Figure 7 graphs the change in position for the X and Y axes. The Y axis is
dashed. The overall slope of the position curve for the Y axis is steeper,
reflecting its higher

JOG VEL

value (

JOG VEL X25 Y50)

.

Comparing the first curve after

t

0

for the axes show that a higher acceleration

value presents as a more gradual curve (

JOG ACC X1000 Y500)

.

Figure 7 X and Y Position Motion Profiles

Example 2

The

JOG VEL

value is changed while a single axis is in motion (on the

fly (OTF)).

JOG ACC X20
JOG DEC X25
JOG VEL X10
JOG INC X10
DWL 1.0
JOG VEL X5

At one second (

t

0

+ 1.0 sec.), the axis is commanded to decrease

speed to the new velocity. See Figure 8 for the velocity profile.
Motion ends at

t

1
