7i97T and analogous + Siemens 611

Category: General LinuxCNC Questions

Hey everyone

I have managed to completely interface with a Siemens 611, enabling it, clearing faults, reading encoder etc.
they move well when I apply voltage to the analog port.
its a huge tandem machine with two Y axis but I’ll be copying the signal as there’s no need for gantry skew correction.
I’m using a 7i97T but the analog part is not working as intended: no voltage comes out at all!

im using a 7i97T test config from the forums because there’s no PNCconf for 7i97T.
but, although the config runs, I have no analog output in any of the ports.

I assume it is configuration, because the config provided is using pwmgens and MAX_OUTPUT but no analog out or Min/Max.

does anyone have a working config for the 7i97t or 7i97?

thank you
best regards

My apologies for spamming this forum with stupid questions,
but I was short on time, hehe.

Finally, success. I outsmarted the probe with the Great HAL:
setp                flipflop.0.set              FALSE
setp                flipflop.0.data             TRUE
net probepin        parport.0.pin-11-in-not  => flipflop.0.clk
net probereset      motion.digital-out-00    => flipflop.0.reset
net probefiltered   flipflop.0.out           => motion.probe-input  parport.0.pin-01-out

Then use M64/M64 P0 to keep the flipflop in reset during the retraction:
  ...

  G38.2 Z#8

  M64 P0    (reset probe flipflop HIGH)
  G0 Z#7
  M65 P0    (reset probe flipflop LOW)

  ...


Out probing,

Servo Spindle with velocity AND position mode for Toolchanger?

Category: Advanced Configuration

hi
i think here is it better instead of my retrofit thread.

the emco vmc100 has a carousel which is turned by the spindle.

i use the original spindle hardware.
i can tap threads and mill. there is a encoder on top of the spindledrive.

with m19 r p i can orient the spindle.

now i came to the point that orient not works for the toolchanger because 2 spindle rotation are 1 positionchange from slot to slot.

could someone help me to get it work in position and velocity mode?

to enable the spindle i have a relay. if the relay open the drive is disabled and i can turn the spindle by hand.

if its enable the spindle is blocked and the pid bring it back to position.

thanks i will upload my hal in a hour
