Specifies movement from
point a to point b with an
absolute or incremental
programming in the figure
on the right.
X
P
is the X-axis (basic
axis) or its parallel axis,
Y
P
is the Y-axis (basic
axis) or its parallel axis,
and Z
P
is the Z-axis
(basic axis) or its parallel
axis.
Specify the distance
between points b and c
in the right-hand figure
with address J, J, K, or
C followed by a sign.
(When bit 4 (CCR) of
parameter No. 3405 is
set to 0, use I, J, or K.
When the bit is set to1,
use C.)
Movements are made from a to d
to c.
