*1.
Refer to the following table for the number of sent/received characters.
*2.
Indicates the number of sent/received characters required to write 1 parameter.
The IVBWR instruction executes parameter writing by the number of times of communication
.
*3.
The inverter gives no response because the inverter is being reset.
The PLC waits for 2.2 s until reset of the inverter is completed, and then completes execution of the
inverter communication instruction.
*4.
Refer to the following table for the data check time in inverters.
Make sure to refer to the manual of the inverter used, and confirm the data check time for the
communication command used.
The IVWR, IVRD and IVBWR instructions automatically change expansion parameters and the 2nd
parameter.
The data check time for the last (2nd or 3rd) sending/receiving in the IVWR and IVRD instructions and
the data check time for the last sending/receiving of each parameter writing in the IVBWR instruction
correspond to parameter reading/writing (< 30 ms).
The data check time for sending and receiving (expansion parameter change and 2nd parameter
change) other than the above correspond to various monitors (< 12 ms).
