DRV10987: Hello, i'm trying to configrate drv10987 controller with GUI109xx software

Part Number: DRV10987

Hello,

i have some problem with drv10987 GUI and controller. first one i can't write fraction number motor phase resistance . İ have seen many of demonstrate on you tube that they can write fraction  resistance with GUI but when i try to write it always round to integer (for example i write 0.35 it round to 0  or i write 0.6 it round to 1).  The same problem have with DRV10983 but  i change motor resistance with arduino and write to controller eprom. You can see the image in blow.

 By the way motor  resistance: 0.35 and back EMF : 58 and it works properly with drv10983 and i configure paramters close with drv10987  and try to run motor GUI always gives the same " overcurrent" error even it doesn't try spin motor. i mean doesn't drawn current from source.  i define motor phase resistance = 1 ohm and change BEMF for many times but result doesn't change.

1 ) Could you plase let me know why i can't write fraction number with GUI 

,2 ) Why GUI always give " overcurrent" error.
