[Pr. PB77_Vibration suppression control 2 - Vibration frequency
damping after gain switching 2 (VRF23C)]
Initial value
0.00
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)), 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)) is selected in [Pr. PB26.4].
Switching gains during driving may cause a shock. Switch the gains after the servo motor has stopped.
[Pr. PB78_Vibration suppression control 2 - Resonance
frequency damping after gain switching 2 (VRF24C)]
Initial value
0.00
Set the damping of the resonance 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)), 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)) is selected in [Pr. PB26.4].
Switching gains during driving may cause a shock. Switch the gains after the servo motor has stopped.

[Pr. PB79_Gain switching 2 - Model control gain (PG1C)]

Initial value
0.0 [rad/s]
Set the model control gain for when the gain switching is enabled.
When the setting value of this servo parameter is less than "1.0", the setting value of [Pr. PB07 Model control gain] is applied.
This servo parameter is enabled in the following conditions:
• [Pr. PB26.0 Gain switching selection] is set to "1" (signal (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)) is selected in [Pr. PB26.4].
