PB29 
GD2B 
Load to motor 
inertia ratio/ 
load to motor 
mass ratio 
after gain 
switching 
This is used to set the load to motor inertia ratio for when gain switching is enabled. 
This parameter is enabled only when "Gain adjustment mode selection" is "Manual 
mode (_ _ _ 3)" in [Pr. PA08]. 
 
 
 
Setting range: 0.00 to 300.00 
PB30 
PG2B 
Position loop 
gain after 
gain 
switching 
Set the position loop gain when the gain switching is enabled. 
When you set a value less than 1.0 rad/s, the value will be the same as [Pr. PB08]. 
This parameter is enabled only when "Gain adjustment mode selection" is "Manual 
mode (_ _ _ 3)" in [Pr. PA08]. 
 
Setting range: 0.0 to 2000.0 
PB31 
VG2B 
Speed loop 
gain after 
gain 
switching 
Set the speed loop gain when the gain switching is enabled. 
When you set a value less than 20 rad/s, the value will be the same as [Pr. PB09]. 
This parameter is enabled only when "Gain adjustment mode selection" is "Manual 
mode (_ _ _ 3)" in [Pr. PA08]. 
 
Setting range: 0 to 65535 
PB32 
VICB 
Speed 
integral 
compensatio
n after gain 
switching 
Set the speed integral compensation when the gain changing is enabled. 
When you set a value less than 0.1 ms, the value will be the same as [Pr. PB10]. 
This parameter is enabled only when "Gain adjustment mode selection" is "Manual 
mode (_ _ _ 3)" in [Pr. PA08]. 
 
 
Setting range: 0.0 to 5000.0 
PB33 
VRF1B 
Vibration 
suppression 
control 1 - 
Vibration 
frequency 
after gain 
switching 
Set the vibration frequency of the vibration suppression control 1 for when the gain 
switching is enabled. 
When you set a value less than 0.1 Hz, the value will be the same as [Pr. PB19]. 
This parameter is enabled only when the following conditions are fulfilled. 
"Gain adjustment mode selection" in [Pr. PA08] is "Manual mode (_ _ _ 3)". 
"Vibration suppression control 1 tuning mode selection" in [Pr. PB02] is "Manual 
setting (_ _ _ 2)". 
"Gain switching selection" in [Pr. PB26] is "Input device (gain switching (CDP)) (_ 
_ _ 1)". 
Switching during driving may cause a shock. Be sure to switch them after the servo 
motor stops. 
 
Setting range: 0.0 to 300.0 
PB34 
VRF2B 
Vibration 
suppression 
control 1 - 
Resonance 
frequency 
after gain 
switching 
Set the resonance frequency for vibration suppression control 1 when the gain 
switching is enabled. 
When you set a value less than 0.1 Hz, the value will be the same as [Pr. PB20]. 
This parameter will be enabled only when the following conditions are fulfilled. 
"Gain adjustment mode selection" in [Pr. PA08] is "Manual mode (_ _ _ 3)". 
"Vibration suppression control 1 tuning mode selection" in [Pr. PB02] is "Manual 
setting (_ _ _ 2)". 
"Gain switching selection" in [Pr. PB26] is "Input device (gain switching (CDP)) (_ 
_ _ 1)". 
Switching during driving may cause a shock. Be sure to switch them after the servo 
motor stops.
