Application and exemplary program
1) 1) Set up the inverter parameters as shown below. In the APO60(PLC Wr Data1), enter the
“0382Hex” which is the address (page 4, “App. 4-6, Appendix) of the common area of the inverter
operation reference.

2) APO60 (PLC Wr Data1) corresponds with D4454 which is the special register of the PLC option by 1:1
relation. Since the APO60 (PLC Wr Data1) is registered with the common area address (0382Hex) of the
inverter operation reference, a specific value inputted in the D4454 in ladder program, the value will be
the operation reference of the inverter.
