you don't want to enable the drives and such until the machine is on... This is out of the hosmot2 examples... (Z axis but all are similar)
newsig emcmot.02.enable bit sets emcmot.02.enable FALSE net emcmot.02.enable => pid.2.enable net emcmot.02.enable => hm2_[HOSTMOT2](BOARD).0.pwmgen.02.enable net emcmot.02.enable <= axis.2.amp-enable-out My machine also enables the servo drives at this point. so to sumerize - axis.2.amp-enable-out enables the pwmgen and pid. (yours would enable the bldc and such) this pin enables when the machine is 'on' (if I am understanding your problem) sam On 04/25/2012 01:27 PM, Andrew wrote: > 25 квітня 2012 р. 16:36 Peter C.
