5.4.Basic functions
This clause shows the basic function of this
5.4.1. 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.
The parameter setting of the inverter Command mode selection
cmod : 4[Communication option] (Factory setting: 1) Frequency setting mode selection
fmod : 7[Communication option] (Factory setting: 0)
*The frequency setting and command can be made
5.4.2.Monitor
It is able to monitor the status of the inverter. Set a monitor code to RWw n and turn RYnC on. The data is stored in the buffer memory of the PLC. * "n" is depend on the station number.
The monitor value is updated while RynC has been turned on.
Refer to 5.5.11 for detail.
5.4.3. 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 5.5.8 for detail.
