Hi, I had this fun with mach3 as well, it is more likely to be noise causing a false trigger of the e stop line into the pc, rather than an e stop signal from the drive unit itself.

One option is to put a capacitor between the common and e stop pin going into the pc (about 0.1uf I think), the other is to put a dwell in the Mach3 config screen (I think its called interval debounce?), try setting a figure higher than the default of 0, I have a figure of 3000 to get rid of false external e stops with a cap across the e stop input pins too.
I hope that helps you, good luck.

Cheers, Andrew.
