AC or Dc

[Dem1]

Hi all,
Am going to change out some old servo motors on an esab plasma table
I see lots of different places to purchase, and different makes,
But what would be the most popular
AC or DC powered,
I have read DC is simpler to hook up,??


I have mach3
So thinking I might stick with it,
Not a 100% sure just yet on this,
I have small table running on steppers with mach3, and it will lose a step now and then,

If anybody would know of any other good controller system, that would be better than SHEETCAM and MACH 3 all round,
am all ears,

It depends on the present condition of the DC servo's, brushes, comm, etc.
What make?, do they have encoders mounted to them?
Also what drives are fitted, and type of servo drive command signal?

There old school on tacho,s


I would prefer to change the motors when am going this far,
And try and simplify it, if am going to stay with mach3,
The gearboxes are still in good condition,
If I could find a company to purchase the complete kit from, ie servo motors, drivers and and whatever board is needed to link Mach to the drivers,

Then DMM would be your best choice then, which are Ac servos

AC is more popular now.

yep i would go with AC too. Its definitive more popular these days. Plus its not really harder to hook up.

I recently had to retrofit an old machine, but used Mach4 and the CSMIO-IP/A. The configuration was very straight forward. I got the axis to run in less than 30 minutes.
