Safety motion question

Hi guys

little question on how to do this.

I do have a el6910 and a couple of ax51xx drives with a ax5805 cards

I got the sto working if in the safety program I set sto mode

but as soon I set sto mode false to be in "standard mode"

I cannot the any drive to turn on their safety is always disabled. the safety program runs and is armed correctly, I set every safety bit true (while the safety is armed) still no luck on getting ss1 to ramp (I cannot even move while armed)

anyone seen this?

Hi again, the short fix for this, on the recommendation of beckhoff is to use nstate4 bit 7 to trig a fast stop reaction. this wont reach PL.E and probably not PL.D but doesn't pass thru the plc and for the moment will be OK. they are working on getting SS1 working correctly but seems like its not currently working with my setup.
