ARROW 500 CT CONTROL

[rs1626]

I just bought a 500 machine at auction and am just about ready to hook power to it any thing I should know before turning it on I don't know if it ran or not the building had no power so i might have a piece of junk don't know yet

You will need an air supply, too, to turn it fully on. Without air, you can bring up the operators station but not the machine power.

I can power up and align my Arrow 500 with CT control without air.
I can jog the axes or move them with the MPG.
Can't run commands in MDI or auto without air, though.

I hooked power to it but I don't have 110v to the control power supply module any body know where that comes from ? any ideas what the problem might be?
Thanks

For starters what is your 3 phase supply voltage to the machine? 208-230-380-415-460. After knowing this you need to tap the transformer correctly based upon the incoming voltage. Be aware that the spindax drive if you have it requires the 380/460v so you have to go through the transformer.

my incoming voltage would be 230 do you have a dia. for the transformer i could not find one on the transformer its self i only have 220 at the spindax so i woul\d suspect that would be my problem

230 is confusing, I went through this myself.
I have to look at my transformer to describe it as the diagram I have does not exactly match.
I believe the 230v input taps are on the secondary side... where the ABC 230v comes out for the servo amps and the stepdown transformer that breaks out 120v (for the control) and 24v (or 12v, I forget) for other components (which explains why the control doesn't work yet).

Let me take a look (I'll take a picture of my transfromer for you).

Okay, here's the deal.
230v input goes on the bottom taps. In the photo the leads from the main switch are labeled as A, B, and C and go into the a1, b1, and c1 taps at the bottom of the transformer (on mine anyway).

I was having problems with the Spindax a while back. When I was troubleshooting I asked Rob Varney (at MAG) for ideas. I had mentioned that my 230v was closer to 240v. He told me to move the Spindax to the 380v taps and the Maxax drives to the 208 taps (which read 400v and 213v out of my transformer). He says the drives will tolerate under voltage, and over voltage was not good in his experience. I've been running it like this ever since (after I got the driver repaired at Emerson CT, that is).

Hope this helps.

ok i got the power figured out but machine will not boot up talked to mag i forget his name but he thinks it could be mem mod they will check it for $250.00 reload software if it can be done for $1000.00 or sell me a rebuilt one for $2400.00 i am thinking seriously about stripping control and servo drives off and retrofitting new control and drives

[scudzuki]

MAG can install a new Fagor 8070 or MachineMate for $18k. Their retrofit uses your existing amps and motors, though.

I got a quote to replace my CT with a Numatix control, around $26k installed or $19k if I install it myself. The Numatics (or Numeryx) control is pretty amazing, block processing time along the lines of 10 times faster than the closest competitor. Brainchild of the late Gil Hagiz (guy was a friggin' genius in motion control).

I have looked into EMC2 as well. It would take a hell of a lot of work to integrate one of those controllers but it is doable.

I have the software to reload the system if you are interested. Does the control come up at all? What error do you get?

no the monitor does not come on at all power light is on but nothing shows up on monitor
