Hey everyone, I just got the wires replaced inside the tachogenerator on one of my servo motors (cat chewed them in half while it was sitting out where i was working), and I think it's time to get everything hooked up and see what happens when i feed the amp a Vcmd.
My first hangup is the wiring for the power supply. I guess it's not a hangup, but more of a double-check. On the inputs to the suppley, the terminals are labeled R, S, T, E, COM, PON, and PAL. R, S, T, and are the 3 phase input and ground. The mill's manual specs say there is a "Power ON signal", "contact opened on normal power continuity" and "Power error", "contact short-circuited on pegenerative abnormality or open collector TrON" So after reading this, I'd guess that PON goes float during normal operation, and is pulled to ground by relay contact when theres problem? and for PAL, I'd guess that... well... the same thing? Is it me not comprehending what little info I have? I'm hoping that for testing, I wont need to use these at all. If anyone knows where to find sanyo denki BL-super manuals or datasheets or any info at all, I'll be extremely grateful if you share. I've googled and all i can find is people selling them. the part numbers are: Power supply: BP060RXB Amps, X+Y: 27BA030FXTH1 Amp, Z: 27BA050FXTH2 Motors X,Y:20BM090MXP42 as far as whether or not the supply will run on single phase power, the 3 phases run from the breaker to a rectifier, http://www.datasheetcatalog.com/datasheets_pdf/R/M/3/0/RM30TA-H.shtml so i think it would be fine running single phase. I'm still trying to figure out where the PON and PAL wires run, but there isnt much room to see in there, let alone poke my fat fingers around. Dont worry, the capacitor is fully discharged :) The machine was built late 1987, if this helps any at all. I really dont know how i can show my appreciation for all the help you guys give, and I cant wait till i can afford to go to fest and meet some of you. If I could bring my machine, I would but it's WAYYY too big for that, but the servos and amps will fit in the trunk of the neon :D ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
