Coupled Power Modules
Frame 2 combined Converter/Inverter Power Modules are configured only
as coupled power modules. Coupling the Converter and Inverter is achieved
by using two factory-installed cables: a control synchronization cable and
an inverter-to-converter DPI communication cable. The two cables are
described in the next two subsections.
Control Synchronization Cable
To enable synchronization between the Inverter control board and the
Converter control board, a factory-installed control synchronization cable
connects each board. No user connection is required. However, the
connection method is different for PowerFlex 700L drives with 700 Vector
Control than for 700S Phase II Control. The 700 Vector Control
synchronization cable connection is shown in
. The 700S Phase
II Control synchronization cable connection is shown in
