PB07 PG1 Model loop gain
Set the response gain up to the target position.
As the gain is increased, the track ability in response to the command
is improved.
When executing the one-touch tuning, the result of the one-touch
tuning is automatically set in this parameter.
When auto turning mode 1 is selected, the result of auto turning is
automatically set in this parameter.

PB08 PG2 Position loop gain
Used to set the gain of the position loop.
Set this parameter to increase the position response level to load
disturbance. Higher setting increases the response level but is liable
to generate vibration and/or noise.
When auto tuning mode 1 and 2-gain adjustment mode are set, the
result of auto tuning is automatically set in this parameter.

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.
Higher setting increases the response level but is liable to generate
vibration and/or noise.
When auto tuning mode 1 and 2-gain adjustment mode are set, the
result of auto tuning is automatically set in this parameter.

PB10 VIC
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 and 2-gain adjustment mode are set, the
result of auto tuning is automatically set in this parameter.

PB11 VDC Speed differential compensation [Applied]
Used to set the differential compensation.
The set value is made valid when the proportion control (PC) is
switched on or the PID control is set in the PI-PID changing.

PB12 OVA Overshoot amount compensation [Applied]
Set the suppression ratio of the overshoot suppression control.
Set the suppression ratio for the friction torque in %.

%
POINT
This parameter can reduce the overshoot caused
by a device having large friction.
PB13 NH1 Machine resonance suppression filter 1
Set the notch frequency of the machine resonance suppression filter 1.
Executing one-touch tuning automatically changes this parameter.
When parameter No. PB01 is set to " 0", the setting of this
parameter is ignored.
