FFC
Feed forward
gain Set the feed forward gain.
When the setting is 100%, the droop pulses during operation at constant speed are
nearly zero. However, sudden acceleration/deceleration will increase the overshoot.
As a guideline, when the feed forward gain setting is 100%, set 1 s or more as the
acceleration time constant up to the rated speed.
Setting range: 0 to 100 0

PB06
GD2
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 7.00

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 15.0

PB08
PG2
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.
Setting range: 1.0 to 2000.0 37.0
