Code Description
3 Hold Input The inverter calculates the average input value for
10 seconds before the loss of the speed command
and uses it as the speed reference.
4 Hold Output The inverter calculates the average output value for
10 seconds before the loss of the speed command
and uses it as the speed reference.
5 Lost Preset The inverter operates at the frequency set at Pr. 14
(Lost Preset F).
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.
Note
The following are values and functions that are applied to address 0h0322:.

0h0001 Forward operation (Fx)
0h0003 Reverse operation (Rx)
0h0000 Stop
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
