Hello everyone! I am in need of assistance with configuring a Danfoss Aquadrive FC202 inverter. I am looking to set up the logic in a way that disables local commands when the PLC is connected to the inverter. The inverter will always be in "Auto ON" mode and operators will not be able to access the inverter HMI. In the "Auto ON" mode, local commands should take precedence, but only when the PLC is not communicating with the inverter. I am new to working with Danfoss products and have a limited timeframe of 2 days to figure out how to configure this setup. Any advice or tips would be greatly appreciated. Thank you!
What is the method of communication between the drive and PLC?
OkiePC inquired about the method of communication between the drive and the PLC, with Ethernet IP being the chosen protocol.
Hello! I've had some experience with Danfoss inverters before. I'm not sure about the specific model you're working with, but generally, you need to program the drive to operate in terminal control instead of local control. This will allow the drive to respond to commands from the PLC when connected. Make sure to configure the terminal control appropriately so it prioritizes signals from the PLC over local commands, but reverts back to local if the PLC connection is lost. Good luck with your project!
Hey there! It seems like you're trying to achieve a sort of interlock scenario with your Danfoss Aquadrive FC202 inverter. It doesn't exactly have an exclusive functionality like you described but you can achieve your objectives by using the Profibus/Profinet/Ethernet modules for communication with your PLC. In the parameter settings, look for 6-32 Control Source Setup. You can set it to Fieldbus to primarily allow PLC to take control, but it has a fallback to local controls when the fieldbus connection is lost. Refer to the manual for in-depth instructions on setting the parameters. Remember, proper logic programming on your PLC side is crucial to ensure smooth operation. Let me know if you need more help!

Answer: - To achieve this, you need to set up the logic in a way that ensures the inverter operates in "Auto ON" mode and restricts access to the inverter HMI when the PLC is connected. Local commands will take precedence only when the PLC is not communicating with the inverter.
Answer: - The inverter should be set to "Auto ON" mode to allow local commands to take precedence when the PLC is not communicating with the inverter.
Answer: - Given your limited timeframe, it is recommended to refer to the product manual or reach out to Danfoss technical support for assistance with configuring the Danfoss Aquadrive FC202 inverter as per your requirements.
