- Operations specific to individual tool offset memory types
The offset to be changed varies with what tool offset memory (A, B, or
C) is used, as listed below.

Offset to be changed
A The tool length compensation and cutter compensation are
processed in the same way. If the currently valid H code and D
code have the same value, the offset at the same offset
number is changed.
B The tool length compensation and cutter compensation are
processed in the same way. If the currently valid H code and D
code have the same value, the offset at the same offset
number is changed.
Either tool geometry compensation or wear compensation is
changed according to the setting of parameter ASG (bit 4 of
parameter No. 0014).
C The tool compensation and cutter compensation at the offset
numbers corresponding to the currently valid H code and D
code, respectively, are changed separately.
Either tool geometry compensation or wear compensation is
changed according to the setting of parameter ASG (bit 4 of
parameter No. 0014).
- Presetting the relative position indicator
Setting parameter APL (bit 7 of parameter No. 2214) to 1 can preset the
relative position indicator (counter) to 0 automatically when active
offset change mode is selected. In this case, performing manual feed
until the relative position indicator (counter) becomes 0 can restore the
previous value of the offset.
- Tool life management
If a tool management option is available, compensation is carried out
using the T code (tool group number), M06 (tool change command),
and H99/D99 (or H code/D code set in parameter No. 7443 or 7444). In
this case, a change is made to the compensation corresponding to the
compensation number made valid by these commands. If there is no
currently valid compensation number (for example, just after a reset is
executed of when no T code or tool change command has been
executed since cycle start), manual feed-caused axis movement does
not affect the compensation.
- Tool offset by tool number
If a tool offset by tool number option is available, and setting parameter
NOT (bit 5 of parameter No. 0011) = 0, compensation is carried out
using the T code (tool number) and M06 (tool change command) rather
than the H or D code. In this case, a change is made to the
compensation corresponding to the currently valid tool number. If
there is no currently valid tool number (for example, just after a reset is
executed of when no T code or tool change command has been
executed since cycle start), manual feed-caused axis movement does
not affect the compensation.
