Re: [CAD_CAM_EDM_DRO] High voltage servo controller

If those are dc servo motors then you could get it to run with Gecko G320's BUT the rapid speeds would be drastically reduced. I am guessing that the orignal machine was capable of 200 IPM with Geckos at 80V you could get 66 IPM. If the machine is for hobby work then that should be fine.
If you really want performance then look at the Granite servo amps, They will put out 200 volt at 10A. You'll have to slow down the accelration but they really look like nice drives and they work with both AC and DC servo motors see:

If the existing servo amps are not shot then you many want to look for something like the pixie boards that will take steps and direction and output a analog signal.

Hi,

I'm looking at a huge Cincinnati Milacron with Heidenhein control, unfortunately the control is totally ruined and needs replacement, the problem is the servos for the machine are huge and rated at 240V and 30A.
The machine is offered real cheap and would be a bargain if I could get it to work, so I was wondering if there is cheap way to control such motors using a PC, I used Geckos before but know their rating is 80V and 20A.

Regards,

Mina
