Parameters which can be displayed when the plug-in option (FR-A8NC) is mounted.The setting is reflected after inverter reset or at the next power-on.

"L.ERR" LED flickers if the setting is changed. If the inverter is reset, the setting is reflected and the LED turns off.Refer to the Instruction Manual (Detailed) of the inverter for the parameter details.

The setting is available only for the FR-A800 series.

The settings of Pr.544="24, 28, or 128" and Pr.810="2" can be set only when the inverter supports this function. (Refer to page 73.)

4.2Operation mode setting

4.2.1Operation mode switching and communication startup mode (Pr.79, Pr.340)

Operation mode switching conditions

Check the following before switching the operation mode.

• The inverter is at a stop;

• Both the STF and STR signals are off; and

• The Pr.79 Operation mode selection setting is correct. (Check the setting on the operation panel of the inverter.)

Operation mode selection at power ON and at restoration from instantaneous power failure

The operation mode at power ON and at restoration from instantaneous power failure can be selected.

Set a value other than "0" in Pr.340 Communication startup mode selection to select the network operation mode. After started in network operation mode, parameter write from the network is enabled.

(Refer to page 85 for a program example for parameter write.)

NOTE

•Change of the Pr.340 setting is valid when powering on or resetting the inverter.

•Pr.340 can be changed with the operation panel independently of the operation mode.

•Ensure that the communication setting of the inverter is completed before setting Pr.340 "0".

•Refer to the Instruction Manual (Detailed) of the inverter for details of Pr.79, Pr.340.
