Load to motor
inertia ratio
This is used to set the load to motor inertia ratio.
The setting of the parameter will be the automatic setting or manual setting
depending on the [Pr. PA08] setting. Refer to the following table for details.
When the parameter is automatic setting, the value will vary between 0.00 and
100.00.
Setting range: 0.00 to 300.00

PB07
PG1
Model loop gain
Set the response gain up to the target position.
Increasing the setting value will also increase the response level to the position
command 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 following table for details.
Setting range: 1.0 to 2000.0

Position loop
gain
This is used to set the gain of the position loop.
Set this parameter to increase the position response to level load disturbance.
Increasing the setting value will also increase the response level to the load
disturbance 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 following table for details.

PB09
VG2
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.
