6.8.19 Reference speed setting (network input config SNVT_rpm nciNmlSpeed)
Set the speed used as the reference of "speed adjustment (nviDrvSpeedScale)" (Refer to page 49), "speed
monitor (nvoDrvSpeed)" (Refer to page 50), "maximum speed (nciMaxSpeed)" (Refer to page 99) and
"minimum speed (nciMinSpeed)" (Refer to page 99).
