This does an absolute move and will always go to the same "absolute" position.]]></content:encoded>

                        <content:encoded><![CDATA[The other thing I've noticed in LabVIEW is if I slow down the execution, it shows the down displacement and acceleration as D=-2512 and A=*, while the up displacement and acceleration show as D=2512 and A=1*.  The program is set up to move down first.  Could this be part of the problem or is it just the way LabVIEW labels it?  The acceleration for both is read off the same string and it's set at 10000.]]></content:encoded>

                        <content:encoded><![CDATA[Hi,

I'm trying to create a cyclic program in Labview using SM1720M version 4.15b.  I have a program that mostly works, but the down displacement is 2-3 motor counts shorter than the up displacement.  I'm sending the commands using D,A,V,and G.  I tried using TWAIT, but it did not seem to make a difference. 

Sorry this is reposted, but I couldn't reply to my previous post and then it seemed to disappear all together.
Any help would be greatly appreciated!]]></content:encoded>
