what is this
I can't believe the children in this forum. i thought this was a stand up place.
and pierre, please, once again, scroll up and read my previous post.
to update those who actually was interested in the situation, the problem was obviously communication related. the mistubishi VFD are absolute garbage. 2 of the 4 had bad communication cards on them, setting parameters is a joke (unless of course you have the attachable keyboard) and one of the 2 the whole drive was trash. While talking w/ support for these i'm being told i needed to put it in network mode, after spending several minutes (another guy as well) scrolling the manual for this mysterious "network mode" i gave up. There is no such thing in this manual. I finally tried setting the parameter (79 for the poor folks who may have to deal with these one day) to 0 for pc communication ( i believe is what it was called ) and it would error out. After trying to repeatedly, and i mean repeatedly to get this parameter set, or the drive into PU mode without it erroring, i finally gave up. While i was pacing just ready to kick the hell out of this panel and tell them they're screwed (customer was due in from canada in about 8 hours to see it operating) the panel builder was screwing around with them and accidentally got parameter 79 set to 0. I'LL BE DAMNED. He had to change it to 3 and then back to 0. These things were very shaky however, you couldn't reset the error clear, or the parameter clear w/o being in PU mode. You couldn't get into PU mode until you set parameter 79 to 0. Give me a break.
So we get it talking, start tweaking PID's (and all the fun that entails) then ready to start it. At this point i'm exhausted and must go home (as i'm not being paid to be there anyway so time for other to earn their keep) and get some sleep, be back in a few hours before customers get there. On my way out there i call and sure enough, the VFD's lost communication. "ok then, i'm going back to bed, bye"
It was a wonderful evening, and the guy i flew up here and is billing me $120/hr to be there, hasn't lifted a finger yet. I love this work, does it get any better?
If anybody would like to compare the Mistubishi program to RsLogix in a "which is better discussion" PLEASE message me, that is the most worthless software i've ever used, and i used windows millenium for a day one time. Are you kidding me after focing a bit you have to go back throught he drop down box (after it shut) and find the bit and force it off? is this a joke? mitsubishi> "lets see how bad you can screw your machine up by it not being ready to force this bit on" (yes the project manager had the plc hooked up live and controlling the oven, and of course the oven isn't even finished being assembled by this point)
anybody needing help with a job, don't ask me if it doesn't involve GE Fanuc or AB.
Thanks alot
