Hello, I am currently working with a Siemens S7-1200 PLC paired with a Schneider ATV320 drive, equipped with a Profinet communication module. Recently, the drive failed and was replaced with a new one, while the existing communication card was transferred to the new drive. I need guidance on restarting this system. Would adjusting the Fr1 parameter on the drive to 'nEt' be sufficient? Are there any other steps I should take? Thank you in advance for your assistance. - David
If you haven't configured Profinet on an ATV drive before, you will need to set a Profinet name and IP address, along with adjusting motor parameters. Don't forget to also configure the FR1 parameter for optimal performance.
In response to a query, chud mentioned that while they haven't used Profinet on an ATV previously, they believe that assigning a Profinet name and IP address, along with configuring motor parameters, is necessary. They also highlighted the importance of adjusting the fr1 parameter. The individual questioned whether the Profinet name and IP address are stored in the communication card. Nonetheless, they expressed gratitude for the information and indicated they would investigate further.
Hi David, resetting the Fr1 to 'nEt' would indeed be a great first step, as it will ensure that your Schneider drive is communicating over Profinet. However, remember that replacing the drive could mean different IDs or addresses. So, I would also recommend checking the configuration of your Profinet communication module on both your PLC and in the TIA Portal software. Verify that the IP addresses, subnet masks, and gateway addresses match the settings of the new drive. I'd also suggest re-importing the GSD file for the new drive into the TIA project, just in case there are any minor changes in the new version. Can't be too careful with these things. Good luck!
Hi David, yes, setting the Fr1 parameter on the drive to 'nEt' is a good starting point. Besides that, I'd suggest checking if the communication module is properly seated in the new drive. Also, make sure the IP address of the new drive matches that of the old one (if applicable). Additionally, I would recommend rechecking all the wiring and running a test cycle before putting the system back into production. Lastly, download and check the diagnostic buffer in TIA Portal for any additional hints if your setup still doesn't work. Best of luck!
