Hello,

This is my first post on this forum.
I have a MESA 7i76E card for controlling my EMCO TURN120 lathe machine.
After running the PNCconf i got a strange error!
LinuxCNC is not able to bootup i got this error: "Parameter or pin 'hm2_7i76e.0.7i76.0.0.spinout-minlim' not found"?

After day's of google and try and error, i can't find a solution.

Any ideas how to solve this problem?

Thanks!

This usually means that you have no field power on the isolated I/O section

Thanks for your answer.
After connecting the field power (12V). The dir and EN works!
But, the analog out not yet.. Whem i run M3 S100 or M3 S1000 the anloge output stay 0V

Connection overview:
TB4-1 = GND VFD
TB4-2 = Analog in VFD
TB4-3 = 10V VFD
TB4-4 = NC
TB4-5 = EN input VFD
TB4-6 = 15V VFD
TB4-7 = REV input VFD
TB4-8 = 15V VFD

Any ideas how to solve this problem?

Thanks!

Can you post your hal and ini files?

Its likely something is not connected/scaled correctly in the ha/inil files

Thanks for your answer.

See attachment for my Hal and ini file.

My hardware setup:
I have a single ended encoder on my spindel, this encoder generatie 150 PPR with a index signal.
I connect the encoder signal on connector TB3-7 and my index signal on TB3-13.

Is that correct with my Hall files?

Thanks

The hal file looks basically OK
You might check that you have 10V measured from TB4.4 to TB4.1
and that spindle-vel-cmd-rpm-abs is the expected value (and spindle-enable is true)

Thanks for your reply.
My analog output works!
Thanks!

But my feedback doesn't work, my hardware connections are correct?

Thanks

Hard to tell. The HAL looks OK, but you have only listed the VFD hardware connections, not the spindle-encoder connections.

Sorry, my mistake.

My hardware connections for my spindel-encoder:
TB3-6: +5V for encoder
TB3-7: TTL Pulse encoder (150 ppr)
TB3-9: GND for encoder
TB3-13: TTL Index Pulse

Thanks!

Since you do not have a quadrature encoder you must set the encoder counter
to up/down mode, changing

setp hm2_7i76e.0.encoder.00.counter-mode 0

to

setp hm2_7i76e.0.encoder.00.counter-mode 1

(you may also need to invert the scale, that is from 150 to -150 to get the count direction correct)
