PB07 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 [Pr. PA08] is set to "_ _ _ 0" or "_ _ _ 3" , this
parameter can be set manually.
24 PB07 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 noise.
For the vibration suppression control tuning mode, the
setting range of [Pr. PB07] is limited. Refer to "MR-
J4W2-_B servo amplifier instruction manual" for details.
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.
Pr. PA08 This parameter
_ _ _ 0 (2 gain adjustment mode 1
(interpolation mode)) Manual setting
_ _ _ 1 (Auto tuning mode 1) Automatic setting
_ _ _ 2 (Auto tuning mode 2)
_ _ _ 3 (Manual mode) Manual setting
_ _ _ 4 (2 gain adjustment mode 2)

PB08 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 [Pr. PA08] is set to " _ _ _ 3", this parameter can
be set manually.
37 PB08 Position loop gain
Set a 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 the parameter will be the automatic setting
or manual setting depending on the [Pr. PA08] setting.
Refer to the following table for details.
Pr. PA08 This parameter
_ _ _ 0 (2 gain adjustment mode 1
(interpolation mode)) Automatic setting
_ _ _ 1 (Auto tuning mode 1)
_ _ _ 2 (Auto tuning mode 2)
_ _ _ 3 (Manual mode) Manual setting
_ _ _ 4 (2 gain adjustment mode 2) Automatic setting
37.0
PB09 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 [Pr. PA08] is set to " _ _ _ 3", this parameter can
be set manually.
823 PB09 Speed loop gain
Set a 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 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.
823
PB10 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 [Pr. PA08] is set to " _ _ _ 3", this parameter can
be set manually.
33.7 PB10 Speed integral compensation
Set an integral time constant of the speed loop.
Decreasing the setting value will increase the response
level but will be liable to generate vibration and 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. 33.7
PB11 Speed differential compensation
Used to set the differential compensation.
When [Pr. PB24] is set to "_ _ 3_" , this parameter is
made valid. When [Pr. PB24] is set to "_ _ 0_", this
parameter is made valid by instructions of controller.
980 PB11 Speed differential compensation
Set a differential compensation.
To enable the parameter, select "Continuous PID control
enabled (_ _ 3 _)" of "PI-PID switching control selection"
in [Pr. PB24].
