Analog speed command offset:
Used to set the offset voltage of the analog speed command (VC).
When automatic VC offset is used, the automatically offset value is
set to this parameter.
The initial value is the value provided by the automatic VC offset
function before shipment at the VC-LG voltage of 0V.
S 29 VCO
Analog speed limit offset:
Used to set the offset voltage of the analog speed limit (VLA). When
automatic VC offset is used, the auto-matically offset value is set to
this parameter.
The initial value is the value provided by the automatic VC offset
function before shipment at the VLA-LG voltage of 0V.

34 GD2 Ratio of load inertia moment to servo motor inertia moment:
Used to set the ratio of the load inertia moment to the servo motor
shaft inertia moment. When auto tuning is selected, the result of
auto tuning is auto-matically set.

35 PG2 Position loop gain 2:
Used to set the gain of the position loop.
Set this parameter to increase the position response to level load
disturbance. Higher setting increases the response level but is liable
to generate vibration and/or noise.
When auto tuning is selected, the result of auto tuning is
automatically set.

36 VG1 Speed loop gain 1:
Normally this parameter setting need not be changed.
Higher setting increases the response level but is liable to generate
vibration and/or noise.
When auto tuning is selected, the result of auto tuning is
automatically set.

37 VG2 Speed loop gain 2:
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 is selected, the result of auto tuning is
automatically set.
