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 noise.
For the vibration suppression control tuning mode, the setting range of [Pr. PB07] is
limited. Refer to section 7.1.5 (4) 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.
Setting range: 1.0 to 2000.0

PB08
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 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

PB09
VG2
Speed loop
gain
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 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.
Setting range: 20 to 65535
823
[rad/s]
PB10
VIC
Speed
integral
compensation
Set the 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.
Setting range: 0.1 to 1000.0
33.7

differential
compensation
Set the differential compensation.
To enable the setting value, turn on PC (proportional control).
