Pete, as far as i can see your hal file is fine , but the spindle values in your ini file should be along the lines of
[SPINDLE_9] ENCODER_SCALE = 4000.0 OUTPUT_SCALE = 10.0 #OUTPUT_MIN_LIMIT = -10.0 #OUTPUT_MAX_LIMIT = 10.0 could you let me know how you have the spindle drive connected and using what terminals on your 7i76 . as the output terminals on the 7i76 are isolated you need to make one side of the opto to volts or ground dependant on how your vfd is operated your spindle encoder is connected on encoder channel 0 which is ENCA + ( pin 7 )and IDX +(pin 13) and using the 5vp (pin6) and gnd (pin 9) as the power for the encoder , as your using single ended TTL input here and not differential encoders , then you will need to move w4,w5,w6 to the non default position (up ). you dont say what the number of counts your encoder has but this would be the value of Encoder_scale in the above , so change accordingly Dave On 17 September 2014 22:58, andy pugh <bodge...@gmail.com> wrote: > On 17 September 2014 22:53, <p...@wpnet.us> wrote: > > > On the instant reverse issue I am wondering if instead of using the > fully isolated enable and direction outputs provided by the 7i76 if I would > be better off setting up for fwd/rev control and using two of the general > field outputs (I have plenty free) which should still be fine since the VFD > is isolated itself and it's inputs are optos. > > That is pretty much what I have (using a 7i43) so ought to work.
