1-14 Overview
Drive Interface Module
The 1394-DIM (Drive Interface Module) provides four channels of 
analog output, four drive enable outputs, and four drive fault inputs. 
The 1394-DIM allows the 1394x-SJTxx-C, -T, or -L system module to 
be used to control any external drive with a ±10V velocity torque 
reference command and quadrature encoder output. Each 1394-DIM 
can support up to four drives. However, the maximum number of axes 
(1394-DIM controlled drives plus 1394x-AMxx axis modules) cannot 
exceed four per 1394x-SJTxx-C or -T system module and one per 
1394C-SJTxx-L system module. The 1394-DIM is not compatible 
with the 1394x-SJTxx-A system module.

DC Link Module
The 1394-DCLM (DC Link Module) provides additional load 
leveling and energy storage (capacitance) for 1394 systems. This 
allows additional regenerative energy to be stored during the machine 
cycle, increasing system capacity, lowering cycle time, and avoiding 
resistive heat loss. The module can be used alone or two modules can 
be used to interconnect two 1394 systems using the DC Link cable.
