I finally got around to posting a couple of videos and a few more pictures of the Harris Mfg. job that Basem and I recently did in Fresno. The machine was an Amada COMA that had been previously retrofitted with a Punch Wizard PC based control. As you can see from the still pics, this machine had Fanuc's old 10L servo motors on it which are liquid cooled (coolant inside the armature which circulates to a heat exchanger on the shaft end). I took the chance of using a smaller motor than this, mainly because the breaker for the whole drive was only 20 Amps. The motor we put on was the largest one Yaskawa makes with the 10L flange and 35MM shaft.
They worked great.
This video is both axes at 1000 IPM:

This one is of a heavy part (60 lbs?) at about 700 IPM. The motor is loafing:

Here's the old motor, all taped up from years of trouble:
We mounted the new drives where to old ones were:
Basem mounts the new motor, same mount, same shaft:
The new drives are VERY easy to integrate. Auto tuning is amazing and actually works.
Keep looking for opportunities for these drives.
