    RS-485 bus cable should be terminated with a 120 ohm resistor

    on both ends to prevent signal reflection. When no device on the

    network is transmitting, noise can be falsely interpreted as

    communication data. To avoid this, termination can be included

    with a fail-safe circuit (pull-up and pull-down resistors). The circuit

    forces the bus into a known idle state when no device is

    transmitting.

    The FMBA-01 Modbus Adapter module

    The FMBA-01 Modbus Adapter module is an optional device for

    ABB drives which enables the connection of the drive to a RS-485

    network. The FMBA-01 provides galvanic isolation between the

    drive and RS-485 network and converts serial communication

    signals of the drive to RS-485 signal levels.

    The FMBA-01 has a built-in bus termination with fail-safe circuitry.

    The termination can be activated with a jumper.

    The adapter module is mounted into an option slot on the motor

    control board of the drive. See the drive documentation for module

    placement options.Compatibility

    The FMBA-01 Modbus Adapter module is compatible with all

    stations that comply with RS-485.
