Preface
Compatibility Quick Check
Use the following comparison table to confirm that there are compatible
PowerFlex 755TM bus supplies available to migrate from your existing
PowerFlex 700AFE bus supply. If the existing PowerFlex 700AFE installation
configuration does not have any of these exceptions, proceed to use the
guidelines in this document.
If the existing PowerFlex 700AFE bus supply has any of the above
configuration exceptions, contact an Authorized Rockwell Automation
Distributor specialist, Solution Partner, Recognized System Integrator, or
Rockwell Automation account manager to discuss engineered solutions for
custom migrations.

Table 1 - Comparison Quick Check Considerations
Consideration If you have these existing PowerFlex
700AFE Configuration Exceptions
Then follow these recommendations
for the PowerFlex 755TM Bus Supply
migration
Maximum DC bus
current and power
output
More than 2 x frame 13 AFE bus supplies in
parallel.
When this migration guide was published
there were no compatible units available.
Future product enhancements may expand
the range of migration solutions.
Mixed Frame Sizes Any combination of frame 10 and frame 13
AFE converters in parallel.
Mixed frame parallel migration solutions
are not covered in this migration guide. A
custom migration solution may be
required.
Custom Packaging IP00 open type units that are installed in non-
standard enclosures.
Open type IP00 PowerFlex 755TM Bus
Supplies are available. IP00 conversions are
not covered in this migration guide. A
custom migration solution may be
required.
Parallel non-
regenerative bus
supply
Any system with an AFE in parallel with a
non-regenerative converter (diode or SCR
rectifier). The most common configuration
was an AFE in parallel with PowerFlex SCR
converter(s).
The PowerFlex 755TM Bus Supply cannot be
combined in parallel with any other bus
supply converters.
Integration with
common DC bus
drive system lineup
DC bus bars, control bus bars integrated
between the AFE and common bus inverter
drive enclosures.
This configuration can be migrated to
PowerFlex 755TM bus supply, however, this
solution is not covered in this migration
guide.
The IP21/IP54 enclosed PowerFlex 755TM
bus supply converter bus bar configuration
is not mechanically compatible with any
existing PowerFlex 700AFE configurations
and may require a custom migration
solution with transition cell enclosure(s).
Communication
Protocol
ControlNet Fiber
BACnetIP
HVAC Modbus RTU
CANopen
Interbus
LonWorks
Modbus/TCP
Remote I/O
RS485 DF1
These communication protocols are not
supported by the PowerFlex 755T product.
A custom migration solution and/or an
external communication protocol converter
may be required.
