VSST allows users to do two things. First, and this is the most common, it lets users manually change the RPM during the threading cycle. This function is enabled either by turning it on by parameter (for continuous use) or by M-code in the program (for occasional use). Secondly, VSST allows users to change the speed, in the program, for each threading pass – a functionality not often used, but available. Most users set the parameter and vary the speed manually, so in the majority of cases there is no programming required.
