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 this parameter will be automatic or manual depending on the setting
of [Pr. PA08]. 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 with large
backlash. Increasing the setting value will also increase the response level but will
be liable to generate vibration and noise.
The setting of this parameter will be automatic or manual depending on the setting
of [Pr. PA08]. Refer to the table of [Pr. PB08] for details.
Setting range: 20 to 65535
823
[rad/s]
PB10
VIC
Speed
integral
compensatio
n
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 this parameter will be automatic or manual depending on the setting
of [Pr. PA08]. Refer to the table of [Pr. PB08] for details.
Setting range: 0.1 to 1000.0
33.7
[ms]
PB11
VDC
Speed
differential
compensatio
n
Set the differential compensation.
To enable the parameter at all times, select "Continuous PID control enabled (_ _ 3
_)" of "PI-PID switching control selection" in [Pr. PB24].
To enable it, turn on PC (Proportional control) or PID switching signal (C_PC) from
upper side.
Setting range: 0 to 1000
980
PB12
OVA
Overshoot
amount
compensatio
n
Set a dynamic friction torque in percentage to the rated torque at servo motor rated
speed. Or, set a percentage of dynamic friction force against the continuous thrust
at linear servo motor rated speed.
When the response level is low or when the torque/thrust is limited, the efficiency of
the parameter may be lower.
Setting range: 0 to 100
0

PB13
NH1
Machine
resonance
suppression
filter 1
Set the notch frequency of the machine resonance suppression filter 1.
When "Filter tuning mode selection" is set to "Automatic setting (_ _ _ 1)" in [Pr.
PB01], this parameter will be adjusted automatically by adaptive tuning.
When "Filter tuning mode selection" is set to "Manual setting (_ _ _ 2)" in [Pr.
PB01], the setting value will be enabled.
Setting range: 10 to 4500
