I'm still a bit confused, but I think you mean that you want to control
the y-axis range (YRANGE) and the y-axis tick mark locations (YTICKV), i.e.:

plot, findgen(20) * 20, yrange=[0, 500], ytickv=findgen(11) * 50, $
yticks=10, yminor=5

This makes the y-axis range 0 to 500 and places a tickmark every 50. But
you could do something more exotic, e.g.:

plot, findgen(20) * 20, yrange=[0, 500], $
ytickv=[0., 100., 125., 150., 175., $
200., 250., 300., 400., 450., 500.], $
yticks=10, yminor=5
