(2) iS7 Inverter Operation Reference
PLC option can provide operation reference to an inverter.
▶ Common area of inverter
Referring to the parameters (exclusively for control) of inverter common area in the “App. 4-6, page 4,
Appendix,” the addresses of the common area of the inverter operation reference are as follows.
Common Area

▶ 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.
Code Function Name Set Value
DRV01 Cmd Frequency 11.52 Hz
DRV06 Cmd Source PLC
DRV07 Freq Ref Src Keypad-1
APO60 PLC Wr Data1 0382 Hex
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.
