Communication Setting
Editor
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 under [Communication Setting] of the editor.
(Underlined setting: default)
*1 Select “Modbus RTU” for the communication protocol on the inverter when connecting with the V9.
*2 When “0” is specified for y99 (support link function), command from function code H30 is valid for the frequency setting and operation
command.
*3 The communication parameter (data length) is fixed to 8 bits.

y07 Stop bit
For Modbus RTU communication, the stop bit setting is automatically
made according to the parity bit setting.
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.
