Communication setting
(Underlined setting: default)
*1 When no parity setting is made, set “2 bits” for stop bit.
When a parity setting (even or odd) is made, set “1 bit” for stop bit.
When Connecting to the Built-in RS-485 Port on the Inverter:
Set communication parameters.
Be sure to match the settings to those made under [Communication Setting] of the editor.
(Underlined setting: default)
* The communication parameter (data length) is fixed to 8 bits.

H37 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.
