Wiring Leadshine DM856 Ena+ and ENA- -> Mesa 7i76e was created by DerKlotz
Hi,
I would like to connect the ena+ and ena- inputs of my Leadshine DM856 to a Mesa 7i76e. If you look at the attachments... which circuit should I use? I would say PNP... but is that correct?

Yes, the PNP connection is correct for a 7I76E field output (With appropriate series resistor)
Note the the default operational mode for Step drive enable inputs is disabled when powered
(which is the exact opposite of the desired operation from a safety standpoint)
Unless you can reverse this (so they are enabled when the enable input is powered)
You may need to add an external relay.

Please see attached file
Can i just use one Mesa output for all three driver or do i have to use three outputs? One for each driver. In the LinuxCNC configuration i can set enable for x, y and z axis.

One output, but three resistors...
