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.

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.  

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..

Might have to call Rockwell on this one..... As much fun as that sounds !! 

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???

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..... 

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

50 views and nobody has any info on this? Is it something I said or the way I said it? :)

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

Thanks guys. I knew I came to the right place. I'll try that.

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

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

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.

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?

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

I've started on a simple little project for testing purposes. I have a Micrologix 1500 LRC and I'm trying to connect a Panelview C300 to it. I can get online to the 1500 with RSLinx. I can get online with the C300 using the usb link and the onboad software and create screens. Where I'm having an issue is with the comms between the 1500 and the C300. I have both setup for DF1 with the same settings and I'm plugged into the Serial com port of the C300 using a 1761-cbl-pm02 cable to the 1500. I read somewhere in the manual that it should communicate on that cable. When I look at my project and Validate Communications it comes back with no errors. Is there an easy way to tell if the plc is communicating with the C300? Sorry. It's the first time I've used this type of Panelview. The project doesn't warrant a "Real" panelview. Thanks

Anybody???

Here are 2 pics of the Communications setup on both C300 and Micrologix 1500 LRP

Quick question. Does anyone know if there is a parameter setting or a way to get a PowerFlex 70 drive to power up to Manual mode instead of Auto mode? When we have a power outage it automatically starts up in Auto mode. Any help would be great. Thanks

Sorry. Forgot to mention that we are running it from the HIM plugged into the front of the unit. There are no terminal speed commands other than the default speeds. All conveyor speed changes are made from the HIM. I read that section of the manual ..at the end of that section it says : "2. If a HIM has manual control and power is removed from the drive, the drive will return to Auto mode when power is reapplied."

Thanks Bob. Once again you saved me tons of time looking. Keep doing what you do.

I'm looking at probably 150 or 200 meny items (Model Numbers) I don't even think an MLX1100 can handle that many String files(I keep getting errors of words more than 4K)...let alone the 150 lines of programming. It was the PLC that was handed to me by Engineering....I've only worked with Sl/c , Contrologix and MLX1500. This one was new to me...I'm thinking we will be substituting it. Thanks for your help.

Hello Does anyone have any experience with creating a list of data on a Micrologix 1100 and Showing that list on a Panelview 1000? I've created the ST bits and I can see them all on the Panelview screen I've created but when I try to show just one that I've picked from the menu I can't get it to copy to that ST bit to a specific ST bit I guess what I'm asking is ...Is it possible to choose a menu item from a list on the panelview and show it as a string display on another page? I've seen it done on a SLC but not on a Micro1100. Hope it's not too confusing?

I was looking for a quick and easy way to copy or move that selection to another ST data file and the pick that tag on the panelview. Without Indirect Addressing I'm not sure there is a way? Thanks

Sorry. I am talking about String Data. Eg. ST10:0 is my first menu item. I'm trying to get ST10:0,St10:1,ST10:2.......ect....into ST10:49 then get that ST10:49 to display as the current selection on my panelview. Thanks
