Re: [CAD_CAM_EDM_DRO] Re: Power supply for Servos - Energy dump and such - UR...

There are actually two different dump circuits and the one that is being discussed is the over voltage type. That monitors the voltage and dumps anything over a set limit during operation, The DPDT dump circuit is another type that dumps the caps at shut down so the machine will stop abruptly rather than slowly proceed until caps are drained. It keeps the caps drained while anyone is working inside the enclosure, as long as the control is shut down.

the LM393 as opposed to using the simple DPDT relay dump circuit that
Mariss published before this?
