DN - The DN configuration supports DC powered motor drives in the
Main Area only, but no Load Area. In the DN configuration, the J8
circuits, normally reserved for Load area functionality, may be used as
additional Main Area circuits. Example part number:
EF-785- DN xx-xxx-x.

PURCHASING A UNIT FOR DEVELOPMENT
For the purposes of machine design and development, Teknic
recommends that you initially order the
AA configuration. This leaves
your design options open (the AA configuration can do the work of any
of the other four power configurations). Once your machine design is
stable, order only the options you need.

The eF-785 offers two available EMI filtering options, two-stage (D) and
four-stage (Q) .

ILTERING
The basic level of EMI filtering offered for the eF-785 is two-stage ( D ual)
filtering indicated by the letter D in the position shown above. The 2-
stage option is standard in configurations where only DC powered motor
drives are present in the machine (i.e. power control configurations DD
or DN). This (lesser) magnitude of filtering is usually sufficient for
machines in which there are no AC powered motor drives present.

ILTERING
Quad or four-stage filtering is specified by the letter Q. Four-stage
filtering comes standard on all eF-785s configured for AC powered motor
drives (i.e. power configurations AA, AD, and AN). With this level of
filtering, your machine can meet EN 50081-2 and EN 50082-2 for
emissions and susceptibility without individual line filters for each servo
drive (typically a notable cost savings).
