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.

Hi I am having a problem with an error/fault code. The fault comes from a lenze drive as an integer. We have a proface HMI monitoring a DBW in the siemens S7 300 that holds the lenze fault code. The PLC comes up with a generic code "lenze drive fault". The proface comes up with the drive code. I would like the PLC to produce a fault description using the lenze fault code in the DBW, instead of the generic one [listed above]. could anyone please help with this problem Thanks Robbo
