*Not available for Master Only axes.
† Only available in iCODE firmware V2.3 and earlier.
An axis must always be specified (in word 0), even for system variables
that are not axis-specific (like Last_Keypress). For analog input values
(only available in IMC-S/20x-R and IMC/S21x-R model motion
controllers), the axis specifies the corresponding analog input (specify
axis 0 to read analog input 0, axis 1 for analog input 1, etc.). In addition,
since only one system variable value can be transferred in each BTR,
always put 01 for the number of items in the low byte of word 2 in the
BTW data file for the transfer.
