Part Numbers
The DMC controller board comes in two sizes, 1-4 axis models (labeled A-D) and 5-8 axis models (labeled E-H).
The number of axis is designated by x in the part number DMC-41x3. In addition, Axis A-D and Axis E-H have their
own set of axis-specific options that can be ordered. For example, Axis A-D can have a different set of feedback
options as Axis E-H even though they reside on the same DMC-41x3 board. The DMC-41x3 can also be ordered
with optional internal amplifiers, labeled as AMP or SDM. These amplifiers are “sandwiched” to the back of the
DMC-41x3 board. The abstract internal layout of a DMC-41x3 with optional AMP/SDM is shown for 1-4 axis in
Figure 1.1.
The 5-8 axis models have room for an additional bank of internal amplifiers as shown in Figure 1.2.
It is important to note that if the DMC-41x3 is ordered without optional AMP/SDM options that it can come in
either a card or box form factor, ordered as -CARD or -BOXn respectively; where n denotes 4 (for 1-4 axis models)
or 8 (for 5-8 axis models). If the DMC-41x3 is ordered with an optional AMP/SDM then it must be ordered with a
-BOXn. Table 1.1 below shows the different form factors and the appropriate part numbers to order them.
