RS-485 Communication Features
7.2.5 Setting Virtual Multi-Function Input
Multi-function input can be controlled using a communication address (0h0385). Set codes
CM.70–77 to the functions to operate, and then set the BIT relevant to the function to 1 at 0h0322
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 CM.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 CM.70 to FX and set address 0h0322 to 0h0001.
The following are values and functions that are applied to address 0h0322:.
7.2.6 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 comunication 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. Parameters defined by communication can only be saved using
an LCD keypad.
