(OPTO off) on a watchdog bite or at power up. I have a relay that powers the drives that are run from an estop/mesa ssr... So this would not be a problem as if the watchdog bits or whatever - that relay drops out sam A spare SSR output may do (no issue inverting it) On Wed, Jan 29, 2025 at 5:54??PM Sam Sokolik <samco...@gmail.com> wrote:
ok - Maybe I can invert it at the drive.. AMC seems to be willy nilly on how it is setup (the 2 drives I have are totally opposite enable.)

Anyway - I did some testing. If you set 'setp hm2_7i97.0.pwmgen.04.enable.invert_output true' the output instantly goes to -10v When you enable the pwmgen - then it goes to 10v.. It works normally if you don't invert the enable. It does invert the enable though (this drive needed an inverted enable to work) sam Yeah, you cannot do that (invert the enable) on a 7I97/7I97T/7I36 as the PWM enable also effects the analog circuitry. It also would enable your drive (OPTO off) on a watchdog bite or at power up. Probably need to use an external relay or form B opto On Wed, Jan 29, 2025 at 5:11????PM Sam Sokolik <samco...@gmail.com> wrote: > > > On Wed, Jan 29, 2025 at 9:56????AM Sam Sokolik <samco...@gmail.com> wrote: > >> I thought that inverted the enable output?
