    • Accuracy: ATO AC servo motors realize closed-loop control of position, speed and torque, overcome the problem of stepper motor out-of-step.
    • Speed: Good high-speed performance, rated speed can reach 1000-3000 rpm.
    • 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.
    • 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.
    • Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds.
    • Safety: ATO AC servo motor protection grade is IP65, which meets the waterproof and dustproof requirements.

    Tips: Servo motor does not run when the pulse is output, how to solve?

    1. Monitor the current pulse output value of controller and check if pulse output indicator lamp flashes to confirm that the controller has performed command pulse and has output pulse normally.
    2. Check if the control cable, power cable, encoder cable between controller and driver are matched incorrectly damaged or contacted poorly.
    3. Check if the brake of servo motor equipped with brake has been turned on.
    4. Monitor the panel of servo driver to confirm if the pulse command has been input.
    5. Run command is normal.
    6. For control mode, always choose position control mode.
    7. Check if the type of input pulse set by servo driver matches with that of command pulse.
    8. Ensure that positive side drive prohibition, negative side drive prohibition signals and deviation counter reset signal are not input and the servo motor runs normally if load is removed, then check the mechanical system.
