Re: [CAD_CAM_EDM_DRO] Chopper max voltage?

20Khz or there abouts is commonly quoted on Application notes, I've used the
App note values (3.3nf and 22k) for the R/C as well as 3.3nf and 10k which
gave about 42khz I seem to remember... The higher frequency gives higher
switching loses in the 298 (gets hotter) but works fine. I can't remember
the reason for the higher frequency now..

Cheers, Chris.
