Dear all,

       We are facing a "Application/Technological function faulty" maintenance error in the PLC due to the G120 drives. The VFD itself is not generating any fault but only the PLC. This is occuring for all the VFDs used in the project and require some expertise advise to sort out the issue. The screen shot is attached for your reference.

       Thanks in advance.
