Speed loop
gain This is used to set the gain of the speed loop.
Set this parameter when vibration occurs on machines of low rigidity or large
backlash. Increasing the setting value will also increase the response level but will
be liable to generate vibration and/or noise.
The setting of the parameter will be the automatic setting or manual setting
depending on the [Pr. PA08] setting. Refer to the table of [Pr. PB08] for details.
Setting range: 20 to 65535 823
[rad/s]
PB10
VIC
Speed
integral
compensation This is used to set the integral time constant of the speed loop.
Decreasing the setting value will increase the response level but will be liable to
generate vibration and/or noise.
The setting of the parameter will be the automatic setting or manual setting
depending on the [Pr. PA08] setting. Refer to the table of [Pr. PB08] for details.
Setting range: 0.1 to 1000.0 33.7
[ms]
PB11
VDC
Speed
differential
compensation This is used to set the differential compensation.
To enable the setting value, turn on PC (proportional control).
Setting range: 0 to 1000 980
PB12
OVA
Overshoot
amount
compensation Set a viscous friction torque per percent to the servo motor rated speed.
When the response level is low, or when the torque is limited, the efficiency of the
parameter can be lower.
Setting range: 0 to 100 0

Set the notch frequency of the machine resonance suppression filter 1.
When "Automatic setting (_ _ _ 1)" of "Filter tuning mode selection" is selected in
[Pr. PB01], this parameter will be adjusted automatically.
When you select "Manual setting (_ _ _ 2)" of "Filter tuning mode selection" in [Pr.
PB01], the setting value will be enabled.
Setting range: 10 to 4500 4500
[Hz]
Set the shape of the machine resonance suppression filter 1.
When you select "Automatic setting (_ _ _ 1)" of "Filter tuning mode selection" in [Pr. PB01], this parameter will be
adjusted automatically.
Set manually for the manual setting. PB14
