The function code is set as follows:
8.1.3 "Communication" setting operation command
Set parameter F0.01=2, communication can realize the start, stop and other related command control of
the inverter.
NVF2G-S can support RS485 communication, see the appendix for details of Modbus communication protocol.
8.2 Frequency command setting
There are three types of frequency command input, namely main frequency command, auxiliary frequency
command, and superposition of main and auxiliary frequency commands.
8.2.1 Selection of main frequency command source
Set parameter F0.02 to select the input of the main frequency command. There are 9 types of main
frequency commands of the inverter .

8.2.2 Operation panel to set main frequency (digital setting)
There are four situations when setting the main frequency with the operation panel and performing
frequency correction based on the UP and DOWN functions:
● The unit digit of F0.13 is 0 ( no memory after power failure) , that is, the set frequency value will return
to the set value of the digital setting (F0.05) after the inverter stops or is powered on again after power
failure .
● The unit digit of F0.13 is 1 ( power-off memory) , that is, when the inverter is powered on again after
power-off, the set frequency is the frequency setting value at the time of last power-off .
● The tens place of F0.13 is 1 (the stop frequency returns to the initial value), set the digital frequency of
F0.05 with the panel, and then use the up and down keys on the keyboard or terminals UP and DOWN
