==NMRA CV 6 - Vmid (Mid Volts)==<br />
CV 6 specifies the voltage drive level at the middle speed step (63/126). CV 6 is used to generate a performance curve in the decoder that translate speed step values into motor voltage drive levels, and is specified as a fraction of available rectified supply voltage. CV 6 is used to "slide" the curve in one direction or another, where the value in CV 6 will adjust the curve for greater or less sensitivity in the later half of the speed curve. CV 6 should be left unmodified when setting up "speed limits" in decoders unless you are unsatisfied with the default speed curve calculation. <br />
<br />
''NOTE: CV6 will not be "in use" ''as part of the speed curve calculation'' if programmed with a value of 0 or 128''.<br />
<br />
CV 6 is used in conjunction with [[{{NAMESPACE}}:CV_2|CV 2]] and [[{{NAMESPACE}}:CV_5|CV 5]] as part of the [[{{NAMESPACE}}:3_Point_Speed_Curves_Feature|3 Point Speed Curves feature]].<br />
<br />
<br />
From S-9.2.2 of the NMRA Standards and Recommended Practices:<br />
<br />
''"Vmid specifies the voltage drive level at the middle speed step. Vmid is used to generate a performance curve in the decoder that translate speed step values into motor voltage drive levels and is specified as a fraction of available rectified supply voltage. Values of 0 or 128 shall indicate that Vmid is not used in the calculation of the speed table."''<br />
