Stepper motors should hold position when error.

I am running a 3 axis CNC mill with stepper motors, through a 7i76eu card running linux CNC. Currently when one of the motor drivers gets a fault, the motor lose all power. This is problematic for the Z axis, which uses a stepper motor with a brake. When its driver gets a fault the brake is engaged, but there is a delay, in the meantime the z axis is in free fall for about 10cm. Is it possible to program the stepper drivers in such a way that when they get a fault they stop the motors and hold the position.

Thank you for all the answer and suggestions in advance.

How does LinuxCNC/Mesa know there was a fault?
If drives have fault out, there might be something we can do, but for now i am out of commission as i spent the whole day chasing python scripts to output gcode for 3 and 4 axis machines from some really obtuse files some proprietary software outputs.

Faults from stepper drivers are wired as inputs on mesa card. When fault is triggered mesa triggers emergency stop.

Does the drive itself power down on a fault?

Yes,

the motor driver detects the fault and sends the signal to the the mesa. When driver detects the fault it also disables the motor (causing the z axis to fall). What I want is for the driver to stop the motor and hold position when it detects a fault not disable it.

Can you change the drives disable behaviour?
If not, is there a way to reset the drive?
