Stepper Driver Enable Best Practice: 7i76/7i76E

What is the best practice to provide a 5V Drive Enable signal to the Stepper Drives with a 7i76(e)?
I am planning to use 24VDC field power.

Should LinuxCNC control this signal, or is an E-Stop controlled 5V signal appropriate?

Does each axis need to be controlled independently, or is a single, shared signal acceptable?

Depending on the answers I will need to add relays to convert 24V outputs to 5V signal(s).

Thanks,

If you dont need all 5 stepgens you can use stepgen outputs for 5V signals

Note: many step motor drives have an enable must be powered to disable the drive
(that is they have a drive disable rather than an enable)

LinuxCNC's motion component has specific per axis drive enable pins, I would use these
(they are all switched at once so you can just use Axis 0's enable pin for a global enable)

The drive uses the "Motor Free" label for that input, so it may be what you are describing as a Disable, not an Enable.
