Related function codes: y94 bus function (Operation command source selection)
y98 bus function (Operation selection)
Using the RS-485 communications link, built-in CAN communications link or fieldbus (option) allows you to issue
frequency settings and run operation commands (run stop/general-purpose digital input) from a computer or PLC
at a remote location, as well as monitor the inverter running information and the function code data. It is possible to
sets the source that specifies the frequency settings and run operation commands with H30, y94, and y98. H30
selects RS-485 communication, and y94 and y98 select the fieldbus setting procedure.
