Tool compensation
Tool data can be read and set using the variable numbers.
Variable number range
Type 1
Type 2
#10001 to #10000 + n
#2001 to #2000 + n
(Length dimension)
#11001 to #11000 + n
#2201 to #2200 + n
(Length wear)
#16001 to #16000 + n
#2401 to #2400 + n
(Radius dimension)
#17001 to #17000 + n
#2601 to #2600 + n
(Radius wear)
"n" in the table indicates the tool No.
The maximum value of "n" matches the number of tool offset sets.
Numbers in the #10000 order have the equivalent function to that in the #2000 order, however, the
maximum value of "n" for #2000 order is "200".
When the number of tool offset sets is larger than "200", use the variables of #10000 order.
The tool compensation data are configured as data with a decimal point in the same way as for
other variables. Consequently, programming as "#10001 = 1000;" results the setting "1000.000" in
the tool compensation data.
#101=1000;
#10001=#101;
#102=#10001;
#101=1000.0
#102=1000.0

(Note)
In this example, no consideration is given to the delay in the skip sensor signal.
#5003 is the Z axis start point position and #5063 is the Z axis skip coordinates, and
indicated is the position at which the skip signal is input while G31 is being executed.
