No. Name and function
PB09 Speed loop gain
Set this parameter when vibration occurs on machines of
low rigidity or large backlash.
Higher setting increases the response level but is liable
to generate vibration and/or noise.
When auto tuning mode 1
interpolation mode is selected, the result of auto tuning is
automatically used.
PB10 Speed integral compensation
Used to set the integral time constant of the speed loop.
Lower setting increases the response level but is liable to
generate vibration and/or noise.
When auto tuning mode 1
selected, the result of auto tuning is automatically used.
PB11 Speed differential compensation
Used to set the differential compensation.
Made valid when the proportion control (PC) is switched
on.
PB12 For manufacturer setting
Do not change this value by any means.
PB13 Machine resonance suppression filter 1
Set the notch frequency of the machine resonance
suppression filter 1.
Setting [Pr. PB01] (filter tuning mode 1) to "_ _ _ 1"
automatically changes this parameter.
When the [Pr. PB01] setting is "_ _ _ 0", the setting of
this parameter is ignored.

value
823 PB09 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 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
33.7 PB10 Speed integral compensation
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 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
980 PB11 Speed differential compensation
Set the differential compensation.
To enable the setting value, turn on PC (proportional
control).
Setting range: 0 to 1000
0 PB12 Overshoot amount compensation
Set a percentage of viscous friction torque against the
servo motor rated value the rated value.
When the response level is low or when the torque is
limited, the efficiency of the parameter may be lower.
Setting range: 0 to 100
4500 PB13 Machine resonance suppression filter 1
Set the notch frequency of the machine resonance
suppression filter 1.
When "Filter tuning mode selection" is set to "Automatic
setting (_ _ _ 1)" in [Pr. PB01], this parameter will be
adjusted automatically by adaptive tuning.
When "Filter tuning mode selection" is set to "Manual
setting (_ _ _ 2)" in [Pr. PB01], the setting value will be
enabled.
Setting range: 10 to 4500
