Ultimate system performance
The high-performance of Σ-7 SERVOPACKs translates into ultra-high-speed and ultra-high-accuracy control, which maximizes system performance.

Σ-7 SERVOPACKs can reduce speed ripples caused by motor cogging, even for machines for which speed loop gains cannot be set high. This ensures smooth operation

Enhanced vibration suppression function

• Notch filter Suppresses high-frequency vibrations of 500 Hz or higher. ⇒Number of filters increased from 2 to 5.
• Anti-resonance control adjustment Suppresses vibrations at frequencies ranging from several hundred Hz to 1 kHz. ⇒Vibrations can now be suppressed at two different frequencies (in comparison with one frequency in earlier models).
• Vibration suppression Suppresses vibrations at low frequencies (30 Hz and lower).⇒Vibrations can now be suppressed at two different frequencies (in comparison with one frequency in earlier models).

These functions can be adjusted automatically using the autotuning function.
