I purchased a 7i97 as I would like to cnc it at some point - but currently I just need 2 analog outputs, encoder outputs and some i/o. anyway. I have been goofing around with it and it seems that pwmgen.04 isn't working correctly. I am using this simple hal file for testing loadrt hostmot2 loadrt hm2_eth board_ip=10.10.10.10 loadrt threads name1=slow period1=1000000 addf hm2_7i97.0.read slow addf hm2_7i97.0.write slow setp hm2_7i97.0.pwmgen.pdm_frequency 75000 setp hm2_7i97.0.pwmgen.00.offset-mode TRUE setp hm2_7i97.0.pwmgen.00.output-type 1 setp hm2_7i97.0.pwmgen.04.output-type 1 setp hm2_7i97.0.pwmgen.04.offset-mode TRUE setp hm2_7i97.0.pwmgen.04.enable.invert_output true #setp hm2_7i97.0.pwmgen.00.enable true #setp hm2_7i97.0.pwmgen.00.value .5 setp hm2_7i97.0.encoder.00.scale 4096 start
I suspect its: setp hm2_7i97.0.pwmgen.04.enable.invert_output true
pwmgen.00 works correctly. when I enable it - the output voltage is 0. If I set the output to 1 - it is 10v and when I set it to -1 it is -10v.. perfect When I enable pwmgen.04 - I instantly get 10v on the output. If I set the output to -1 - I get 0v out. pwmgen.05 works correctly too... what am I doing wrong? sam _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
