7i97+8i20 error function not found

Hi, I have a ongoing retrofitting project that I have just started working on again. So i have a old 3 axis takisawa mill with fanuc servos, and currently I am trying to get just the one servo working on the bench. It is 10s servo with fanucs own encoder, these are wired to 7i97 and 8i20 will control all 3-axis movement.

Been working couple of days after wiring with the PNCCONF, and for a beginner it seems alone to be a big task to get somehow right. I did some kind of configuration with the config tool using 7i92+7i77, and then just changed the board name in the ini file from 7i92 to 7i97, which gives me:Error report created by /usr/lib/tcltk/linuxcnc/show_errors.tcl:

So I am trying to get over that for the whole day and not really sure what that bldc.3 not found means, and how to work with that.. And I am also wondering about how the connection between 7i97+8i20 will work? (cut a cat5 cable in half and wired it like in instructions to the tb4 connector of the 7i97 for serial commutation, encoder is wired to encoder 0 and should be also right).
Attached the current HAL & INI files too. Thanks and sorry in advance!

okay, so now when i try to do ANY modification to the hal file, it will say:

Debug file information:
./takisawa.hal:1: Unknown command ''
27630
Stopping realtime threads
Unloading hal components
Note: Using POSIX realtime

and when after this i modify to it just the way it was (like if i just add a "," in somewhere and then taking it of and saving the hal file) it will give the same unknown command.. So I think that i am modifying it somewhat wrong way or in wrong place?

It sounds like you are editing the hal file with a word processor, not a plain text editor
I would suggest geany or mousepad or gedit for editing the hal file

I just ran pncconf for a 7I92/7I77 configuration, and here are the spindle related sections
in the INI and HAL file tha pncconf created:

Okay well that explained it, started using geany and made some progress, thank you really much on to the next problems:

So now I managed to modify the hal fie in the way that the linuxcnc actually opens. I have all wires and power connected to the 7i97 and to the 8i20. When i spin the servo by hand, the X-axis value changes just like it should and it looks accurate! I am using just the A+, A-, B+, B-, Z+, Z- signals from the encoder for this. The encoder has the COMM signals too but do i need them? or can I use just limit swithes and the ABZ-encoder for homing every time the machine is powered?

But if i try to jog the X-axis it wont move, so no power yet going to the poles (which is no surprise for me, I just don´t know what to do or try next). In the 8i20 status led is flashing, iso pwr GREEN, lv status YELLOW and pwr GREEN. I currentyly have 40VDC going to the motor power of 8i20, but can up that if needed later in testing (Makita batteries). the enable is just shared 5vdc from the 7i97 power input for now.

Current Hal and Ini files attached once again, pretty sure that there might be something unneeded in the Hal too (tried to search other similar setup Hal files but could not find any, hopefully I can one day make some kind of a guidenance for this kind of setup for first time linuxcnc beginners like I am.). And not anything spindle related yet, i`m just trying to get some movement to the servo for now on the bench, and hopefully get it to move just like it should eventually.

I dont seen any connections to 8I20 pins in the hal file
Did you select a 8I20 on the sserial port and set the BLDC
options in pnnconf

No I did not had it selected, that explains a lot :-).. Modified and selected it, but now there is lots of errors in the Hal file with the nets etc. I marked all the error spots with ##, where the debug file says "xxxxx" does not exist.. There is many of them, so i think there would be somehow common problem between them? And is it normal that in pnnconf in the BLDC section you can not alter most of the values? Maximum current or any of the values on the right bar. You can write a number but when you press enter they all return back to zero..

E: I Know that most of the values causing the error needs the correct operating value, but in which exact way it should be written to them for it to be correct? (this ain´t the correct way?: setp       [HMOT](CARD0).8i20.0.2..max_current 10.000 )

Is the 8I20 detected?

Have you listed the hal pins with:

halcmd show pin

?

setp       [HMOT](CARD0).8i20.0.2..max_current 10.000


I don't know where it has come from, but the double dots (2..max) isn't going to work.
