At high rpm a resolver may make more sense ... and more $$. Depends. ??

Gene, do you have a part number for your high RPM Omron encoder? Maybe I can
snag one...

If you want spindle positioning (for more accurate probing of
alignment for tool changes for examples) you'll need the encoder to
follow the position at all speeds. Are there high RPM capable absolute
encoders at a reasonable price?
The one I have on the rear end of that 1hp motor, an Omron 1000 ppr, cost me
$21 on fleabay 6 years ago. Its a differential model I'm converting to ttl
in a pair of rs485 to ttl interfaces that cost about $2 each, driving a 5i25
card. NO optics in that path. Absolute it is not, but if the encoder tracks,
who cares.
