Parameter: Page:
H: Integer Format 17-9
H: Word Format 17-10
Function
This parameter is used for mill and surface grinder controls only. It is used
for an H-word that programs a tool length offset number. The H-word is
used during tool length offset programming and any other time that data
for tool length is necessary. When programmed, the control uses the
H-word to call information from the tool geometry and tool wear tables for
tool length.
This parameter specifies the maximum number of digits that are permitted
to the left of the decimal point in the H-word format. The number of digits
to the right of the decimal point will always be zero since this parameter
has an integer format.
