Hello!

I have Leadshine HBS86 hybrid servo drives and EdingCNC USB-CPU. Leadshine drives have a alarm output and I want to add this signal to my CPU's estop circuit. Could someone give advice how this should be done? I assume I cannot just put there outputs in series with estop button, I need somekind of relay circuit?
I attached caption of Leadshine manual where is said how this alarm output works. Also attached caption how CPU's estop works.

You may be able to add a relay or other sensor on the ALM+ and - open collector output, but it need s a bit more information as to the nature of the output?
If you can add a small relay to these then a contact on the relay could be placed in series with the E-Stop circuit.

Adding to the same thread about HBS86 drivers alarm pin.

HBS86 manual say that alm+ and alm- pins can sink or source 20mA at 24v, how much mA is it at 12v then? I am looking for a way to wire it in series with proximity switch, that runs on 12v 300mA, and then connect them both to ST-V2 (somehow sometimes found as mach3) breakout board limit/end switch pin.
So, when stepper miss his step, driver go’s to error mode and then breakout board stops other axis movement.
