What are the LabView steps?

[Matthew T]

I have a linear stage with length of 250 mm. The screw pitch is 5 mm/rev and there are 200 full steps/rev and 250 microsteps/full step. This gives the total number of steps:

250 mm / 5 mm/rev = 50 rev

50 rev * 200 full steps / rev = 10000 full steps

10000 full steps * 250 microsteps/full steps = 2 500 000 microsteps

However, when I use MAX to find the limits of the stage I get a range from -3 000 000 to 3 000 000.

What are the LabView steps here? Am I missing something?

Now I noticed that the screw pitch of my stage was actually 2 mm/rev. Sorry, for bothering.
