    3 KW AC servo motor brake function
    I wanted to confirm the functionality of the brake on the 3KW AC servo motor. We want a brake that will engage when power is off. From the data sheet this seems to be true but I need to confirm because in our application it is critical that the brake engages in the case of sudden power loss.

    AC Servo Drive for ATO Servo Motor

    SKU: ATO-MG1000
    AC servo motor drive, 220V single phase or three phase input, 380V three phase input, is a great fit for applications requiring position, speed, and torque control methods. All the power rating range from 50w to 8.6kw of our ATO brushless AC servo motors will work perfectly with this type of servo drive.
