Normally the brake will be controlled via the servo drive, you could however control it from the enable outputs.

Yes i am doing it using output but i am using RUN signal

Is that any signal specific for axis only? So that i can control axis brakes independently

I do not know what drives you have but as said earlier it is normal for servo drives to have a means of enabling/disabling a brake.
If your servo drives do not have that option then the best option would be to have the brake connected to one of  the enable outputs in Mach. That would mean when when you take Mach out of reset the drive would get enabled and also the brake would be released.

If you require the brake to be only released at specific times then you would have to do something different but without knowing exactly what you are trying to achieve it is impossible to say what would be best.

No I mean E000, you do not enter th 0x

If you are meaning Jog the spindle from MPG  then the only way would be to use SwapAxis() and treat it as an axis.

I wrote e000 but its automatically taking 0xE000 and my second board doesnt work at all

Afraid not, if there is no OEM for that then it would seem there is no built in function in Mach.
