For example, if you want to send an Fx command by controlling a virtual multi-function input
command addresses with Int485, the Fx function is performed if 0h0001 is input in 0h0385
after COM-70 (Vir
tual DI 1) is set to “FX” . Before you configure the virtual multi-function inputs,
set the DRV-06 (CMD source) depending on the command source.
Virtual multi-function operates independently from the analog multi-function inputs and
cannot be set redundantly. Virtual multi-function input can be monitored using COM-86 (Virt Dl
Status).
11.8 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. Howe ver, setting address 0h03E0 to “1” and then
setting it to “0” does not carry out the same function.
Before reading the parameters utilizing CNF-46 (Parameter Read), make sure to save the
parameter changes (Parameter Save) to read the parameter values reflecting the changes in
the communication module parameters.
