JeffB Posted March 21, 2020 Share Posted March 21, 2020 For both the turbo and power PMAC we are using the 4 axis board ACC-24E2A. For the Turbo PMAC we used the M415->X:$78218,19,1;232 as a digital input. From the Power PMAC Software Reference Manual p1556 it looks like this should be Gate1[4].Chan[3].UserFlag. The gate and channel selection seems ok because I can control the Gate1[4].Chan[3].Dac[1] output from the PMAC. Normally I read a 1 for Gate1[4].Chan[3].UserFlag (as expected). When I apply 24 volts to USER4 as in the yellow wire in the photo, I expect to read a 0, but the watch window still shows a 1. It works for the turbo PMAC but not the power PMAC. Is there some mode or configuration I have to change for this to work? If it matters, the Gate1[4].Chan[3].UserFlag's address is $c76000e0 (M8243) Thanks Link to comment Share on other sites More sharing options...
DaveBarnett Posted March 21, 2020 Share Posted March 21, 2020 'Pretty sure that the flag inputs for the four axes are optically isolated..from each other. So, the "FL RT4" terminal needs a wire for the return current path...no? Link to comment Share on other sites More sharing options...
JeffB Posted March 23, 2020 Author Share Posted March 23, 2020 You're correct, thanks! The purple wire was on the wrong connector... Link to comment Share on other sites More sharing options...
