Found these parameters:

143= +X Limit
144= +Y Limit
145= +Z Limit
146= +4 Limit
433= +5 Limit

147= -X Limit
148= -Y Limit
149= -Z Limit
150= -4 Limit
434= -5 Limit


145 was at 2000 so I changed it to 99999 and it didn't affect the startup after that. Still get the 434 alarm when holding PRP. Good idea though.
