5i25 + 7i85s +....

Dont know if its your issue but at the minimum you should set the PWM output type ( to 1 )
and PWM frequency ( to 5000 for the Spinx1 ) in your hal file

Hi,

I have set that two things in the HAL file, but continues doing the same. I didnt set the control-type in the HAL file because i checked with HAL configuration and it showed 1 , so i guessed that was the predeterminated value.

With the configuration i have the TX6 of the 7i85s should change its state by changing the direction of rotation, shouldnt it??

Thank you.

If i wire the DIR to non-TX6 it works, because this PIN is always LOW, so it works clock-wise all the time.

But now i have the problem with the TX7, the SPIN1X is always sending 10 V ( the reference of my VFD), no matter which value has pwmgen.00.value. Furthermore, if i push the stop button, TX7 continues HIGH ( the voltimeter reads 3,7 V ), no matter what i do in linuxcnc, TX7 is always HIGH, like TX6.

I think my problem is that TX6 and TX7 are not controlable by linuxcnc. My version of linuxcnc is 2.7.4, should i upgrade??

Thank you.

Are you sure you have a 7I85S, not a 7I85?
(check label on back of card)

This is very unlikely to be a LinuxCNC version dependent problem
(None of the PWM/driver code has changed for many years)

How is the 7I85S powered?

I think is a 7i85s. How can i diferenciate it??

Actually i control 3 motors with step+dir. I think this can be done just by 7i85s, cant it?

In the page of mesanet i cant see any differences in the photos.

Thank you.

I cant see the back of the card now because is mounted in a electric box, all wired. Im pretty sure that is a 7i85s, because i bought it with this post:

forum.linuxcnc.org/27-driver-boards/26525-mesa-doubt

When i did mesaflash --device 5i25 --readhmid before flashing it i saw sep/dir outputs. The 7i85 can handle step/dir outputs too?

I have stepgens working with it since i installed it.

Thank you.

EDIT: It is powered with the DB-25 paralel port cable from the 5i25.
