Hi i have 5 VFD's connected through the 22 comm D adapter. They abruptly stop after 5/6 hours without any prior notification. Can you help me find the root cause please
You are going to have to help a bit more here.
Any error messages?
Any other problems on the DeviceNet loop?
How are the drives being controlled? DeviceNet only? or are there also safety circuits?
Any drive faults?
