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.

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.

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.
