[Pr. PB08_Position control gain (PG2)]
Set the gain of the position loop.
Set this servo parameter when increasing the position responsiveness to level load disturbance.
Increasing the setting value improves responsiveness to the load disturbance, but increasing the value too much raises the
likelihood of vibration and noise.
The setting of this servo parameter will be automatic or manual depending on the setting value of [Pr. PA08.0 Gain adjustment
mode selection]. Refer to the following table for details.
[Pr. PB09_Speed control gain (VG2)]
Set the gain of the speed loop.
Set this servo parameter when vibration occurs on machines with low rigidity or with large backlash. Increasing the setting
value improves responsiveness, but increasing the value too much raises the likelihood of vibration and noise.
The setting of this servo parameter will be automatic or manual depending on the setting value of [Pr. PA08.0 Gain adjustment
mode selection]. Refer to the following for details.
Page 39 [Pr. PB08_Position control gain (PG2)]
[Pr. PB10_Speed integral compensation (VIC)]
Set the integral time constant of the speed loop.
Decreasing the setting value improves responsiveness, but raises the likelihood of vibration and noise.
The setting of this servo parameter will be automatic or manual depending on the setting value of [Pr. PA08.0 Gain adjustment
mode selection]. Refer to the following for details.
