RS-485 Communication Features
7.3 LS INV 485/Modbus-RTU Communication
7.3.1 Setting Virtual Multi-function Input
Multi-function input can be controlled using a communication address (0h0385). Set codes COM-
70–77 to the functions to operate, and then set the BIT relevant to the function to 1 at 0h0385 to
operate it. Virtual multi-function operates independently from IN-65–71 analog multi-function
inputs and cannot be set redundantly. Virtual multi-function input can be monitored using COM-
86 (Virt Dl Status). Before you configure the virtual multi-function inputs, set the DRV code
according to the command source.

Example:
When sending an Fx command by controlling virtual multi-function input in the
common area via Int485, set COM-70 to ‘FX’ and set address 0h0385 to ‘0h0001’.
7.3.2 Saving Parameters Defined by Communication
If you turn off the inverter after setting the common area parameters or keypad parameters via
communication and operate the inverter, the changes are lost and the values changed via
communication revert to the previous setting values when you turn on the inverter.
Set CNF-48 to ‘1 (Yes)’ to allow all the changes over communication to be saved, so that the
inverter retains all the existing values even after the power has been turned off.
