In order to protect a VFD from overheating a common solution is to incorporate a braking resistor to dissipate the heat. This video goes through the different ways to protect a braking resistor from overheating.

the braking resistor in one of our centrifuge machine caught fire when one guy decided to bypass the contactor for the vfd

I'm sure that was a headache for everyone involved. Properly installed overheating protection is important for pretty much any machine. I hope this was a learning experience for the person who bypassed the contactor.

The main method I'd deploy to achieve this is to increase the deceleration period to a workable period that does not compromise the application or safety. And the other trick is to avoid un-necessary dynamic braking.

Hi Elevator and crane application we can't switch off resistance ro VFD Inverter any other idea? normally we use higher watt resistance resistance become very hot sum time

What if the VFD could have over voltage, is it possible to get overheating/burning of your braking resistor ?....

But the real question is: do you write on the glass in the regular way and then mirror it or you already write it mirrored?

We've been asked this question before. Mike writes normally and then we mirror the video so the text show the correct way. Thanks for the question.
