.....older post hopefully I can still get a lil help cuz they are pricey

I know there's not alot of info out there on these D.O.s as they comes "pre-configured" per job specs. I also have same issue on one now.
I have used the SSM and all parameters appear to still be correct
SSM is giving me fault code "5" which I do not know what it is?
I can confirm on SSM and operator both open and close limits/positioning is correct as well as "mm" positioning

1) "running in slow speed" is synchronization speed
2) put elev on cartop insp. On D.O.do "hard reset" hold down open and close buttons at same time, all 5 leds should flash on and off. After doors do learn run "ERR" led should be off.
3) my problem is I can not get doors to do learn run and get "ERR" led off, it stays lit

I do know what led up to this condition...doors continued to try and open with door restrictor hung up causing D.O.mtr to continually run slipping on belt for about 6 mins till retrictor was freed up

Last post about love joy coupling is only thing I haven't checked.

Any thoughts? Thxs
