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.
Setting address 0h03E0 to ‘0’ and then setting it again to ‘1’ via communication allows the
existing parameter settings to be saved. However, setting address 0h03E0 to ‘1’ and then
setting it to ‘0’ does not carry out the same function.
