Need some opinions on the following:
I have 4 VFDs controlling different motors. All communication, including on/off commands go through Ethernet. For safety purposes I want to disable drives by physically breaking connection between COM and ENABLE terminals when e-stop is pressed. Question is - can I use a single circuit and connect all coms and enables in parallel? For sure all coms can be interconnected but I am not sure if connecting digital inputs would not do any harm. VFDs are Emerson Commander SK series ranging from 1 to 3HP. All located inside the same enclosure. Thanks!
