Set it when servo motor with brakes.
Bit 2: Set 3, brake interlock signal ―/BK‖ is output from
CN1-29, CN1-30 to control 24V relay used for brake.

selection 1
0211
Set it when servo motor with brakes.
To avoid of CN1-29 and CN1-30 being used for other
function and leading to brake ineffective, 3 is not
allowed to appear in the 4 digits.
