Top Performance
With the finest cutting-edge technology in the world, such as the 600-Hz response, less deviation control, and vibration suppression control, the Sigma-III series realizes high-speed but smooth positioning with minimum vibration to your machine.

 
  • The less deviation control reduces the positioning setting time for high-rigidity machines to 1ms or less.
  • The advanced control enables smooth, high-speed operations and minimizes the positioning deviation for low-rigidity machines.
  • Upgraded Follow-up Control for triangle patterns
  • 17-bit encoder mounted as a standard feature. The highly accurate absolute position data and upgraded vibration suppression control on stopping are indispensable for extra-fine processing and high-precision mounting.
  • The torque ripple is greatly reduced to assure smooth rotation.

Various Tuning Functions
Adjusts the servo according to the actual operation conditions, which reduces the setting time.

  • Advanced Autotuning
    With the remote digital operator or the built-in panel operator, set the servo drive to run so that you can tune the parameters, and the optimum settings for the load moment of inertia, the servo gains, and the filter for the connected machine will be automatically set.
    <note> To be used when the results of normal autotuning are not satisfactory.
    The advanced autotuning is applicable when the stroke is long enough to allow the auto run.
  • One-parameter
    Four servo gains can e automatically adjusted by tuning just one parameter for a servo gain with the onscreen slider.
    <note> To be used when you want to judge the results of servo tuning.
    Using this function shortens the time required for tuning.
    To be used when you want to improve the servo response after advanced autotuning.
  • EasyFFT
    A simplified version of the FFT function is pre-installed in the SERVOPACKs in the Sigma-III series.
    The mechanical vibration frequency is monitored on the remote digital operator or the built-in panel operator, and a notch filter is automatically set to minimize the vibration.
    <note> To be used this function to set a notch filter for the individual machine that is connected before adjusting the servo gains.
