[Pr. PB75_Vibration suppression control 2 - Vibration frequency
after gain switching 2 (VRF21C)]
Set the vibration frequency of vibration suppression control 2 for when the gain switching is enabled.
When the setting value of this servo parameter is less than "0.1", the setting value of [Pr. PB52 Vibration suppression control
2 - Vibration frequency] is applied.
This servo parameter is enabled in the following conditions:
• [Pr. PA08.0 Gain adjustment mode selection] is set to "3" (manual mode).
• [Pr. PA24.0 Vibration suppression mode selection] is set to "1" (3 inertia mode).
• [Pr. PB02.1 Vibration suppression control 2 - Tuning mode selection] is set to "2" (manual setting).
• [Pr. PB26.0 Gain switching selection] is set to "1" (signal (CDP/C_CDP)), and [Pr. PB26.4 Gain switching 2 selection] is set
to "2" (the same condition as [Pr. PB26.0 Gain switching selection]). Or, "1" (signal (CDP2/C_CDP2)) is selected in [Pr.
PB26.4].
Switching gains during driving may cause a shock. Switch the gains after the servo motor has stopped.
[Pr. PB76_Vibration suppression control 2 - Resonance
frequency after gain switching 2 (VRF22C)]
Set the resonance frequency for vibration suppression control 2 for when the gain switching is enabled.
When the setting value of this servo parameter is less than "0.1", the setting value of [Pr. PB53 Vibration suppression control
2 - Resonance frequency] is applied.
This servo parameter is enabled in the following conditions:
• [Pr. PA08.0 Gain adjustment mode selection] is set to "3" (manual mode).
• [Pr. PA24.0 Vibration suppression mode selection] is set to "1" (3 inertia mode).
• [Pr. PB02.1 Vibration suppression control 2 - Tuning mode selection] is set to "2" (manual setting).
• [Pr. PB26.0 Gain switching selection] is set to "1" (signal (CDP/C_CDP)), and [Pr. PB26.4 Gain switching 2 selection] is set
to "2" (the same condition as [Pr. PB26.0 Gain switching selection]). Or, "1" (signal (CDP2/C_CDP2)) is selected in [Pr.
PB26.4].
Switching gains during driving may cause a shock. Switch the gains after the servo motor has stopped.
[Pr. PB77_Vibration suppression control 2 - Vibration frequency
damping after gain switching 2 (VRF23C)]
Set the damping of the vibration frequency for vibration suppression control 2 for when the gain switching is enabled.
This servo parameter is enabled in the following conditions:
• [Pr. PA08.0 Gain adjustment mode selection] is set to "3" (manual mode).
• [Pr. PA24.0 Vibration suppression mode selection] is set to "1" (3 inertia mode).
• [Pr. PB02.1 Vibration suppression control 2 - Tuning mode selection] is set to "2" (manual setting).
• [Pr. PB26.0 Gain switching selection] is set to "1" (signal (CDP/C_CDP)), and [Pr. PB26.4 Gain switching 2 selection] is set
to "2" (the same condition as [Pr. PB26.0 Gain switching selection]). Or, "1" (signal (CDP2/C_CDP2)) is selected in [Pr.
PB26.4].
Switching gains during driving may cause a shock. Switch the gains after the servo motor has stopped.
