Lenze 93xx Drive PLC

7 posts in this topic

Hi all, I now need to wrestle with a Lenze Servo Drive 93xx and the PLC within it. 

I have Global Drive Control & Global Drive PLC Developer Studio and have to swap a burned out drive for a new one, it's almost 20 years old and I wonder if anyone can advise, can I pull the PLC project / code out of the drive PLC on the old unit (it still communicates but the I/O is blown for analogue inputs) or is that not possible?

Someone told me that on the Lenze Servo PLC drives, you cannot get the code back into the DDS software once compiled and loaded. I've asked the originator of the machine if they still have the full project (unlikely as it was 2005 vintage)

I can get all of the parameters via GDC but the PLC part only communicates over CANBUS and not the LECOM-AB so I have the correct cable coming and have the software already, awaiting the project from the OEM but if anyone knows how to upload (even just to pull out and squirt back in compiled state) then I'd be grateful.

I also know there was a device numbered EMZ2221IB which could do a pull & push of the PLC code just to clone a drive PLC but the gadget is like rocking horse poop.

AB/Rockwell is my normal thing among all the other makes we have to work on in Controls but Lenze Drive PLCs are a new beast for me.

 I also heard its possible to get the PLC program using CoDeSys but not sure on that one, as I can't find any information on how to do it. I have the Lecom-AB interface, USB to CAN interface and the X4 CANBUS cable so if I had software capable of pulling the program out, even in compiled form, I could get the machine working again. Any help or pointers would be most appreciated.

I have limited experience with Lenze drives, but I do remember having a multi-page work instruction (with screenshots) explaining how to upload/download/activate/store the parameters using GDC. It was very possible and very easy with the right procedure but the procedure was not obvious or intuitive. I had to do something similar with newer drives using Easy Starter. That was similarly involved. I'm not at that location any more and I can't find the instructions I had or I would share them here.

Hi Joe, thanks for replying. I now know, having gotten a call-back from Lenze UK TS, that the 9300 series PLC drives can NOT have their PLC code uploaded, and to replace one of these drives which does use the PLC section, you have only two options:

1. Get the EMZ2221IB interface, pretty much rare as unicorn poop and expensive if you can find one (<£2K GBP) - only works with versions 6A5x onwards - this interface can suck out the compiled code and squirt it back into a replacement drive. No editing possible (compiled binary file)

2. Get the original PLC project from the machinery vendor if possible and use DDS (Global Drive Developer Studio) to edit and/or recompile and download to the drive.

It is not possible to use GDC to get the PLC code, but also learned that only 93xx-EI or 93xx-ET have the full PLC inside, 93xx-ES drives do not. For those not using the PLC then GDC Easy can get all parameters including function block values but can NOT edit the FB, for that you need the licensed version of GDC as it has the FB editor built in.

Can you get the code from the machine builder? We were fortunate in that we did have access to them and they were helpful. We also ended up buying a license for the "Easy Professional" software so we could make changes to the code in the drive. That was definitely an exercise in frustration trying to figure out, but it wasn't too bad once we did. I wish I had access to the instructions so I could share them, but they may not be super helpful with a different model drive.

FYI, most of the drives we had were EVS9325-EKV004 and GDC was all we needed.The drives we used Easy Pro for were L-Force 9400 HighLine.

I have actually asked and in one case the vendor is no longer around but on the other machine the guys moved to a new company when their old employer shut down so they have agreed to send me the project as they still have it, so that will work fine, many thanks for the response Joe.

It's really annoying when a company goes out of business like that. I had an issue with a machine where the company was bought and that division went away with no records left. We were completely out of luck.
