Restrictions
(1) If tool radius compensation amount has already been set, the compensation amount is not be
changed even if the parameter "8117" is changed.
(2) Make sure not to change the parameter #8117 during the compensation.
When the parameter is changed using parameter input by program function, the program error
(P241) will occur.
(3) If the parameter #8117 is set to ON with the parameter "#1037 cmdtyp" set to “2”, the tool radius
wear data is also regarded as the diameter compensation amount, thus, it will be converted to
the radius value and compensation will be performed.
(4) Diameter designation of tool radius compensation amount can be used for the tool life
management data.
(5) There is no effect by #8117 on the tool radius measurement function.
