Spindle brake delay vs E-Stop was created by Tom_R2E3
Hopefully this hasn't been asked before...
My Mill has a spindle brake. I would like to have a delay to the activation of the brake when I stop the spindle, UNLESS I have activated E-stop. Is there a simple way to set this up in the HAL file?
This is my spindle brake section at the moment:
So at the moment I have a second delay for the spindle brake in all conditions.
Thanks in advance,
Tom

This is my spindle brake section at the moment:
# -------------------------- SPINDLE BRAKE ------------------------------------
# Intended operation: motion.spindle-brake controls the brake UNLESS the button connected to input-10 is held down
loadrt timedelay count=1
addf timedelay.0 servo-thread
net spindle-brake xor2.0.in0 <= motion.spindle-brake
net spindle-brake-button xor2.0.in1 <= hm2_5i25.0.7i77.0.0.input-10
setp hm2_5i25.0.7i77.0.0.output-00-invert 1
net spindle-brake-both xor2.0.out => timedelay.0.in
net spindle-delayed timedelay.0.out => hm2_5i25.0.7i77.0.0.output-00
setp timedelay.0.on-delay 5
setp timedelay.0.off-delay 0So at the moment I have a second delay for the spindle brake in all conditions.
Thanks in advance,
Tom

Using inverted spindle-on pin might have been easier and better, in my opinion.
Adding a timedelay when stopping the spindle and adding AND to e-stop out, so the brake will be delayed when stopping it normally and would engage immediately on E-stop.
Something like:

Something like:
spin-on>invert>timedelay>
------------------------------------|and >brake

I have do something similar with enable signal that work fine i think you can check and adapt for brake.

cand you use a simple ramp UP and Ramp down
