[17] CANopen communications card (OPC-G1-COP)
The CANopen communications card is used to connect the FRENIC-MEGA series to a CANopen master
unit (e.g., PC and PLC) via a CANopen network. Mounting the communications card on the
FRENIC-MEGA allows the user to control the FRENIC-MEGA as a slave unit by configuring run and
frequency commands and accessing inverter's all function codes from the CANopen master unit.
Applicable ports
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-MEGA.
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.
Applicable ROM version
This communications card is applicable to inverters with a ROM version G1S11000 or later.
