New Machine Build- Compumill Conversion

[mmc005]

I have an old Compumill 4000 with a Dynapath Delta 10 control on it. The control has a bad comm. board and I don't want to repair/replace the board due to the cost vs. capability of the control.
I want to pull that control off and replace it with a computer running Mach3 software. The machine has DC Servo motors with built in encoders, the motors are Baldors.
I know I need to replace the drives for the motors and have a breakout board for the computer, what else do I need to make this work?
I am looking at the Gecko G320 drives and the C11G interface card from CNC4PC.com. The instructions mention a power supply, do I need one? One for each drive or just one for all of the drives?
Any help with this would be greatly appriciated.
Thanks,
Dave

Dave,

Are the motors brush DC motors, or brushless motors?

If they're brush, you'll be fine. If they're brushless, you'll need to use a brushless servo drive.

You will need a power supply to power the drives. If you use the Gecko drive, you'll need a DC power supply that provides an appropriate amount of current that won't exceed what the three drives will use combined.

Matt,
Thank you for your response, I'm 90% sure the motors are brushless but I will find out for sure today. I will also find out the combined current usage for the motors and the voltage used.

Thanks again,

Dave
