Peter,
It looks as if there has been a problem with the feeds and someone has uncoupled the external linkages in the mistaken belief that is the place to start looking for a solution. You can easily test the feeds by manually operating the feed levers on the saddle (ie the ones that would be moved if the linkages were in place). They will be quite hard to move by hand, but should click into engagement (you may have to turn the feed handwheels a bit to line up the internal dog clutches so the feeds can engage). If the feeds do not work, the most likely explanation is that the shear pin is broken. If you make another shear pin yourself be sure (as mentioned) to use soft steel, and make sure the shear pin does not extent through to the other side. It must be only in single shear - not double shear.
Your FP1 looks to be in nice condition, and hopefully the saddle has been lubricated with oil, not grease!
Re the motor, there was a thread somewhere in which the possibility of rewiring these pole changing motors to a 'double delta' configuration for 240V was explored, but I was not that adventurous. Also I wanted to keep the original face-mount Siemens motor, so had my FP1 motor rewound to 240v and am now finalising the VFD setup.
With a foot mounted motor as on your FP1 the easy way is to get a standard foot-mounted 3 phase motor (preferably running at the same speed as the low speed of your original motor), wire the motor in delta, and use the VFD to give you the high motor speed when needed.
Enjoy!
Cheers,
Bill
