RS-485 Protocol Selection (y20)
Determines the RS-485 port protocol, and must be set to a value of “0” (Modbus RTU).
3.2 Inverter Control-Related Settings
The following function codes relate to whether or not the inverter is to be controlled (command word
and/or frequency command) from the network, or whether the inverter will be locally-controlled, and only
monitored and/or configured via the network.
Communications Link Function (Mode Selection) (H30)
If the inverter is to be controlled from the network (both command word and frequency command), then
set the value of H30 to 8. Otherwise, set the value of H30 as appropriate for the chosen command and
frequency command input sources.
Bus Link Function (Mode Selection) (y98)
If the inverter is to be controlled from the network, then set the value of y98 to 0 (follow H30 data). A
setting of 0 for y98 may also be appropriate even if H30 is configured for an alternate (local) control
scheme.
