Title: How to add a second input to an E-STOP?
Post by: Rimbaldo on May 30, 2020, 10:37:38 AM

Hi!

My Gecko G-540 BOB is wired to an E-Stop Input on Mach3.

But I bought a new Brushless Motor to my lathe's spindle that in it's controller it also has an output pin as a Fault Alarm.

I'd like to also wire this "Fault" output of the Motor's controller to another input of my BOB and also trigger an E-Stop.

How do I do it, If my E-Stop input is already used by the Gecko's own E-stop?

Regards, Rodrigo

If you have a spare input (pins 1-4) then one of them could be used.
You need to first check the voltage levels from your 'spindle fault signal' to make sure it is suitable for connection to the G540 then the Gecko's input pin could be configured in a similar way to a limit switch and when triggered will operate Estop.
