AC servo controller SD3

The SD3 Servo Amplifier is equipped with servo control which takes advantage of our expertise in LCD and semiconductor robotics. Decoupling command responsiveness and disturbance compensation using observerbased model matching and feedforward, our Servo Amplifier offers control for two degrees of freedom. Even under load fluctuations, you can expect smooth motion without needing to change tuning parameters. This control method is ideal for applications with high rigidity such as ball drives, where you will experience excellent command responsiveness. Ultimate Toughness and Low Current Consumption ―― Magnetic Absolute Encoder No other type of encoder matches the ultimate toughness of the magnetic rotary encoder - which is its greatest advantage. Magnetic rotary encoders are resistant to oil and dust, and exhibit robust power in harsh production environments. SD3 original 1 pole magnetic absolute encoder has a straightforward, hard-to-break structure, and its resolution is comparable to optical encoders. Our new encoder is your one-stop solution for the ever-challenging threesome of goals: “toughness in harsh environments”, “resolution”, and “cost”. Also, our encoder features battery-free single-turn absolute position detection. Furthermore, its current consumption upon battery backup is among the lowest in the industry. 【Robust Control】 Robust Control is a control method which maintains expected robustness and stability even when the actual specifications of robots are slightly different from the initially intended control model.
