There is no perceptible rotor cogging when you spin them by hand. 

Nice to know, thank you for taking the time to explain that.

Good, thanks for verifying the servos are programmed appropriately.

Right now, your HLFB pins are HIGH (conducting) when the servos are enabled and OK.  Since you have the inputs connected to your amp-fault-in pins like:

LCNC thinks there is a fault when the servos are saying everything is OK.  Here's the LCNC manual section (motion):

joint.N.amp-fault-in IN BIT should be driven TRUE if an external fault is detected with the amplifier for this joint.

Try changing the HLFB input pins to 'not' like so:
At that point, the joint.N.amp-fault-in pins should be HIGH when the servos are not enabled, and go LOW when they are enabled and OK.

Once you're at that point, you can test by pulling the encoder cable off the motors and see if it causes the amp-fault-in to go high (hopefully).

If you still need a delay we can work on that next.

OK I corrected the .hal file and pins are reversed like you said but unfortunately still same issue no pop up in GUI no indication something wrong. I can move the axis linuxcnc thinks everything is OK.

I think the problem is that the joints are supposed to have numbers, not letters.

Like 

joint.0.amp-fault-in

I just realized you haven't created a signal name, just linked two pins.  Because your joint.(lettter).amp-fault-in pin doesn't actually exist, LCNC is creating a SIGNAL named joint.(letter).amp-fault-in.

That's why you aren't getting an error at startup.

Try this

net x-fault joint.0.amp-fault-in hm2_7i96s.0.inm.00.input-1-not

and so on for the others.
 

I tried changing the naming, but had to use different name because was already assigned to pin.I get joint fault as soon as i try to enable I did try changing delay thinking that was it but no luck.  Unless I still having a naming issue with the pins unfortunately I still don't understand this part yet.
