RDS3115/3120 Digital Metal Robotic Servo *1 Servo brackets *2 Metal servo arm Spindle rudder plate *1 Metal servo arm Vice axis rudder plate *1 Screws * 1 set

Features:

- Durable Metal Gear - Dual Ball Bearing - Programmable Digital Amplifier with Mosft Drive - Bottom Side Axial Mount Hole - Original factory product - Less Noise    -Orientation Angle:maximum 180 deg/270 deg - Mechanical Angle  :360 deg - Especially for the joints of the robot activities - Assembly the metal brackets size:60*82.5*27.5mm       Instructions for use: This digital servo internal servo control board using single-chip MCU control, which is relative to the traditional analog steering gear of the main differences, but the control mode is the same, are PWM pulse width adjustment angle, cycle 20ms, duty cycle 0.5 Ms ~ 2.5ms pulse width level corresponding to the steering gear 0 degrees to 180 degrees angle range, and into a linear relationship.     The biggest difference with the analog steering gear is the position lock function, to a PWM pulse width, the steering gear output angle can be locked until the next time to a different angle pulse width or power can change the angle (analog steering gear does not have the Function, the analog steering gear to lock the position need to keep the pwm signal).     In addition, the control precision is high, the linearity is good, and the control agreement is strictly the same, the output angle is accurate and the response speed is the important reason for the digital servo quality. Usually the servo controller uses 500 ~ 2500 value corresponding to the steering gear control output angle duty cycle 0.5ms ~ 2.5ms range, so that the digital servo control accuracy of the theoretical value can reach 0.09 degrees, and actually because the steering gear The gap between the group exists, the minimum control accuracy of the steering gear can reach 0.9 degrees below, relative to the host computer software slider control the minimum adjustment unit value of 10, the steering gear has a clear rotation reaction. The steering gear is strictly prohibited overload, stall will have burned machine circuit board with the risk of the motor !!!
