Three–dimensional coordinate conversion does not affect the degree of
manual intervention or manual handle interrupt.
Three–dimensional coordinate conversion does not affect positioning in
the machine coordinate system (e.g. specified with G28, G30, or G53).
Specify linear rapid traverse when three–dimensional coordinate
conversion is executed. (Set the LRP bit, bit 1 of parameter No.1401, to
1.)
In a block with G68 or G69, other G codes must not be specified. G68
must be specified with I, J, and K.
Programmable mirror image can be specified, but external mirror image
(mirror image by the mirror image signal or setting) cannot be specified.
Three–dimensional coordinate conversion is carried out after the
programmable mirror image function is executed.
To display the absolute position when three–dimensional coordinate
conversion is executed, set bits 4 to 7 of parameter DRL, DRC, DAL, and
DAC No.3104 to 0.
Canned cycles G41, G42, or G51.1 must be nested between G68 and G69.
