XHC WHB04b-6 strange behavior

Hello all,
I have changed my pedant from XHC WHB04-L to XHC WHB04b-6. 
After adjusting the Hal file, I found some strange problems.
1. the display shows percentage 5%, 10%. even in step mode.
2. i use the command xhc-whb04b-6 -H (without option B ) to load the driver, but the step size 5mm and 10mm is active. 
3. when I start the spindle, the speed is always 101 rpm higher.
Does anyone have any idea what is wrong?

Regards
Karlram
