We run our robots off the transformed voltage from our thermoformers. 120v or 240v I believe (can't remember which off the top of my head). That power is also supplying other things within the machines circuit. From my understanding of good practice my question is that shouldn't we have a 120v/120v (or 240v) transformer between the robot and machine to isolate the robot power and reduce potential noise? Is this worth doing or is it just overkill? I've brought this up before to management because we also supply our machines with straight 480v from the building transformer. My understanding is we should also have a 480/480 transformer at every machine. I'm no electrical expert, but I do have some intermediate understanding.
