Re in circuit ESR meter: If you have a breadboard and an hour, this does pretty much the same thing with £10 worth of parts, less if you have a junk box: http://members.shaw.ca/SWSTUFF/esrmeter.html Uses about 250mV so doesnt activate active devices, and works on charged caps. Also open hardware design, which is nice. Id definately check your mains supply, under normal load and without anything else on. You can get simple 3 phase testers quite cheaply in case you dont have a 4 channel scope. I dont know much about Fanuc stuff, but its posssible its a commutation track issue, they use a 4 bit track numbered 1 2 4 8, and its possible that the drive is seeing an illegal state. Maybe worth checking encoder/hall wiring, encoder etc. Some useful discussion here: http://www.cnczone.com/forums/fanuc/80754-fanuc-encoder-lines-c1-c2-c4-c8.html JHC -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTxlxBAAoJEDzttOCNrFucj7QH/0ERMZXO48Eu2XEP0eFmzbAP e50z3GBXh+tqBx/3SuT/4ar1zwJflR+Z6jtoXOoUcy36dcqDB1JMVw1rH8UlOsbA hbpMXXvlxI9ZJ9v6DNIsvbf4+pNBah7GB0ByYF6MclENeaY7zF5nitwB7PmRxQwY Ze5NnW06epvy596ma5XLR8X66g68ik37sYRbgrOhY6uH2SCKwcjYS2W4nSqgjkwY 1MG+RtNipl1w0E7on0kXiUcg1XR5B74FnTF5eukUm55i/4PHJP89xNkm+Bn6o3G+ KUgCE7lH43iUfQjifYsSgePr6Q7cUspu8dC12Q8DmVXhzFQl5Ocbv8jwiZZNSYs= =nE8q -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
