    A question for your 4.5kW servo motor/controller
    For your 4.5kW servo motor/controller, our performance requirements of the Idle Speed Test require very fast input changes and, likewise, very fast output speed changes. The rotational inertia and the available torque of the motor indicate that these speed changes are within the capabilities of the motor. However, I need to make sure that the motor controller is capable of responding to these fast input changes and also capable of controlling the motor to achieve these commanded output speed changes. What is the response time of the motor controller?

    ATO Responded
    The response time of the motor controller is 500Hz, and it is able to meet the performance requirements of idle Speed Test you inquire about.
