PnCConf Setup issue with the Spindle
13 Apr 2016 21:35 #73258
by twender
PnCConf Setup issue with the Spindle was created by twender
I recently upgraded to Mesa (6i25 & 7i76) boards from Parallel control on my lathe. Having some trouble understanding my error when starting linuxcnc. Trying to use Analog out to control my spindle (0-10 VDC).
My error is: ./lathe.hal:178: parameter or pin 'hm2_5i25.0.7i76.0.0.spinout-minlim' not found
Error loghal file:
ini file
A solution is good, but understanding is what I am after.
Any guiding help is greatly appreciated!

A couple of possibilities:
1. No field power to the 7I76 (or no 5V)
both yellow LEDS on the top edge of the 7I76 should be illuminated
2. 6I25 has wrong firmware (if it was ordered as a set with the 7I76 it should be correct )
verify/reprogram with mesaflash

It was my ignorance. No power connected to TB1 (Field Power). I didn't realize you had to have voltage applied to start linuxcnc.
So, Thanks again!
I am still having issue with my spindle in that it won't show signs of life, but I need to take a closer look to ensure I have not done something wrong again...
...Likely.
On TB4 of the 7i76, I have:
PIN1: 0VDC
PIN2: OUT TO MY SPEED CONTROLLER (Previously working with PWM to a cheap 0-10 VDC board with no feedback)
PIN3: +15VDC
PIN4: NC
PIN5: SPINDLE ENA-
PIN6: SPINDLE ENA+
PIN7: SPINDLE DIR-
PIN8: SPINDLE DIR+
I plan on using the ENA and DIR outputs to control ON/OFF and DIRECTION of my spindle. Is this correct? I think I could also, pick another GPIO on the 7i76 to accomplish the same task. Correct? I am trying to understand behind the curtain, and I hope not to ask too many ignorant questions. But, at this point I am that.
Before Mesa I previously used PWM and a cheap board with no feedback. I have the encoder working within pncconf, but no spindle movement. My axes configuration appears to work fine.
Does a cursory look at my .hal and .ini reveal any obvious issues with regards to spindle control? There may be none, but I have been unable to run the spindle (After power to the field I/O and TB4) and I thought an expert could say "Looks good" or "This may be your problem".
Thanks

Some versions of PnCConf have a hal file error with the spindle signal names.
I would look carefully at how the spindle signal is connected in hal
The ENA and DIR signals have an advantage over other 7I76 outputs in that they are uncommitted switches
so can either pull-up or pull down to any required voltage. The 7I76 output can only pull-up to the common field voltage

Running 2.7.4
Finally got the spindle spinning in Pncconf Spindle Open Loop test. But, I still can't run in linuxcnc.
I currently have the spindle configured to Turn ON, CW rotation, and CCW rotation via Outputs on TB5.These worked in PnCConf, but not in linuxcnc. I did not use the connections on the spindle connector because I was not sure how to use them. Any help on understanding the 2 signals from a hookup pov is appreciated (SPINDLE ENA-, SPINDLE ENA+, SPINDLE DIR-, SPINDLE DIR+).
I am hoping my issue at this point relates to the fact that I did not use the spindle connector for Spindle ENA and Spindle DIR.
Here are my latest hal file and ini file:

Replied by PCW on topic PnCConf Setup issue with the Spindle
The error in PnCConf (this has been fixed in later versions) is this:
net spindle-vel-cmd-abs => hm2_5i25.0.7i76.0.0.spinout
net spindle-vel-cmd-rpm-abs <= motion.spindle-speed-out-abs
Note the the actual physical HAL pin is unconnected do to a net name error (the missing rpm in the top line)
The ENA and DIR outputs are simple switches.
so for example if your VFD needs a +24V signal to enable, you would wire the ENA signal like this:
+24V --> ENA+ -->ENA- -->VFD Enable input
if your VFD needed a signal to be grounded to enable you would wire the ENA pins like this:
VFD Enable input --> ENA+ --> ENA- --> GND
net spindle-vel-cmd-abs => hm2_5i25.0.7i76.0.0.spinout
net spindle-vel-cmd-rpm-abs <= motion.spindle-speed-out-abs

Your explanation of the switch makes sense now. You indicated a simple switch earlier, but it now makes sense to me. I guess switch means switch. Thank you for your patience.
I am still a bit confused about the spindle error...Not surprising given my history of questions.
I have read the explanation of net in the Basic HAL tutorial, but I don't think I understand well enough to explain what is going on with the net command. Does the net command do the following with the line in question: spindle-vel-cmd-rpm-abs (linuxcnc code signal) is "sent to" the Mesa card analog out.
Are you indicating PnCConf has a error in creating a connection to the intended signal name "spindle-vel-cmd-rpm-abs" since PnCConf creates "spindle-vel-cmd-abs"?

- If this is the case, I assume I should edit my hal file with the correction...net spindle-vel-cmd-rpm-abs => hm2_5i25.0.7i76.0.0.spinout?
- If the above is the case, can I add this command to my custom.hal file? Will it assign it correctly since it is the last connection made to the 7i76...spinout?

Yes (your version of) PnCConf has mis-matched net names so the desired connection
from motion.spindle-speed-out-abs to hm2_5i25.0.7i76.0.0.spinout is not made
(Note that net names are completely arbitrary, they are really just a wire or signal names )
so
net blue_wire => hm2_5i25.0.7i76.0.0.spinout
net blue_wire <= motion.spindle-speed-out-abs
will work
but
net blue_wire => hm2_5i25.0.7i76.0.0.spinout
net red_wire <= motion.spindle-speed-out-abs
is legal but does not connect the desired pins

Replied by twender on topic PnCConf Setup issue with the Spindle
I changed the .hal file to reflect "net spindle-vel-cmd-rpm-abs => hm2_5i25.0.7i76.0.0.spinout"
I now have the spindle turning in linuxcnc with manual and MDI controls. I also changed my wiring to utilize the switches on the the spindle connector. Works perfectly! Thanks
I also have an encoder (1000ppr, A,B, with index). It shows positional changes and speed inside of PnCConf (Though it is wrong at this point... I will setup the scale later). But, when I use linuxcnc I show no speed when the spindle runs. I assume there is another wrong signal connection. Is this the case when looking at my above hal file?
Thank you.
