4.4.3.8 PROFIBUS-DP communications card (OPC-PDP2)
This communications card may not apply to the inverter depending upon the inverter ROM
version. Consult your Fuji Electric representative.
The PROFIBUS-DP communications card is used to connect the FRENIC-AQUA series to a
PROFIBUS-DP master via PROFIBUS. Mounting the communications card on the FRENIC-AQUA
enables the user to control the FRENIC-AQUA as a slave unit by configuring and monitoring run and
frequency commands and accessing inverter's function codes from the PROFIBUS master.
The communications card has the following features:
- PROFIBUS version : DP-V0 compliant
- Transmission speed : 9,600 bps to 12 Mbps
- Applicable profile : PROFIDrive V2
- Able to read and write all function codes supported in the FRENIC-AQUA
Ports available for the communications card
This communications card can be connected to the A-port only, out of three option connection ports
(A-, B-, and C-ports) provided on the FRENIC-AQUA.
Note: Once the inverter is equipped with this communications card, no more communications card
(e.g., DeviceNet and SX-bus communications cards) is allowed on the inverter. Mounting more than
one card on the inverter causes the Er4 trip that cannot be reset until those cards are removed except a
single card.

Addressing
- By on-board node address switches (rotary
switches) (0 to 99)
or
- By inverter’s function code o31 (data = 0 to 125)
Setting both node
address switches SW1
and SW2 to "0" enables
the o31 setting.
