I've been running my little taig mill with Mach3 and enjoying it very much, but I recently wanted something just a bit bigger for woodworking projects. I bought this
http://i50.photobucket.com/albums/f348/father_torque/2b0b_3.jpg and I'm in the process of figuring out how to get it running.
The motors and drives are all Omron. They have a 400w motor on the x axis, 200 and 50 on the y and z. They are all 200V 3p drives. I spoke with the techs at Omron and they said that I could run the drives with regular household 208v, by running the 2 phases to two of the drives inputs and jumpering one of them to the third input. He said this would satisfy the internal voltage checks and allow the drive and motor to run albeit at 1/3 less power. Considering the size of the drives and motors and that I'm not going to be cutting metal with this I dont' see that as a problem.
My question is how do I go about interfacing between my PC and the Omron drives? I've read around enough to know I need some sort of breakout board, but I haven't seen an Omron specific one. I'm hoping that there isn't something different about the Omrons that would preclude me from running them in this fashion. I'd really like to use the existing motors and drives since everything is installed, wired up, and ready to go.
Any and all help would be greatly appreciated. In the event that you need them the motor model #s are U20030HA x axis, U40030HA-B y axis, U05030HA-B z axis. The drive #'s are R88D-UA12HA x axis, R88D-UA08HA y axis, and R88D-UA03HA z axis.
