  • High speed, high responsiveness
    Due to AC servo motor not requiring a rotor magnet, minimal rotor inertia and an excellent power rate is achieved, resulting in high responsiveness and high-precision control.
  • Maintenance-free due to the brushless feature
    There is no wear of brushes, therefore requiring no maintenance and inspection. It can also be used for a clean room.
  • Enhancement of protective functions
    The servo amplifier is equipped with various protective functions, protecting the servo amplifier. Protective functions include overcurrent protection, overload protection and motor overheating protection, etc.
