	CV 5 is used to specify the motor voltage level at maximum speed. This value is a fraction of available voltage. When CV 5 equals 255 or 0, the full available voltage will be applied at full speed, a value of 128 will apply half of the available voltage at full speed, and so on. Changes to CV5 will automatically adjust the entire speed curve to linearly scale from 0 speed to the new full speed unless otherwise affected by [[{{NAMESPACE}}:CV_2\|CV 2]] and/or [[Diesel Version 5:CV 6\|CV 6]] .

	CV 5 should be the first CV programmed when setting up "speed limits" in locomotives. In a TCS decoder, [[{{NAMESPACE}}:CV_2\|CV 2]] and/or [[Diesel Version 5:CV 6\|CV 6]] do not need to be modified before modifying CV 5; however, if you have already set values in [[{{NAMESPACE}}:CV_2\|CV 2]] and [[Diesel Version 5:CV 6\|CV 6]], this must be taken into account first before programming CV 5.
