The D-word integer and word letter format parameters are covered in the
following sections:
Parameter: Page:
D: Integer Format 17-3
D: Word Format 17-4
Function
This parameter specifies the maximum number of digits that are permitted
to the left of the decimal point in the D-word integer format. Since this
parameter has an integer format, the number of digits to the right of the
decimal point will always be zero.
Use this parameter when programming a D-word that corresponds to a tool
diameter (or radius) offset number. Use D-words during cutter
compensation and any other time that data for tool diameter (or radius) is
necessary. When programmed, the control uses the D-word to call
information from the tool geometry and tool wear tables for tool diameter
(or radius).
