4.3. Basic functions
This clause shows the basic function of this CC-Link option using by CC-Link communication.
4.3.1. 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 control 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
Command mode selection
cmod :4
[Communication option input](Factory setting: 0)
Frequency setting mode selection
fmod :7[Communication option input](Factory setting: 2)
Torque command selection
f420 :7[Communication option input](Factory setting: 3)
*The frequency setting and command can be made CC-Link priority by RYnA and RYnB.
*"n" is depend on the station number.
4.3.2. Monitor
It is able to monitor the status of the inverter.
Set a 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.
・Refer to "Section 4.4.6. Description of monitor code" about the monitor code and unit.
4.3.3. 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 write data to RWw(n+3) if necessary) and
turn RYnF (instruction code execution request) on. The inverter performs processing
corresponding to the command code, return the response data, read out data and RXnF
(instruction code execution completion).
・Refer to "Section 4.4. Communication specification" about the command code, the unit
of the data, and the setting range.
