Danfoss drive commution

Hi guys ...just want to knw is it possible to bypass a 2 wire RS485 communication between plc and a Danfoss automated VFD.

You are going to need to provide more information about what you are trying to do and what you are trying to do it with.

We have a Danfoss VFD breakdown ....the caoacitors burnt.We have a spare Vfd but we cannot access the parameters beacuse the password had been changed and no one knws what is the password. So we are using the spare VFD with the old control keypad and its card but we are getting a communication error . We checked all the parameters for communication according to manual. We suspect that the communication RS485 is not giving signal to plc.Is there any way to fix this.

We had a problem with the vfd the caoacitors burnt. We have a spare vfd but we cannot access the parameters beacuse the password has been changed and no one knws the password. So we used the spare vfd and the old control keypad and its card but we are getting a communication error. The parameters are ok but we suspect that the communication is faulty. Is there any way to fix this
