The cause of F30103 " Crowbar Thyristor Activated "

I would like to know if there is anything other than the DC link overvoltage that can activate the crowbar thyristor. The other thing I would like to know is how to interpret r0949. I get that its an integer and that you should turn it to hex or binary. When I turn it to hex the number given such as r0949[18] = 51. I go to r0947[18] = 30103. I do not find any where that when I turn 51 to hex that the number 33 has any significance. Is this a drive object number or something? Another case is in the message buffer in scout I see F30103 " Crowbar thyristor activated " (hex B) once again the number 11 has no significance as far as I know. I have searched for some documentation on this subject and cant find anything in detail. My issue isn't that the crowbar thyristor activated. I know the reason for this. I am trying to figure out the all the possible causes for the crowbar thyristor to activate. For future reference because we have had instances in the past where we didn't know the root cause. Any input would be appreciated. Thanks
