This is almost a religious question, and many may avoid offering their own 
personal opinion.
My vote is for analog.  But in truth both can work equally well, and each have 
advantages and disadvantages.
Digital positioning, may be cheaper to implement, if the cost of "smart" servo 
drives is not in the equation.

Subject: [Emc-users] Servo - Velocity or Position mode

Hi

I have to upgrade and convert an old machine that was used to cut with 
gas. It uses some Panasonic MCDHT3520 servo drives.
These drives has a pulsed input for position and an analog +- 10v input 
for velocity mode.
The question is what mode is better to use with LCNC and Mesa cards, 
velocity or position?

I will use one of the Ethernet solutions from Mesa with a panel PC.
