15. COMPENSATION FUNCTION
B–62754EN/01
254
D When a G53 command is executed in tool–tip radius compensation
mode, the tool–tip radius compensation vector is automatically
canceled before positioning, that vector being automatically restored
by a subsequent move command. The format for restoring the tool–tip
radius compensation vector is the FS16 type when bit 2 (CCN) of
parameter No. 5003 is set to 0, or the FS15 type when the bit is set to
1.
D When a G28, G30, or G30.1 command is executed in tool–tip radius
compensation mode, the tool–tip radius compensation vector is
automatically canceled before automatic reference position return,
that vector being automatically restored by a subsequent move
command. The timing and format for canceling and restoring the
tool–tip radius compensation vector are the FS15 type when bit 2
(CCN) of parameter No. 5003 is set to 1, or the FS16 type when the
bit is set to 0.
When a G53 command is executed in tool–tip radius compensation mode,
a vector having a length equal to the offset is created, at the end of the
preceding block, perpendicular to the direction in which the tool moves.
When the tool moves to a specified position according to the G53
command, the offset vector is canceled. When the tool moves according
to the next command, the offset vector is automatically restored.
The format for restoring the tool–tip radius compensation vector is the
start–up type when bit 2 (CCN) of parameter No. 5003 is set to 0, or the
intersection vector type (FS15 type) when the bit is set to 1.
