• Industry-leading 3.1kHz bandwidth significantly improves settling time.
  • Tuning-less capability reliably tunes servo system automatically - no user adjustment needed.
  • Powerful package of tuning functions include compensation for the effects of machine inertia, vibration, friction, and ripples in output.
  • Maintains tuning accuracy despite inertia changes up to 30:1.
  • IEC 61508 SIL3 safety certification.
  • Improved filtering minimizes inaccuracies due to electrical interference, machine resonance and mechanical vibration.
