Hello,

I have an issue with the inputs on the add I/O card in the mill I am interfacing a 4th axis too. The DEC4 input X19.5 (decel limit sw for the 4th axis) causes all the inputs assigned to the M20 plug to come on and latch. This is the only input used on the 50pin plug and also the only one wired into the plug. Even with all the other plugs disconnected every input for the M20 plug comes on and latches until the machine is turned off and back on. I have tried a different input card and it still does the same. Just wondering if anyone has ever stumbled across this issue? As this switch is wired normally closed it never sees the decel signal due to all the inputs latching on.
Cheers
