Speed integral
compensation
This is used to 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/or 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

differential
compensation
This is used to set the differential compensation.
To enable the setting value, turn on PC (proportional control).

amount
compensation
Set a viscous friction torque per percent to the servo motor rated speed.
When the response level is low, or when the torque is limited, the efficiency of the
parameter may be lower.
