4.2. Basic functions

This clause shows the basic function of this CC-Link option using by CC-Link
communication.
4.2.1. Run and frequency operation command
The PLC program can operate the inverter to run, stop, set the operation frequency and
change the parameters.
If the PLC controls these operations, select the command mode and the frequency setting
mode. (Change the setting of the torque command selection if necessary.)
The parameter setting of the inverter
4.2.2. Monitor
It is able to monitor the status of the inverter.
Set the monitor code to RWwn and turn RYnC on. The data is stored in the buffer
memory of the PLC.
"n" is depend on the station number.

4.2.3. Writing and reading the parameter
The PLC can read, write the inverter parameters and reset the inverter.
Set the command code to RWw(n+2) (set the data to RWw(n+3) if necessary) and turn
RYnF (instruction code execution request) on. The inverter performs processing
corresponding to the command code, and return the response data, the read out data
and RXnF (instruction code execution completion).
Refer to the "CC-Link Option Function Manual E6581477" for the command code, the
