As a newbie to EMC you look at other files and they use linksp all thou the file but the manual never gives a explanation of linksp. If you search thru the manual it uses linksp several times in examples. So it kind of like stepping into a mud puddle the more you move around the muddier the puddle gets. The link above is for the new commands the fact there are new commands and still working old commands that are not explain added to the mud. If you look in section 5.4.3 of the hal manual it list command that can be use in hal but does not list net. I think adding a section to the link above that shows old but still useable commands would be helpful. Then add the whole thing to the hal manual would great.

Re: [Emc-users] absolute analog output signal 0 - 10 V
I'm not sure if they are deprecated or not... I don't think they are perhaps just obsolete. I was just as lost with linksp and other commands when I first started. In the trunk (2.3) there is only 4 linksp's left to fix. Now that you reminded me :). and yes I need to add the description for them in the basic hal section somewhere because you will find them in most older configurations and some if not most of the sample configurations.

Re: [Emc-users] absolute analog output signal 0 - 10 V
Tom wrote: Marko Bukovinsky bukovinsk...@... writes: how to change this code into abosolute 0 - 10 Volt output? ... Mark, Here is the abs statement from my m5i20_io.hal file, this might help you get the wording right: loadrt abs count=2 addf abs.0 servo-thread net spindle-rpm-cmd motion.spindle-speed-out newsig abs-spindle float linkps abs.0.in = spindle-rpm-cmd linkps abs.0.out = abs-spindle linksp abs-spindle = m5i20.0.dac-03-value setp m5i20.0.dac-03-offset 0 net SpindleOn motion.spindle-on linksp SpindleOn = m5i20.0.dac-03-enable setp m5i20.0.dac-03-gain [SPINDLE]DAC_SCALE I don't think it was necessary to load 2 abs realtime components, but that is what is in my file right now. If you are only using one abs component, then you should say count=1 (or leave count out - I'm about 99% sure the default is 1). If you do need more than one, remember to have an addf command for each one. The example above uses a mix of the old-style newsig/link notation and the current net notation, which I think makes it a bit confusing. Here is the same thing using only net notation: # route speed command through abs block to get 0-10V loadrt abs addf abs.0 servo-thread net spindle-rpm-cmd motion.spindle-speed-out = abs.0.in net spindle-rpm-cmd-abs abs.0.out = m5i20.0.dac-03-value # scale factor converts RPM into DAC volts setp m5i20.0.dac-03-gain [SPINDLE]DAC_SCALE setp m5i20.0.dac-03-offset 0 net spindle-on motion.spindle-on = m5i20.0.dac-03-enable I made a couple changes to signal names. Signal names can be whatever you want, so make life easy for yourself. The new names for the three signals all start with spindle, so when you do a halcmd show sig they will all be grouped together. The would also appear close together in a halscope or halmeter dialog box. The old ones started with spindle, Spindle, and abs, and would appear far apart in the listing or dialog. The most important change is that I added a couple comments - some people may have perfect memory, but I don't. When I want to change something on my machine a year or two after I did the initial config, comments will be vital to help me understand what I did back then. The second comment is a bit lame, but that's because I don't actually know anything about this setup. If it was my own machine, I would probably spell out the details, maybe something like: # 10V to the VFD gives 60Hz = 1780 motor RPM, belt ratio is 2:1 # so 10V = 890 RPM at the spindle. So 1V = 89 RPM. When speed # command is 89 RPM, I want 1V, so scale factor is 1/89 = 0.01123 setp m5i20.0.dac-03-gain 0.01123 Sure, if I can figure it out once, I can figure it out again later, but why? Write it down while you are doing it, then you'll never have to guess later. Regards, John Kasunich -- Check out the new SourceForge.net Marketplace.

I think I answered your question here.. (well one way..) http://www.cnczone.com/forums/showthread.php?t=71072 If I am understanding what you want.. Could you send the motion.spindle-speed-out thru abs? (take the absolute value of it) http://www.linuxcnc.org/docs/2.2/htm...an9/abs.9.html http://www.linuxcnc.org/docs/2.2/html/man/man9/abs.9.html then it would always be positive..
