Letter Format Parameters
Chapter 17
17-6
Notes
This parameter is a global parameter; it applies to all axes and processes.
This parameter is not used for decoding the E-word when E is being used
to program the reciprocation feedrate, or when E is used in a G38 block.
In these cases, the current F-word format is used for decoding the E-word.
The F-word format parameters are covered on these pages:

Function
This parameter specifies the maximum number of digits that are permitted
to the left and to the right of the decimal point in the F-word format. This
parameter specifies the format of an F-word that is used to program a
linear feedrate, and specifies the format of the reciprocation feedrate
(E-word) for grinder application types.
