Cannot run brushless hub motor in closed-loop

Hi all,
I am not having any success with running this (see attached datasheet) brushless hub motor in closed loop with our GBL26120S. I can run it in open loop but only with trapezoidal switching mode and not in Sinusoidal. Not sure why this is also.

Please note this controller was purchased as a dual channel, but i have updated the firmware to a single channel and followed the proper wiring requirements.I am using a 48V 50AH LifePO4 lithium battery to run the motor. 

After running the motor smoothly in open loop mode, i selected closed loop speed and sinusoidal switching. I then tried to run the Motor/Sensor Setup. The motor turns a very small amount and then i receive a Motor/Sensor fault. I notice that the Motor Amps peak at the Reference Seek Power (50A) that i have set. I don't understand why this even needs to be this high to run this setup feature.

When i try running the Motor Characterisation feature, i set the Reference Seek Power (2) and i get the following exception.

boardName = GBL2XXX :GBL26120S

$ SHORT!
EXCEPTION: FAULT FLAG APPEARED!

Could someone please help me to resolve this issue. I really need to get this motor working in closed-loop.

Thanks

Bumping this thread, I am having the same issue where it turns a very small amount and back. Mine succeeds, but then will not drive at all in manual modes (i.e. the run tab). I am using the SBL2360T.

Thanks for jumping onto this topic. I am curious to understand if this forum is even active any longer? Would really like to hear from a moderator if any are logging in these days. 

I had similar problems with my SBL2360T running firmware 2.1. It worked in open loop, but closed loop would always report a short. I saw that they had removed the "Short Circuit" setting in firmware 2.1 that used to be available and in the firmware documentation I saw comments like "Fixed false positive short". I assume they switched it to some sort of automatic mode and that the code still has scenarios of false positive shorts. I downgraded my firmware to 2.01 and everything works fine.
