Not currently possible - but you could use classicladder to enable the amps.

so axis.0.amp−enable−out goes into classicladder and you use classicladder outputs to enable your amps.

Why do you wish to disable one amp but not the others?

>>i actually use classiclader to enable servo amps.

if i disable "axis.0.amp−enable−out" i found that position command to servo drive become zero and this is very use full when we use c axis and spindle on same motor

when i switch from spindle to c axis i apply emergency(io control) for 100 ms and
and remove so i found that axis position command become zero

and same time i reset my motor feedback value zero inside servo drive

so migration c axis to spindle become easy

i need this for c axis only thats why i ask for only one axis out put disable

hope you understand my requirement

Yes that makes perfect sense.
I would still have axis.0.amp−enable−out go into classicladder to kill your C axis if the machine is turned off/estopped.

I have a four axis config but use a very seldom. In fact it is even plugable and so i have the driver normaly disabled via enable pin. XYZ enabled when in machine on, A only via toggle. All solved in ladder.
