How long does a vfd last

That is because the PowerFlex Medium Voltage drive has no power capacitors and does not use transistors. It has a bus inductor as the energy storage device instead of capacitors. The inductor is just copper wound around steel, nothing to fail there. Also as a Current Source Inverter CSI it is using power devices called SGCTs that are much much more robust than transistors and even if they fail, they fail shorted just like any thyristor so the drive can continue to run albeit rough until it is replaced.

Swop main processor board into spare hoping it will power up. I have done this before as long as its not the main board that failed. If so your hosed. I ask because it would be really handy to put a kill switch on the inbound supply. Is this a bad thing? Should I put the breaker between the VFD and th emotor?
