Communication setting
(Underlined setting: default)
*1 When no parity setting is made, “2 bits” is set for stop bit.
When a parity setting (even or odd) is made, “1 bit” is set for stop bit.
Inverter
Set communication parameters.
Be sure to match the settings to those made on the [Communication Setting] tab window of the editor. (Underlined setting:
default)
*1 Select “Modbud RTU” for the communication protocol on the inverter when connecting with the S8.
*2 When “0” is specified for y99 (support link function), command from function code H30 is valid for the frequency setting and operation
command.
