Instructions
 Operating and handling instructions
• The inverter only accepts the commands from the programmable controller during operation using the CC-Link IE Field
Network Basic.
The run command from external and parameter unit is ignored.
• If multiple inverters have the same station number, the communication cannot be performed properly.
• The inverter protective function (E.EHR) is activated if data communication stops for more than the time set in Pr.1432
Ethernet communication check time interval due to a fault such as a programmable controller fault or a break in the
Ethernet cable, during operation through the CC-Link IE Field Network Basic.
• If the programmable controller (master station) is reset during operation through the CC-Link IE Field Network Basic or
if the programmable controller is powered off, data communication stops and the inverter protective function (E.EHR) is
activated.
To reset the programmable controller (master station), switch the operation mode to the external operation once, then
reset the programmable controller.
• When Pr.340 = "0 (initial value)", any inverter whose main power is restored is reset to return to the external operation
mode. To resume the network operation, therefore, set the operation mode to the network operation using the
programmable controller program.
Set a value other than "0" in Pr.340 to start in the network operation mode after inverter reset. (For the details of Pr.340,
refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.)
