Making Motion 83

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:

X100

X200

X300

X400
