"Slot" is a term I expect to be associated with a toolchanger on a mill. Never heard it used in that context before. Simpson36 stated that Mach is not controlling the spindle speed, and that's what I read. Mach needs to now the angular position of the spindle as well as z axis position to single point thread. If it cannot control but can monitor the spindle speed then it must adjust the axis feedrate to compensate for any mismatch in spindle speed (and the resulting angular mis-positioning). Sorry to muddy the waters.
My use of the work "expect" was related to what appeared to be a misunderstanding of the technology on your part... as it turns out I'm the one who has no idea what I'm talking about.
