FFC
Feed forward
gain Set the feed forward gain.
When the setting is 100%, the droop pulses during operation at constant speed will
be almost 0. When the super trace control is enabled, constant speed and uniform
acceleration/deceleration droop pulses will be almost 0. However, sudden
acceleration/deceleration will increase the overshoot. As a guideline, when the feed
forward gain setting is 100%, set 1 s or more for the acceleration time constant to
the rated speed.
Setting range: 0 to 100 0

PB06
GD2
Load to motor
inertia
ratio/load to
motor mass
ratio Set a load to motor inertia ratio or load to motor mass ratio.
Setting a value considerably different from the actual load moment of inertia or load
mass may cause an unexpected operation such as an overshoot.
The setting of this parameter will be automatic or manual depending on the setting of
[Pr. PA08]. Refer to the following table for details. When the parameter is set to
automatic, the value will vary between 0.00 and 100.00.
Setting range: 0.00 to 300.00 7.00

PG1
Model loop
gain Set the response gain 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 noise.
The setting of this parameter will be automatic or manual depending on the setting of
[Pr. PA08]. Refer to the following table for details.
Setting range: 1.0 to 2000.0 15.0

PG2
Position loop
gain 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 noise.
The setting of this parameter will be automatic or manual depending on the setting of
[Pr. PA08]. Refer to the following table for details.
Setting range: 1.0 to 2000.0 37.0
