I have a Bessie Rover 13 that has a old point to point control (NC400 Pro). I would like to convert it to Mach 3 so it will run standard G-code and do 3D carving. Right now its fitted with yaskawa cacr-sr02be12g-e servo packs. Anyone have any experience with driving them via Mach 3?


Here is the manuel for the drives...

i have two YASKAWA CACR-SR15BC  . and them are analog.
you should conver step/dir to -+10V .
Inexpensive way :use YAPSC10V (http://www.cnczone.com/forums/showthread.php?t=74532)

You can also run them with a DSPMC or Galil.

Converting a point to point machine to Mach3 control in not for the faint of heart. There is another thread here of someone converting a Busellato. Might want to search for it.

The encoders on the servo motors are UTOPH-81AVF. I cant seem to locate much info on them. Anyone know what they are and if they are compatible with one of the converters mentioned?

Manual won't come up for me - Can the drives be configurted for Step & Direction?

The newer Yaskawa Sigma series can be setup for Analog or Step&Direction. Omron sells a repackaged version of the Yaskawa drive that they call SmartStep that are stepper input only. I have also used Mitsubuishi drives that were step & Direction, but I preferred the Omron/Yaskawa drives. If you have the money one of these options might be easier to work with and you can get a local vendor to give you some assistance, depending on your level of electronics experience. It might cost a little more but you do buy access to their experience which might be what makes or breaks your project or your time frame for operation..

There are others out there - Automation Direct and others but I have zero experience with them.

I think the drives are speed control only. I would like to use the drives that are in there because they are already mounted and work great. Plenty of power. I think one of the analog to step/direction solutions is the way to go if the encoders will work with them.
