Preface
Compatibility Quick Check
Use the following comparison table to determine if there are compatible
PowerFlex 755T products available to migrate your existing PowerFlex 700S. If
the existing PowerFlex 700S installation configuration does not have any of
these exceptions, proceed to use the guidelines in this migration guide.
Table 1 - Comparison Quick Check Considerations
Consideration If You Have These Existing
PowerFlex 700S Configuration
Exceptions
Then Follow These Recommendations
for the PowerFlex 755T Migration
Minimum AC output
current and power
Frames 1…6 No compatible units available at initial
product release. Consider PowerFlex 755
products for these ratings.
AC Line Voltage 200…240V AC, 3 PH, AC input No compatible units available at initial
product release.
Braking Chopper
IGBT
Frame 9 with optional internal brake chopper
IGBT
Internal brake chopper IGBT are not
available for PowerFlex 755T frames
8…12. Specify a regenerative
PowerFlex 755TR drive or external third-
party brake chopper module.
Integration with
common AC or DC
bus drive system
lineup
• Bulletin 2362 with PowerFlex 700S
packaged in 2100 MCC enclosures with AC
or DC power and control bus.
• Custom packaged common AC or DC bus
PowerFlex 700S drives.
This configuration can be migrated to
PowerFlex 755TM, however, this solution is
not covered in this migration guide.
The IP21/IP54 enclosed PowerFlex 755TM
common bus inverter busbar configuration
is not mechanically compatible with any
existing PowerFlex 700S common DC bus
configurations and may require a custom
migration solution with transition cell
enclosure(s).
Resolver feedback
device
Optional resolver feedback module Requires third-party option module
(AMCI RD750).
SynchLink™ SynchLink fiber-optic communication
protocol that is used for drive to drive to
controller high-speed dedicated
communication links
No compatible communications link
available.
DriveLogix™ and
Compact I/O™
Use of the DriveLogix controller or Compact
I/O expansion capability
No compatible feature available at initial
product release. Migration Solutions
on
page 111 of this document outlines
possible migration solutions that integrate
a PowerFlex 755T with a Logix controller.
Custom Packaging IP00 open type units that are installed in non-
standard enclosures.
This may require a custom migration
solution. Custom migration solutions are
not covered in this migration guide.
Communication
Protocol
ControlNet Fiber Optic
BACnet/IP
HVAC Modbus RTU
CANopen
Interbus
LonWorks
Modbus/TCP
Remote I/O
RS485 DF1
The PowerFlex 755T product does not
support these communication protocols. A
custom migration solution and/or an
external communication protocol converter
may be required.
PowerFlex 700S
Phase I
Phase I Control This migration guide only covers
PowerFlex 700S Phase II migrations.
