  1. So I got to the bottom of it tonight. I knew some time away from it would be good...... It turns out that whoever wired the machine initially had not made a good ground connection on the 600Vac machine feed. The 50Vac was induced voltage through the ground whenever the drive was powered up. Thanks for the help guys.  
  2. Thanks for your help.I need to step back from it a bit just to see if I missed something simple. Everything points to the Drive..
  3. Might have to call Rockwell on this one..... As much fun as that sounds !! 
  4. I've isolated the drive completely. It's sitting on an absorbent pad in the bottom of the panel with the ground wires disconnected from the backplane. When I measure between the base frame of the drive to my ground in the panel I get the 50Vac? If I pull the fuse block out that feeds the drive the Voltage goes away. I even tried disconnecting the feed wires from the drive and pushing the fuses back in and I get nothing to ground. Only when the drive is powered???
  5. The Motor was my first thought but I disconnected the motor feed wires right at the drive so it's eliminated from the picture. Nothing connected to the drive but the 3 Feed wires in from a fuse block. Just as a test I unhooked the incoming ground wire from the main feed to the panel and sure enough I get 50VAC from the base of the drive to the incoming ground wire! Got me stumped..... 
  6. I'm not even sure how to start this one off but We have a polishing unit that uses a PF70 to drive a belt motor. This machine has some suction ducting that connects to it. We recently had the duct disconnected to do some work on it and with the machine powered up one of the guys felt a little buzz when he touched the duct and the panel door. I checked and sure enough there is 50VAC from the ground lug on the panel to the frame of the dust collector? I've isolated it down to the PF70 base that is putting out the voltage to the ground in our machine through the base of the drive. Anyone else ever seen this before? When we hook up the duct the voltage goes away? We have a spare unit and tried swapping it out but we get almost the same voltage to ground? This only happens when we power up the drive.
  7. 50 views and nobody has any info on this? Is it something I said or the way I said it? :)
  8. I am looking for information on monitoring a user by their password. I have a panelview 550 with a micrologix 1500. With the panelbuilder software I can see in security settings the option to put in a Current User tag for the protected screen. When I try to put a tag in I'm not getting the result I expect. I'd like to be able know which operator is accessing the secured screen and changing values. Any info would be appreciated. Thanks
  9. I am having an issue with a network that I have 4 Identical machines on. I'm using RSLinx 2.59.02. Each machine has a contrologix plc, Powerflex70 drive and a panelview 1000 all connected by ethernet. I have all 4 machines on a switch connected to a machine server. When I use my laptop to view the network from my bench I see everything in the tree except for 3 of the 4 PF70's? 1 shows up fine but the other 3 show up as unrecognised devices. They are all identical machines with the same settings? I can ping all of them at the command prompt so I know they are there but Linx won't recognise them? Any ideas? Thanks in advance
  10. Thanks guys. I knew I came to the right place. I'll try that.
  11. I was wondering if anyone has installed a remote display for a PowerFlex 70 unit. What we are looking for is a digital display to indicate what speed a conveyor is running at, from a distance of a 20 or 30 ft. The HIM display is just not visible enough. Any help would be great. Thanks
  12. Thanks guys. Great info. I think I will go with the FT View approach for the Panelview. That way I'll have a good copy of it on my PC for future changes.
  13. Thanks for the quick reply. So what I'm thinking is to change the PLC first.. then the Panelview IP and then with FT Studio go into the communications (with RSlinx)and change the Design Local settings to the new PLC IP address and copy it to the runtime settings and download that back into the panelview. Oh yeah and then change the PF70 IP also. Sound right?
  14. Hi. We have a system made up of a PowerFlex 70 , a Panelview Plus 1000 and a 1768-L43 Compactlogix Plc. IT would like to have this machine monitored on our local ethernet and this would require changing the IP address' on all 3 components. I don't believe it is as simple as just changing them individually.... IE: the panelview tag search locations? I know how to change them but I'm worried about the communications between the PLC and the Panelview after I do. This is going to be done during production as we need this unit running 24/7. ( Of Course) Any help would be great. Thanks
  15. So I tried that.... No Luck. I think I've tried every combination that is offered on this C300. Is there any way of seeing that your actually online with a Micrologix PLC? I can't seem to find any screen or setting that actually shows a plc connected??? Thanks
