Depends on the machine. The factory limits on my supermax signal the controller AND also opens a contactor for the drives. You can override the input to the control (now EMC) all you like but it still doesn't bring the drives back up. You have to mechanically move off the limits (luckily they left little knobs for that.) I thought about changing the factory wiring to allow the EMC override to work but I'll never be ~3000mi away...
So, so you know if its a software only limit or does it affect other hardware interlocks too? I was able to get the overrides to function on another machine so I think they work (that was 2.4.x). You could always go into you hal and comment out the limit sw input (or negate it.)
