion.
Mode 2: Speed closed-loop motor mode, the speed will intelligently maintain without deceleration as the load increases.
Mode 3: Speed open-loop motor mode, the speed will continue to slow down as the load increases.
Mode 4: Step mode, after sending a position command, 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, based on relative position for position movement, can move continuously in one direction for multiple circles.
- Install at any position from a 360-degree angle, enter 128 at address 40 to correct the current position to the middle position with one click (2048). Very convenient to install, can improve production efficiency and reduce maintenance costs. (This function is only available for magnetic coding. The steering gear of the potentiometer can only be installed after the angle is adjusted before installation)
- Overload protection: When the external torque reaches 80% of the locked rotor, the timer is triggered to enter the protection torque (customizable).
- Overheating protection: When the temperature exceeds the set 80℃, the unloading protection is triggered.
- Real time feedback: Provide real-time feedback on parameters such as temperature, speed, voltage, load, and position.
- Support angle limit: Limit according to the angle required by the device to prevent exceeding the angle and blocking the rudder.
- Maximum torque limit: Limit the torque required by the equipment to prevent damage to the equipment caused by exceeding the torque.
- PID proportional coefficient adjustment: adjustment of motor motion, static error compensation, overshoot and other states.
- Multiple servos in series control: The servo body has 2 interfaces, which can realize the use of upper and lower servos in series.
