PROGRAMMING EXAMPLES

5)When the main power of any inverter is restored, that inverter is reset to return to the external operation mode. To resume the CC-Link operation, therefore, set the operation mode to the CC-Link operation using the PLC program. Note that setting "1" in Pr. 340 (link start mode) selects the CC-Link operation mode.

(3)Troubleshooting

1)Operation mode does not switch to CC-Link

!Check that the CC-Link units (FR-E5NC) and CC-Link dedicated cables are fitted properly. (Check for contact fault, open cable, etc.)

!Check that the station number setting switches are set to the correct positions. (Check that the station number matches the program, the station numbers are not repeated, and the station number is not outside the range.)

!Check that the inverter is in the external operation mode.

!Check that the operation mode switching program is running.

!Check that the operation mode switching program has been written correctly.

2)Inverter does not start in CC-Link operation mode

!Check that the inverter is in the CC-Link operation mode.

!Check that the inverter starting program has been written correctly.
