in the previous forum, you repeatedly referred to the ftp://ftp.deltacompsys.com/。

e.g. [plctalk.net/qanda/printthrea … 2533&pp=15](http://www.plctalk.net/qanda/printthread.php?t=42533&pp=15) ,there is “ftp://ftp.deltacompsys.com/public/NG...CM%20Proof.pdf”

I want to download the file,but needed user name and password。 I dont have that,so i cant access the ftp .

Peter can you help me? thanks a lot

The link is old and the site has moved.  
The first part of this link down to eq13 is the derivation of the VCCM equation. The middle part is turning the VCCM equation into a differential equation so the maximum acceleration rate can be calculated. The last part is the plotting with actual numbers. The numbers I used are from one of our hydraulic test systems.  
It takes a bit of study to work through all the math.
