7 Basic Functions
This interface allows the drive to be connected to a CC-Link network as a remote device, making it possible to operate, adjust settings, and monitor
the operation status of the drive using the PLC program. Both bit and word data cyclic transmission are available, and high speed communication up
to 10 Mbps is possible.
Below is a description of the basic CC-Link functions that can be performed by the PLC.
Note: Set parameters when operating the drive from a PLC. For instructions, see CC-Link Option Drive Parameters on page 16 .

Switching Between Command/Reference Sources
The Run command, Stop command, and the frequency reference can be entered directly from the operator or given from a separate control device.
To use a separate control device to issue the Run command and frequency reference, the drive needs to be set so that it accepts theses commands
from an external source.
■ Selecting an External Source
Follow the directions below set the drive up to accept commands from an external controller.
• Using Parameters to Select the Command/Reference Source
• Using the External Terminals to Switch the Command/Reference Source
• Using a PLC as the Command/Reference Source
■ Using Parameters to Select the Command/Reference Source
Selecting the Run Command Source
Set b1-02 (Run Command Selection) to 3 ("Option PCB").
Selecting the Source of the Frequency Reference
Set b1-01 (Frequency Reference Selection) to 3 (“Option PCB”).
■ Using the External Terminals to Switch the Command/Reference Source
Selecting the Run Command Source 2
Set b1-16 (Run Command Source 2) to 3 (“Option card”).
Selecting the Source of the Frequency Reference 2
Set b1-15 (Frequency Reference Source 2) to 3 (“Option card”).
Selecting the Run Command and Frequency Reference Source
By setting one of the multi-function input terminals S1 through S8 to supply auxiliary reference (H1-01 to H1-08 = 2), then the frequency reference
set to b1-15 and the run command source set to b1-16 will become enabled.
■ Using a PLC as the Command/Reference Source
Using Parameters to Switch Sources
Note: By setting H1-†† = 2, then parameters b1-15 and b1-16 will become enabled when that terminal is switched on.
• Selecting the Run Command Source
Send write data “3” for command code 2181H to the drive.
The setting for parameter b1-02 changes to “3”.
• Frequency Reference Source Selection
Send write data “3” for command code 2180H to the drive.
The setting for parameter b1-01 changes to “3”.
Using NetRef and NetCtrl
It is also possible to change the source of the frequency reference and the Run command using remote register RW
W2
command code 00FBH.
If the power is shut off, however, the drive will use the original setting for the command/reference source once the power is turned back again. This
method should therefore only be used when briefly switching between command/reference sources.
