I don't have it in front of me, but the AX5000s ship with a dummy card 
that bridges a few pins together (perhaps hard-wiring what the pair of 
safety relays on the AX5801 do). I suspect the drive won't run without 
it.

As this is not strictly on-topic for Etherlab, I'll send you off-list a 
picture of the dummy card tomorrow. I think I have one sitting on my 
desk at work. It would be trivial to replicate and bridge out the 
connector pins if you can't get hold of a dummy card easily.

You're on the right track with P-0-2000, but I think your best bet is to 
stick with the AX5801, especially as this is the `dumb' non-TwinSAFE 
card, so you just need to wire it up as per the manual.

For the AX5801, I believe the correct value for P-0-2000 is 3.

Sometimes the easiest way to figure this stuff out is to run the 
hardware from TwinCAT---it's a free download after all, no need to call 
up the local sales rep and feign interest like some other unnamed 
automation manufacturers.
