No PWM Output for Spindle in openloop test mode - 7i92 w 7i77/7i76

So I'm in PNCConf and I have my linear motors moving in open loop test mode, but when I go to open loop test mode on the Spindle tab, I get no DC Voltage output on the 7i77 Analog output 5.  HAL shows an output, but the multimeter shows nothing.  Attached are my 2 hal files and my ini.  Also is there a way to have a different max linear speed for my Z axis?  The head is heavy and the motor is tired, doesn't want to move it at 300ipm, but the x and y have no problem.

I would set the spindle speed to 1/2 full scale (3000)

(MDI)
M3S3000

and see if these make sense

hm2_7i92.0.7i77.0.1.analogout5
hm2_7i92.0.7i77.0.1.spinena

Then check the analog 5 output

Right now I can't get to MDI as the encoders are giving me fits, I can only move in "Open Loop" test mode in PNCConf. Once I get my encoders sorted, I'll try this, but right now I have zero response in PNCConf.

Also  I'm not sure if pncconf's open loop test can really access much other than
the axis analog outputs. A better test might be a very minimal hal file:

loadrt hostmot2
loadrt hm2_eth board_ip=10.10.10.10
loadrt threads
addf hm2_7i92.0.read thread1
addf hm2_7i92.0.write thread1
start
loadusr halshow

And then run this file with:

halcmd -f testfile.hal

or just

halcmd -kf

 and enter the lines by hand or copy-paste

At this point you should be able to set and view pins
with halshow

When done you will need to run:

halrun -U

To unload the drivers.




 

Thanks for all the help - I'm 1 failed encoder away from being able to use MDI to test the spindle. I may try that simple HAL file if I get time.

Finally got my encoders in, MDI S2000m3 and I get no response. Probing the analog 5 output, I see voltage (3.3v approx), which is what is expected. Probing my spindle enable output (7i76 Output 5), I see 0v. Checkng hal config, the LED is "on" for the 7i76 Output 5. If I apply 24v directly to this output pin I get spindle activity. I do not have a spindle encoder hooked up yet.

Do you mean 7I77 analog enable?

If so, this is a switch, not a voltage source
so you would need to wire:

+24V --> 7I77 ENA5+
7I77 ENA5- --> SPINDLE ENABLE IN

Found it, I thought I had commented out the invert line in my hal, I had not:

# --- SPINDLE-ENABLE ---
net spindle-enable => hm2_7i92.0.7i76.0.3.output-05
setp hm2_7i92.0.7i76.0.3.output-05-invert true
