Chapter 2 About the Drive
DPI Communication Ports For Frame 3 drives, the Communication Interface board contains three DIN
connectors that are used as DPI communication ports (
Figure 12 ). These ports
provide communication between the LiquiFlo 2.0 drive and other DPI devices
(for example, an OIM or a personal computer running the VS Utilities software).
The three connectors (DPI ports 3, 4, and 5) are equivalent. This manual
assumes that peripherals are always plugged into DPI port 3.

For Frame 4 drives, there is only one DPI port, accessible via the OIM connector
on the front panel of the power module (see
Figure 13 ). An internal cable
connects this connector to the DIN connector on the control board. A device
plugged directly into this connector uses DPI port 3. If there is a requirement
that multiple DPI peripheral devices be connected, a DPI port expander box can
be used, but no device should be plugged into the DPI Port 2 connector because
the rectifier connects to the inverter using that port.
