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