Incremental Motion
Incremental motion is commanded relative to the current position.
To move an incremental distance (a distance “relative” to the
current position), use a slash mark ( / ) following the axis.
NOTE:
The slash mark is only applicable in linear-interpolated
motion.
Example 1
In this example, the X axis moves an incremental distance of 20 units
from its current position. Then the Y axis moves a decremental
distance of 30 units from its current position.
X/20
Y/-30
Example 2
The X axis makes an incremental move, Y axis makes an absolute
move, and Z axis makes a decremental move. Written on the same
line, this is a coordinated move; all axes complete their moves at
the same time.
X/2 Y2 Z/-2
Comparing Absolute and Incremental Motion
Different types of motion can be used to achieve the same result.
The following examples show absolute and incremental motion, and
a combination of the two. All three examples end at the absolute
position of 400 units.
Example—Absolute Motion
The X axis is commanded to the following absolute positions:
X0
X100
X200
X300
X400
