• Use this parameter to set the Servomotor’s allowable operating range for the position command
input range.
• An overrun limit error (alarm code 34) will occur if the setting is exceeded.
• The function will be disabled if the setting is 0.
• For details, refer to
Explanation of Settings
• The instantaneous speed observer can both increase the responsiveness and reduce vibration at
stopping by improving the speed detection accuracy for devices with high rigidity.
• The Inertia Ratio (Pn20) must be set correctly.
• The Instantaneous Speed Observer Setting (Pn27) will be 0 (disabled) if the Realtime Autotuning
Mode Selection (Pn21) is not set to 0 (enabled).
• Use this parameter to set the notch frequency of notch filter 2 for resonance suppression.
• The notch filter will be disabled if the setting is 1500.
• Use this parameter to set the notch width of notch filter 2 for resonance suppression.
• Increasing the setting will increase the notch width. Normally, use the default setting.
• Use this parameter to set the notch depth of notch filter 2 for resonance suppression.
• Increasing the setting will decrease the notch depth and the phase lag.
• Use this parameter to set vibration frequency 1 for damping control to suppress vibration at the
end of the load.
• Measure the frequency at the end of the load and make the setting in units of 0.1 Hz.
• Setting frequency: 10.0 to 200.0 Hz. The function will be disabled if the setting is 0 to 9.9 Hz.
• Refer to
on page 7-35 for more information.
