Chapter 6 Programming Motion

Overview

The DMC-1700/1800 provides several modes of motion, including independent positioning and jogging, coordinated motion, electronic cam motion, and electronic gearing. Each one of these modes is discussed in the following sections.

The DMC-1710 or DMC-1810 are single axis controllers and use X-axis motion only. Likewise, the DMC-1720 or DMC-1820 use X and Y, the DMC-1730 or DMC-1830 use X,Y, and Z, and the DMC-1740 or DMC-1840 use X,Y,Z, and W. The DMC-1750 or DMC-1850 use A,B,C,D, and E. The DMC-1760 or DMC-1860 use A,B,C,D,E, and F. The DMC-1770 or DMC-1870 use A,B,C,D,E,F, and G. The DMC-1780 and DMC-1880 use the axes A,B,C,D,E,F,G, and H.

The example applications described below will help guide you to the appropriate mode of motion.
