Function
This parameter is used for the milling cycles of mill controls, the drilling
cycles of lathe controls and the grinding cycles of grinder controls.
A Q-word in a cycle block is used to program various information
depending on the cycle. Generally it is used to program either a shift
amount for cycles that use a spindle orient or to program an infeed amount
for cycles that reach total cutting depth in steps.
This parameter specifies the maximum number of digits that are permitted
to the left and to the right of the decimal point in the Q-word format when
programming in inch or metric modes.
