I don´t know what you mean with B 7 or B 5 - don´t you see my image of the settings ?
I'm not using the PC to program it. The manual has B as Brake and option B: 5in the manual is Very Hard/1,3 sec. and B: 7 doesn't have a brake value, but it shows the 2,3 sec., so it seems that one can actually get more options with the PC programming.
