12 Load to motor inertia ratio
(Load inertia ratio)
Used to set the load inertia (moment of inertia) ratio to the
servo motor shaft inertia moment. When auto tuning mode 1
or interpolation mode is selected, the result of auto tuning is
automatically used.
7.0
PB06 Load to motor inertia ratio
Used to set load to motor inertia ratio.
This parameter can be set either automatically or
manually depending on the [Pr. PA08] setting
.
Refer to
t
he
following table for details. When this parameter is set
automatically, the value varies between 0.00 and 100.00.

13 Position loop gain 1.
Used to set the gain of the position loop.
Increase the gain to improve track ability in response to the
position command.
When auto tuning mode 1 or 2 is selected, the auto tuning
result is automatically used.
7 kW or
less: 35
11 kW
or more:
19
PB07 Model loop gain
Used to set the response gain till the set position.
If the setting value is increased, traceability for position
command is improved. However, if the setting value is too
large, it tends to vibrate or oscillate.
This parameter can be set either automatically or
manually depending on the [Pr. PA08] setting.
Refer to
the following table for details.

Loop
Gain
Normally, it is unnecessary to change this parameter. Higher
setting increases the response level but is liable to generate
vibration and/or noise.
When auto tuning mode 1 or 2 and manual mode 1 are
selected, the auto tuning result is automatically used.
7 kW or
less:
177
11 kW

No corresponding parameter
15 Position loop gain 2.
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 or 2, manual mode 1, and
interpolation mode are selected, the auto tuning result is
automatically used.
7 kW or
less: 35
11 kW
or more:
19
PB08 Position loop gain
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 for load
disturbance, but if the setting value is too large, vibration
and noise are more likely to occur.
This parameter can be set either automatically or
manually depending on the [Pr.PA08] setting. Refer to the
following table for details.

16 Speed loop gain 2.
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 or 2 and interpolation mode are
selected, the auto tuning result is automatically used.

PB09 Speed
loop
gain
Used to set the gain of the speed loop.
Set this parameter when vibration occurs on machines of
low rigidity or large backlash. Higher setting increases the
response level, but if the setting value is too large,
vibration and noise are more likely to occur.
This parameter can be set either automatically or
manually depending on the [Pr.PA08] setting. Refer to [Pr.
PB08] table for details.
823
17 Speed
integral
compensation
Set the time constant for integral compensation.
When auto tuning mode 1 or 2 and interpolation mode are
selected, the auto tuning result is automatically used.
7 kW or
less: 48
11 kW
or
more:
91
PB10 Speed
integral
compensation
Used to set the integral time constant of the speed loop.
Decreasing the setting value will increase the response
level, but vibration and noise are more likely to occur.
This parameter can be set either automatically or
manually depending on the [Pr.PA08] setting. Refer to [Pr.
PB08] table for details.
