Application and exemplary program
1) Set up the inverter parameters as follows. In the APO60 (PLC Wr Data1), enter 0386Hex which is the
common area address of the inverter digital output (page 4, “App. 4-6, Appendix).

0386 Hex
2) APO60 (PLC Wr Data1) corresponds with the D4454 which is the special register of PLC option by 1:1
relation. Since the APO60 (PLC Wr Data1) is currently registered with the common area address
(0386Hex) of the virtual multi-function output of the inverter, if a specific value is entered in the D4454 by
the ladder program, the value will be the digital output of the inverter.
3) In the sample program below, if D4454 is written with h0003, 30A-30C of Relay1 and AXA-AXC of
Relay2 are short-circuited. And then, if D4454 is written with h0000, the 30A-30C and AXA-AXC of
Relay2 are opened.
