88 • Chapter 6 Programming Motion DMC-1700/1800
_PRx Returns current incremental distance specified for the ‘x’ axis
Example - Absolute Position Movement
PA 10000,20000 Specify absolute X,Y position
AC 1000000,1000000 Acceleration for X,Y
DC 1000000,1000000 Deceleration for X,Y
SP 50000,30000 Speeds for X,Y
BG XY Begin motion
Example - Multiple Move Sequence
Required Motion Profiles:
X-Axis 500 counts Position
10000 count/sec Speed
500000 counts/sec
2 Acceleration
Y-Axis 1000 counts Position
15000 count/sec Speed
500000 counts/sec
2 Acceleration
Z-Axis 100 counts Position
5000 counts/sec Speed
500000 counts/sec Acceleration
This example will specify a relative position movement on X, Y and Z axes. The movement on each axis will be
separated by 20 msec. Fig. 6.1 shows the velocity profiles for the X,Y and Z axis.
