Yes, it is possible to read the encoders of of some red caps with Linuxcnc. But not all red caps are the same, other than they are all 3 phase motors, (synchronous or asynchronous). Some have incremental encoders or some are serial and I'm pretty sure there are multiple kinds of serial encoders.
But what about the amps? All the ones I've worked with (from about 2002+) were connected to the Fanuc control via an optical serial bus. Are these all hopeless? On the surface they don't look to be any more help than an STMBL drive made from unobtanium. Todd Zuercher P.

The 4-line commutation signal is handled by a Pico hardware interface, or can be handled in software (the blcd component) and converted to standard Hall or position. Though possibly not as fast as you need for all applications. I think that the STMBL supports both red-cap and yellow-cap, but there is the usual problem with STMBL, availability. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
