Canopen Communications Card (Opc-Cop) - Fuji Electric FRENIC-HVAC User Manual

4.4.3.10

CANopen communications card (OPC-COP)

The CANopen communications card is used to connect the FRENIC-HVAC series to a CANopen
master unit (e.g., PC and PLC) via a CANopen network. Mounting the communications card on the
FRENIC-HVAC allows the user to control the FRENIC-HVAC as a slave unit by configuring run and
frequency commands and accessing inverter's function codes from the CANopen master unit.
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-HVAC.
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.
