AC Servo Drive, K1 Series
(Communication Control: Pulse/Analog/CANopen)

K1 series servo drive comes with outstanding features in terms of intelligent control, stability and operation.

  • Intelligent Control
    Powerful internal position control mode allows for continuous multi-path planning for rich motion control; supports up to 32 data sets for planning, each set of data can be set to the number of pulses or angle required, and internal position control mode can be set for speed, acceleration, deceleration and emergency deceleration. Determining load inertial mechanical properties and setting optimal gain can be made in an automatic manner, significantly shortening system commissioning time.
  • Stable Running
    The AC servo drive features mechanical resonance frequency analysis, and is configured with two sets of trap filters with adjustable frequency (50-5000Hz) and trap depth. This effectively avoids low frequency resonance and mechanical end vibration. Vibration frequency (1-100Hz) and vibration damping can be set based on actual requirements. Frictional torque compensation reduces the effect of static friction during mechanical commutation, improving command following performance at low speeds.
  • Easy Operation
    With intuitive and simple operation, the AC servo drive supports for debugging software, mechanical characteristics analysis, parameter setting, monitoring and other functions.
