My final point on this issue is that Siemens does make the PLC controllers but not the power inverters that power the centrifuge “motors”. The inverters only produce a limited amount of power, no matter how hard you step on the foot pedal, a car can only go so fast.
“The inverters only produce a limited amount of power, no matter how hard you step on the foot pedal, a car can only go so fast.”
Your statement is untrue!
Inverters convert 50 or 60 Hz power into DC power which is stored in a capacitor and chopped to reconstitute the power output to anything from 0 - 1000 Hz.
Inverters can EASILY be reprogrammed to to rapidly change the speed to 200% to 500% faster than normal in addition the safeties voltage, speed and current limiting reside in the inverter and can also be readily changed via software and changed back immediateley after “the event” just like nothing happened.

Siemens controllers talk to ABB and other drives what you call “power inverters” all day long all over the world.
maybe your is a different world.
