PB02 Not used in speed control operation.
Do not change the parameter.

PB03 For manufacturer setting
Do not change this value by any means. 0000h
PB04 Not used in speed control operation.
Do not change the parameter.
0
PB05 For manufacturer setting
Do not change this value by any means. 500
PB06 GD2 Load to motor inertia ratio
Used to set the motor inertia ratio to the servo motor shaft inertia moment.
When the auto tuning mode 1or the interpolation mode is selected, the result
of auto tuning is automatically used. (Refer to section 9.1.1.) In this case, the
value varies between 0 and 100.0. 7.0 Multiplier 0
to
300.0
PB07 PG1 Model loop gain
Set the response gain to the target position.
Increase the gain to improve track ability in response to the command.
When auto tuning mode 1 and 2 are set, the result of auto tuning is
automatically used. 24 rad/s 1
to
2000
PB08 Not used in speed control operation.
Do not change the parameter.
37
PB09 VG2 Speed loop gain
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 increases the response level but is more likely to
generate vibration or noise.
When auto tuning mode 1 and 2 and interpolation mode are set, the result of
auto tuning is automatically used. 823 rad/s 20
to
50000
PB10 VIC Speed integral compensation
Set the integral time constant of the speed loop.
Decreasing the setting value increases the response level but is more likely
to generate vibration or noise.
When auto tuning mode 1 and 2 and interpolation mode are set, the result of
auto tuning is automatically used. 33.7 ms 0.1
to
1000.0
PB11 VDC Speed differential compensation
Set a differential compensation.
Made valid when the proportional control (RY(n+2)7) is switched on. 980 0
to
1000
PB12 For manufacturer setting
Do not change this value by any means. 0
PB13 NH1 Machine resonance suppression filter 1
Set the notch frequency of the machine resonance suppression filter 1.
Setting parameter No.PB01 (adaptive tuning mode) to "
1"
automatically changes this parameter.
When the parameter No.PB01 setting is "
0", the setting of this
parameter is ignored.
