FANUC Series 16/18/160/180-Model C for Lathe Operator Manual

OPERATION
B–62754EN/01
11. SETTING AND DISPLAYING DATA
675
In some cases, tool wear compensation or tool geometry compensation
values cannot be input because of the settings in bits 0 (WOF) and 1
(GOF) of parameter 3290. The input of tool compensation values from
the MDI can be inhibited for a specified range of offset numbers. The first
offset number for which the input of a value is inhibited is set in parameter
No. 3294. The number of offset numbers, starting from the specified first
number, for which the input of a value is inhibited is set in parameter No.
3295.
Consecutive input values are set as follows:
1) When values are input for offset numbers, starting from one for which
input is not inhibited to one for which input is inhibited, a warning is
issued and values are set only for those offset numbers for which input
is not inhibited.
2) When values are input for offset numbers, starting from one for which
input is inhibited to one for which input is not inhibited, a warning is
issued and no values are set.
The radius and TIP are not displayed if the tool tip radius compensation
option is not displayed.
When offset values have been changed during automatic operation, bit 4
(LGT) and bit 6 (LWM) of parameter 5002 can be used for specifying
whether new offset values become valid in the next move command or in
the next T code command.
