Do air valves cause electrical noise?

I have a system that appears to be affected electrically by an air valve that is operating a clutch. This problem wasn't always there, but it is now. It seems to be causing electrical noise which in turn is affecting one of the servos on the machine.

Could electrical noise start after a valve gets older? Am I looking in the wrong place? Thanks!

Are Lenze AC Tech drives reliable?

Does anyone have feedback on these drives. Not looking for a specific model from them, just a general consensus on whether they are worthy as a replacement drive.

The prices are good and that always scares me...

Same thoughts here... a motor rated for 400V would indicate that it was designed for use in a 400V environment. I know if I were buying a replacement motor for a 400V motor that prematurely expired due to exposure to 480V, I would find a properly rated replacement motor.

I've actually never come across this situation, seems unusual unless you purchase a machine that was designed for use abroad. Here in the good old USA 480V 60Hz is the way we fly.

I look at it the other way, I was trained on a basic 20MHZ oscilloscope and to this day i would just prefer to dig out the old scope. Once you're familiar with the controls on a particular piece of test equipment, it's hard to get away from it.

Ladder logic is more visual for me. I just think it's easier since it resembles an electrical schematic. We have Siemens PLC's that use the function block style PLC programming and they can keep it. I can't someone thinking the block style is easier to troubleshoot a machine.
