7i73 Analog in problem? was created by greekart
Hello guys,
i have pots for feed/rapid/jog override, the ones for feed/rapid works but for jog not.
I have 7i96s with 7i73 connected, with pots connected to analog 0,1,2 inputs of 7i73
[/code]

loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=1 num_pwmgens=1 num_stepgens=5 sserial_port_0=10xxxxxx"
in my hal for jog override i use
[code]loadrt hyst names=hyst.feedpot,hyst.rapidpot,hyst.jogpot
loadrt scale names=scale.jog
net jogpot-raw hm2_7i96s.0.7i73.0.0.analogin1
addf scale.jog servo-thread
addf hyst.jogpot servo-thread
setp hyst.jogpot.gain 0.05
setp hyst.jogpot.deadband 0.7
setp hyst.jogpot.step 0.01
setp hm2_7i96s.0.7i73.0.0.analogin1-scalemax 1.58
net jogpot-raw hyst.jogpot.in
setp scale.jog.in 5000
setp scale.jog.offset 50
net jog-speed-gain hyst.jogpot.out scale.jog.gain
net jog-speed scale.jog.out
My problem is that in hal_show when i change jog pot in analog 1 the analog 3 changes too and don't know if the code or the inputs are the problem, any thoughts?
Thanks a lot Panos.

There is an issue with analog inputs 1 and 3 on the 7I73
there seems to be electrical leakage (about 50K ohms)
between inputs 1 and 3. Suggest using analog inputs
1 or 3 but not both until this is figured out. It may be fixable
in the 7I73 firmware but I am not sure currently.

Ok, i will leave one unused. So i guess that not affect gui/machine and i will look from hal point why the jog-speed not work.There is an issue with analog inputs 1 and 3 on the 7I73
