When setting the station number, the following points should be taken into consideration:
1) The station number may be set between 1 and 64.
Fully note that if the station number is changed during operation, data communication cannot be made with the new
station number.
2) Setting method
z
Set the arrow (×) of the corresponding switch to the required numeral.
Example:
y
For station number 1: Set (×) of ×10 to "0" and (×) of ×1 to "1".
y
For station number 26: Set (×) ×10 to "2" and (×) ×1 to "6".
z
Set station numbers consecutively in a connection sequence.
(The station numbers may also be set independently of the connection sequence.)
z
Note that the same station number cannot be repeated.
(If the same station number is repeated, proper communication cannot be made.)

2) Allows input data to be read, output data to be written, and a CC-Link faulty station to be read, etc. (The FROM/TO
instruction is not needed when the automatic refresh function is used.)
Buffer memory is accessed by the FROM and TO instructions in the sequence program. For full information on the buffer
memory, refer to the CC-Link system master/local unit manual.
3) CC-Link start is dictated by the sequence program. After CC-Link is initiated, I/O refresh is continually executed
independently of (or in synchronization with) the sequence program execution.

PROGRAMMING EXAMPLES
6.11 Instructions
(1) Programming instructions
1) Since the buffer memory data of the master station is kept transferred (refreshed) to/from the inverters, the TO
instruction need not be executed every scan in response to data write or read requests.
The execution of the TO instruction every scan does not pose any problem.
2) If the FROM/TO instruction is executed frequently, data may not be written reliably.
When transferring data between the inverter and sequence program via the buffer memory, perform the handshake to
confirm that data has been written without error.
Correct
TO instruction
Write completion
Incorrect
TO instruction
Write completion
(2) Operating and handling instructions
1) During CC-Link operation, the inverter only accepts commands from the PLC and ignores any external operation
command and any operation command from the parameter unit.
2) If the same station number is set to different inverters, wrong data will be transferred and normal communication
cannot be made.
3) The inverter is brought to any of the alarm stops "E.OPT" if data communication stops, even instantaneously, due to a
PLC fault, an open CC-Link dedicated cable etc. during CC-Link operation.
4) If the PLC (master station) is reset during CC-Link operation or if the PLC is powered off, data communication stops
and the inverter is brought to any of the alarm stops "E.OPT".
To reset the PLC (master station), switch the operation mode to the external operation once, then reset the PLC.
45
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.
!
Check that the inverter starting program is running.
!
Check that the inverter is providing output.
