life management cancel number specified in parameter7440 to
a group number. For example, to set tool group 1 when the
tool life management cancel number is 100, specify T101;

begins counting the life of the new tools selected with the T
H99 ; H code registered in the tool life management data of the tool

be enabled by an H code other than 99.
H00 ; Cancels tool length offset
