    i-SERVO


    i-SERVO adopts a closed-loop stepping servo motor system, the biggest feature can be diversified torque control and high-precision positioning, mode switching will not have the vibration problem of general servo motors.
    Features
    1. Four drive modes are available: "position control", "speed control", "down pressure control" and "torque control"
    2. High speed, high torque
    3. High-precision position positioning: equipped with optical encoders with resolutions up to 6400/9600/12800 / 16000ppr
    4. High reliability system: equipped with optical encoder, stepping servo system without losing step.
    5. High response: The instant torque output can reach 150% of the rated torque, and the response is fast, which is quite suitable for sensitive operation.
    6. Low heat generation and energy saving: Since the optimal current will be adjusted according to the load when the control is executed, high-efficiency operation can be achieved.
    7. Shorten the setting time when stopping
    8. High-speed position interception and output comparison
    9. Position motion control mode
