I fear the control has too many checks to the outside world to trick it into thinking everything is functional to run the spindle from a near dead closed loop control. You might get all the E-stop contacts jumpered and find some other input in conflict, since the control cannot track or null out the servos, tach and encoders.

If the machine has a Yaskawa spindle drive, you may be able to jumper out the E-stop there and then use its display to run the spindle motor. You will need a manual for the spindle drive and you MUST be very careful NOT to change any of the settings in the drive parameters. It would be wise to learn how the drive works anyways and record all of the settings for your records. Yaskawa should have the manual on line or you could make an email request in PDF format. These are very complex manuals to which only about 30% may apply to your particular application.

This is not for the weekend warrior, so read and comprehend as much as you can, to feel confident before you start and make notes of any changes in wiring etc.

Make sure all the other wires you have disconnected are isolated and secure before powering up.

Hi DC..

Thanks for the info. I fear that you are correct as far as tricking the control. But I wasn't sure so I figured I'd ask.

IIRC, my machine has a Custom Servos 15hp 10,000 rpm spindle motor. There is a big black box in the back of the machine that controls the spindle motor. Is has a serial connection to the control PC.

I may be a little fuzzy on the spindle motor manufacturer, I'll double check when I get home.

Thanks,
Michael

If this is a Centurion 5(VI) then the black box is the PC motherboard and card cage. The spindle drive would not be in there. It should be a large plastic case with a small LCD display/keyboard on it. It is not normally serial, but connected via the CPC(circular plasctic connector) cannon plugs on the side of the black box. Typically an enable line, an analog output to control spindle drive and a few relay dry contacts. If yours is different, I can't be of much help there.

Centurion 4's(IV), I know little to nothing about. Other than they are odd ball old school stuff prior to the PC based acro loop control.

Hi DC..

There is actually *2* "black boxes" in the back of the machine. One is the PC and card cage, the other is the spindle controller. There is definitely a serial cable between the spindle controller and the PC.

I will take a picture tonight when I get home if I get a chance.
