Technically you probably could. It's an ugly, ugly thing though. Your -6044-H010 drive is a Model 12 analog drive. The -6055-H108 is a Model 8 digital drive. The Model 8 is lower HP than a Model 12. There are also different RPM versions (4500 and 6000) of both drives. You would have to have those matched or possibly have the Model 8 be a 6000 RPM. With enough parameter changes you could probably get the Model 8 drive to not overspeed your Model 12 motor if your Model 8 drive was the 6000 RPM version and your Model 12 motor was the 4500 RPM version. The next thing is you will be how to deal with the reduced HP. I do not have the manual with the HP specs handy to tell you the difference absolutely, but it will probably be something like 25-30% lower. Another thing you would need to sort out would be a set of drive and control parameters.

I second using T.I.E. as that is who I use, they aren't the cheapest but I have found they are the most reliable.

I went down to my shop to get the manual with the drive specs.

Model 8 is 10HP cont. 15HP int.
Model 12 is 15HP cont. 20HP int.

I visited TIE in July. Heck of a place. Aisles upon aisles of Fanuc drives and motors. Really friendly folk, too. Took me through a tour of the whole place.

The analog drives are pretty simple. I'm not a rocket surgeon, but I was able to download the Fanuc analog drive manual for free and use a ohmeter and a O-scope to repair mine.

I've actually repaired the same drive 3 times. Top board twice and IGBT's

By far the most difficult part is keeping track of all the unlabeled white wires when you replace the IGBT's. I used a fine tip sharpie to label all the wires and terminals and took lots of pictures.

I blew the IGBT's apart in my big VMC's Digital drive and got lucky. $300 in new IGBT's and it works better than it ever did. A lot better than a $5000 repair bill and shipping a small refrigerator across the country.

I had a slew of problems related to higher incoming voltage than a realized.
