Just upgraded from 2.7pre6 to 2.7pre7 and there's a few issues with the new hy_vfd stuff (I have been using the hy_vfd from, IIRC, S.Alford with 2.6 and 2.7 prior to 2.7pre7. I have a HY02D223B FWIW).
First the trivial but annoying or even a show-stopper for anyone not happy to read error messages and edit configs: <name>.rev has changed to <name>.reverse <name>.fwd has changed to <name>.forward <name>.modbus-ok has changed to <name>.hycomm-ok <name>.motor-pole-number seems to have gone. <name>.base-freq seems to have gone. These were all used in the example custompanel.xml examples I got with the 'original' hy_hfd from somewhere on that Internet... and 2.7pre7 obviously breaks that. Secondly an error in the hy_vfd man page: -V is shown as setting the max motor speed; that should be -S. Thirdly, and most weirdly, the speed of the spindle is not displayed on the VFD, and elsewhere, as commanded. Having tweaked all the above (and set the max motor speed to 24000 when I call hy_vfd with -S 24000) doing S1000 M3 makes the VFD display 800 RPM. S24000 shows 19200 RPM. However, my cheap'n'nasty tachometer seems to say that the actual spindle speed is the commanded one and not the one displayed. Still running at S1000, motion.spindle-speed-out shows 800RPM, <name>.Rott shows 800RPM but <name>.spindle-speed-fb shows 1000RPM. Here's a snapshot of all the hy_vfd pins while the spindle is commanded and actually running at 1000RPM. http://ruffle.me.uk/pics/misc/at1000rpm.png Any ideas? -- Regards, Russell -------------------------------------------------------------------- | Russell Brown | MAIL: [email protected] PHONE: 01780 471800 | | Lady Lodge Systems | WWW Work: http://www.lls.com | | Peterborough, England | WWW Play: http://www.ruffle.me.uk | -------------------------------------------------------------------- ------------------------------------------------------------------------------ _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
