(Note) Set to "0" for bits with no particular description.
Not used. Set to "0".
If the noise is bothersome at high speed during rapid traverse, etc, lower
the speed loop gain.
Set the speed at which the speed loop gain changes, and use this with
SV006 (VGN2). (Refer to SV006)
When not using, set to "0".
Explanation
When 100% is set, the voltage equivalent to the logical
non-energized time will be compensated.
When "0" is set, a 100% compensation will be performed.
Adjust in increments of 10% from the default value 100%.
If increased too much, vibration or vibration noise may be
generated.
Normally set to "0".
Use this in combination with SV040 and the high order 8bits
of SV045.
