Value assignments to axial machine data
In principle axial machine data have an array index of the AXIS data type. In the case of
value assignments to an axial item of machine data using SET or REP, this array index is
ignored or not processed.
Example: Value assignment to machine data MD36200 $MA_AX_VELO_LIMIT
$MA_AX_VELO_LIMIT[1,AX1]=SET(1.1, 2.2, 3.3)

Is equivalent to:
$MA_AX_VELO_LIMIT[1,AX1] = 1.1
$MA_AX_VELO_LIMIT[2,AX1] = 2.2
$MA_AX_VELO_LIMIT[3,AX1] = 3.3
