Would have been much better as 4 axis would be standard pins.

New ethercat / probe basic control for minimonster

Category: CNC Machines

So i can change those pins in halshow, but they do nothing. So I expect they are not the correct pins for start/stop freq etc. Sound right?

Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
Do I just go one by one and set them to 1/0 and see if the drive turns on? I guess that makes plausible sense. there only 54 of them

Stepper motors should hold position when error.

Category: General LinuxCNC Questions

If the drive itself drops the holding current on a fault,
you are always going to lose position, there is really
nothing LinuxCNC can do about this.

How far it drops depends on how fast the drive can be
reset or brake applied. LinuxCNC can react very quickly
to  a fault signal (< 1 ms), but I would expect the external hardware
(brake or drive reset) to be slower.

You would need to specify which pins are:

yes. pin does not exist on yours too. (i changed the names of course to match). it post this before the parsing of the ini... which seems wrong. it should parse first right? I think it was before.

not typing from the same machine so i cant copy paste, but im using your hal snippet but with my names (mb2hal.00.start_stop) etc.
# Load mb2hal for modbus operation of the sinusM vfd
loadusr -Wn sinusM mb2hal config=sinusM_spindle.ini

...

# Set max limit rpm for spindle
#
net spindle-max-freq       sinusM.05.read-max-freq.float spindlemax.max         # Max frequency(rps) for motor
net  spindle-speed-scale   spindle.0.speed-out-rps-abs   sinusM.01.set-freq     # Just the principle

net spindle-vel-positive    mux4.0.sel0           abs.spindle-speed.sign
net spindle-enable          mux4.0.sel1
net spindle-cmd-out         mux4.0.out            sinusM.04.run-command  # Stop/fwd/rev

ah yes. ill try you thing again. chat gpt has begun feeding me a loop of trash now. haha.

The main thing l get is "pin does not exist". ill try yours now and see if i get the same.

I don't know what a logical way is to you, but it sounds like normal Modbus.
Didn't see a problem with byte order yet? Maybe that will come, maybe maybe not :)

If you now go back to my example snippets, you may see how the function code and register address
are mapped into a hal pin.
Didn't include the port setup guess it is different everywhere
I would start writing with write to a harmless register, perhaps something that switches on a led, I don't know what is available.

If I give you the inputs and outputs, could someone who knows something about this make this xx.bit file for me?


Actually that is why I asked:

"Can you post the pinout of your expansion card? "

As the first reply to this thread...

So function 3 and 4 in modpoll are reversed from mb2hal. Because of course it is. So I need function 3 vs 4 in modpoll. And I need to specify the hex number (2100 for example), and not the decimal 8448. NOW it is reading.

I know I have registers from 2048 to 2102 but I don't know what they do. apparently what little instructions I had about the drive are incorrect.

Have not tried writing yet cause I don't want to write something incorrect

Thoughts on how to map the registers in a logical way?

so modpoll can talk to the drive... mb2hal cannot. all settings seem to be correct.
what could be missing/wrong?

I've played with various timeouts and other things, i get the same transaction failure whether the drive is turned on or off, so its not even sending the message.
