  Resonance suppression by a notch

  · 4 sets of notch parameter settings, effectively suppress vibration and improve efficiency.
  · Integrated single-turn absolute value encoder, zero point memory within a limited range.
  · Provide speed and position feedforward parameter configuration to improve response speed.
 
 
  Low-frequency resonance suppression

  · If the end of the mechanical load is heavy and heavy, end vibration is prone to occur during emergency stop, which affects the positioning effect. This vibration can be effectively reduced by the low-frequency resonance suppression function.
