Analog speed command offset
Used to set the offset voltage of the analog speed command (VC).
For example, if CCW rotation is provided by switching on forward
rotation start (ST1) with 0V applied to VC, set a negative value.
When automatic VC offset is used, the automatically offset value is
set to this parameter. (Refer to section 6.3)
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).
For example, if CCW rotation is provided by switching on forward
rotation selection (RS1) with 0V applied to VLA, set a negative value.
When automatic VC offset is used, the automatically offset value is
set to this parameter. (Refer to section 6.3)
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 mode 1 and interpolation
mode is selected, the result of auto tuning is automatically used.
(Refer to section 7.1.1)
In this case, it varies between 0 and 1000.

35 PG2 Position control 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 mode 1,2 and interpolation mode is selected, the
result of auto tuning is automatically used.

36 VG1 Speed control 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.

37 VG2 Speed control 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 mode 1
