    Actually, with this particular motor, the standard shaft is taper. Here is the decoding for this one. It does not apply to all FANUC alpha servo motors.

    A06B-0127-Bxyy

    X : 0 (taper shaft -- standard)
    X : 1 (tapers shaft with brake)
    X : 5 (straight shaft)
    X : 6 (straight shaft with brake)

    YY: 75 (pulse coder alpha A64)
    YY: 77 (pulse coder alpha I64)
    YY: 88 (pulse coder alpha A 1000)

    Note: There is often a suffix after the the -Bxyy which can call for straight shaft with key, IP67, special bearings, etc. Too many to list.
