Chapter 1 Selection Considerations
AC Input Dimensional Cross
Reference
Table 2 5 through Table 28 compare approximate dimensions of PowerFlex
700S and PowerFlex 755TL/TR drives. Shaded rows in the table indicate an
acceptable cross-reference unless noted otherwise. Outline dimensional
drawings are shown in Appendix A on page 121
.
If the existing PowerFlex 700S has regeneration that is provided by a separate
Regen Unit or braking chopper/resistor, these devices would be assembled in a
separate enclosure that would consume floor space as well. The equivalent
PowerFlex 755TL/TR drive would replace both the PowerFlex 700S drive and
the associated Regen Unit or braking chopper/resistor. The overall dimensions
of the PowerFlex 700S and regenerative device may be the same or larger than
the equivalent PowerFlex 755TL/TR migration solution.
Because it is impossible to predict the combinations of hardware that could be
used in the existing PowerFlex 700S drive configuration the tables below only
consider migration solutions based on published catalog ratings for the
PowerFlex 700S drives.
IMPORTANT There are no valid AC input dimensional cross-references from PowerFlex
700S AC input 6 pulse drives to PowerFlex 755TL or PowerFlex 755TR drives.
PowerFlex 755TL/TR drives all contain an integrated active front end
converter that requires more panel space than the 6-pulse converters that
are used in the PowerFlex 700S.
IMPORTANT The PowerFlex 700S frame 9 drive is usually mounted within an enclosure,
however, it can be wall-mounted per the catalog numbers shown. The
equivalent PowerFlex 755TL/TR drive is supplied as a floor standing
enclosure. Consider the mounting and enclosure types that are used for your
PowerFlex 700S frame 9 migration solution to ensure the PowerFlex 755TL/
TR enclosed drive can be installed in the available space.
