error from closed loop stepper

what hal pin will recive the error from a closed loop stepper

for rxample feeding a limit switch signal say to db25 bob say pin 10 

net all-limit       <= parport.0.pin-10-in
net all-limit => joint.0.neg-lim-sw-in
net all-limit => joint.0.pos-lim-sw-in

so linux take the signal from pin 10 and feed it to joint.0.neg-lim-sw-in (and other hal pins)


my question :

if the signal coming from pin 10 is actually coming from a closed loop stepper driver error,

what is the internal pin I should forward that signal to in this case ?

or do I just forward that signal to 
iocontrol.0.user-enable-out


Best regards

"joint.N.amp-fault-in"

Where "N" is the specific joint would be the appropriate pin to signal a drive fault.

If you only have a combined fault, just connect it to joint.0.amp-fault-in

unreal.  

many thanks
