PB05 This parameter is not used. Do not change the value. 500
PB06 GD2 Load to motor inertia moment ratio
Used to set the ratio of the load inertia moment to the servo motor shaft inertia
moment. When auto tuning mode 1 and interpolation mode is selected, the
result of auto tuning is automatically used.
(Refer to section 6.1.1)
In this case, it varies between 0 and 100.0.
When parameter No.PA08 is set to "
2" or " 3", this parameter can
be set manually.
Each
axis
7.0 Multiplier
( 1)
0
to
300.0
PB07 PG1 Model loop gain
Set the response gain up to the target position.
Increase the gain to improve track ability in response to the command.
When auto turning mode 1, 2 is selected, the result of auto turning is
automatically used.
When parameter No.PA08 is set to "
0" or " 3", this parameter can
be set manually.
Each
axis
24 rad/s 1
to
2000
PB08 PG2 Position loop gain
This parameter cannot be used in the speed control mode.
Used to set the gain of the position loop.
Set this parameter to increase the position response to level load disturbance.
Higher setting increases the response level but is liable to generate vibration
and/or noise.
When auto tuning mode 1, 2 and interpolation mode is selected, the result of
auto tuning is automatically used.
When parameter No.PA08 is set to "
3", this parameter can be set
manually.
Each
axis
37 rad/s 1
to
1000
PB09 VG2 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, 2 and interpolation mode is selected, the result of
auto tuning is automatically used.
When parameter No.PA08 is set to "
3", this parameter can be set
manually.
Each
axis
823 rad/s 20
to
50000
PB10 VIC 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, 2 and interpolation mode is selected, the result of
auto tuning is automatically used.
When parameter No.PA08 is set to "
3", this parameter can be set
manually.
Each
axis
33.7 ms 0.1
to
1000.0
PB11 VDC Speed differential compensation
Used to set the differential compensation.
When parameter No.PB24 is set to "
3 ", this parameter is made valid.
When parameter No.PA08 is set to " 0 ", this parameter is made valid by
instructions of controller.
Each
axis
980 0
to
1000
PB12 This parameter is not used. Do not change the value. 0
