H30 Communication link function (Mode selection)
Related function codes: y98 bus link function (mode selection)
Using the RS-485 communications link, built-in CAN communications link 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. It is possible to sets the source that specifies the
frequency and run commands with H30 and y98. H30 and y98 set the sources that specify RS-485
communications and fieldbus respectively.
When the built-in CAN communications link is enabled with y33 = 1, the fieldbus in the figure below is replaced with
the built-in CAN communications link.
