Product Overview

The FDPI-02 Diagnostic and Panel Interface is used to branch the RS-485 panel bus and chain a control panel or PC tool to multiple drives.

This interface device provides a straight-through connection between the control unit and the F-type option module.

It is compatible with the ZCU-xx and BCU-xx control units. The interface unit is installed in the option slot of the control unit.

A small F-type option module can then be mounted on top of the Interface Unit.

The Interface Unit has one RJ-11 and two RJ-45 connectors.The RJ-11 connector is used to connect to the Control Unit.

The RJ-45 connector supports a daisy-chained bus for connection to a PC or control panel (simultaneous control panel and PC communication is not allowed).

Bus termination is required to prevent signal reflection at the end of the bus cable. The interface unit has a panel/PC cable bus termination switch.

The termination switch must be in the terminated position www.abb-drive.com if the device is the first or last device on the bus.

If the control panel is connected to one end of the bus, it will terminate the bus, only the other end must be terminated via termination switch S1.

The following figure shows the layout of the interface unit.
