Title: Strategy for servo drive faults with Galil?
Post by: Instance on December 08, 2011, 07:13:10 PM

I have a Galil motion controller (DMC-4143) connected to Pacific Scientific servo drives for 3-axis CNC.  Each one of the servo drives (there's 4 of them, its a slaved gantry) has a fault output.  I want the system to stop anytime there's a fault on any of the four servo drives.  I would prefer not to use discrete logic to combine these outputs.  Is the best strategy to connect each of them to a seperate general purpose input on the Galil and somehow map those to e-stop?  Any guidance appreciated.

There is a General Abort input that can be configured with the CN command, if you want to save on inputs, you could parallel four open collector 2n7000 or a ULN2803 to combine into one output.
This input aborts motion and stops the program automatically .
