    1. Accuracy: ATO AC servo motors realize closed-loop control of position, speed and torque, overcome the problem of stepper motor out-of-step.
    2. Speed: Good high-speed performance, rated speed can reach 1000-3000 rpm.
    3. Adaptability: ATO heavy duty servo motors with strong anti-overload capability, able to withstand a load three times the rated torque, especially suitable for occasions with instant load fluctuations and requiring quick start.
    4. Stable: Our AC brushless servo motors have smooth low-speed operation, no stepping phenomenon similar to stepper motor will occur when running at low speed, suitable for occasions occasions requiring fast response.
    5. Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds.
    6. Safety: ATO AC servo motor protection grade is IP65, which meets the waterproof and dustproof requirements.

    Tips: Features of tension servo driver

    1. The tension servo driver has the functions of closed loop tension control and open taper control, and the driver has an open and closed loop algorithm. The user only needs to set parameters but no programming. The operation is easy.
    2. It has the function of RS485 communication, which can communicate directly with touch screen or PLC.
    3. It has the mechanical static friction compensation function, makes the system more stable and control higher. The users can set the compensation value by themselves. The use of open loop taper control can have direct control of the reeling under general condition, without using the PLC DA module and pressure sensor, which reduces the euquipment manufacturing and maintenance costs substantially and also improves the reliability of the equipment.
