H30 Communications Link Function (Mode selection)
Using the RS-485 communications link (standard/option) or fieldbus (option) allows you to
issue frequency commands and run commands from a computer or PLC at a remote location,
as well as monitor the inverter running information and the function code data.
H30 and y98 specify the sources of those commands--"inverter itself" or "computers or PLCs
via the RS-485 communications link or fieldbus." H30 is for the RS-485 communications
link; y98 for the fieldbus.

Run commands contain digital input via terminals [X1] to [X7] in addition to FWD
and REV via terminals [FWD] and [REV]. No concurrent run command input from
the inverter unit (FWD/REV) and the RS-485 communications link (digital input
via [X1] to [X7]) is possible.
y98 (Bus Link Function, Mode selection)
Sources except RS-485 communications link and fieldbus
Frequency command source: Specified by F01/C30, or
multistep frequency command
Run command source: Via the keypad or digital input
terminals selected by F02
Via the standard RJ-45 port used for connecting a keypad
Via the terminals DX+, DX- and SD on the control PCB
Via fieldbus (option) using FA protocol such as DeviceNet
or PROFIBUS DP
