Hi,

I connected Mesa 7i76 to VFD as andypugh answered in this topic forum.linuxcnc.org/27-driver-boards/3537...wiring-to-mesa-7i76e and used PnCConf Wizard to save following configuration:

File Attachment:

File Name: sp-864.ini
File Size:4 KB

File Attachment:

File Name: sp-864.hal
File Size:10 KB


Unfortunately I cannot run Linuxcnc due to error:
./sp-864.hal:197: parameter or pin 'hm2_5i25.0.7i76.0.0.spinout-minlim' not found

Can you please tell me how to fix it?

P.S. I use newest version from master branch

You will likely get that error if the 7I76 is not discovered. This is most likely because:

1. The 7I76 has no field power /VIN power
(make sure 7I76 W1 is in the left hand position and that 8 to 32VDC are supplied to TB1)

2. The 7I76 has no 5V power (normally is easiest to use FPGA card power for this so
7I76 W2 in left hand position, FPGA card set to supply 5V power on cable)

3. Wrong firmware on FPGA card (verify with mesaflash --readhmid option)

4. Setup/operate jumper (W3) on 7I76 set to setup mode
make sure W3 is in the "left" or operate position

Before setting up spindle Linuxcnc run without problems and all axis were moving correctly, so probably 7i76 is discovered and has power(?)

Maybe this report will be helpful:

The log shows that the field I/O / spindle section of the 7I76 was not discovered

step/dir outputs and the encoder will work without this

I don't know what it means. Can you please explain?

8 to 32VDC are supplied to TB1

TB1 (Orange 8 pin terminal block) is the 7I76's field power connection
it needs 8 to 32VDC applied (Plus on pin1 = bottom pin, Minus/Common on top = pin 8)

Thank you. I plugged +10VDC and VFIELD LED lights up. mesaflash output did not change, LinuxCNC starts without any error but spindle still does not work.

The mesaflash output will not change, the startup log will however and the
missing pins will be available in the hal file

The spindle not working is most likely a wiring or hal/ini file setup issue

you shoudt check """#""" uncomment all errors
and look first if the pins are available

is the 5i25 7i76 a plug and play component or did you flash it with the firmware

Problem is solved! Beside lack of power in TB1 I had incorrect settings in VFD.
Thank you for your help!
