Functions
ModBus-RTU Method
Follow the procedures below in regards to communication between the external controller and the
Inverter.
(1) : Frame to be sent from the external control device to the Inverter (Query)
(2) : Frame to be returned from the Inverter to the external controller (Response)
(3) : Unless the Inverter completes reception of a query from the host within the time set in C077
after the Inverter completes a response (response transmission), the Inverter becomes ready
to receive the first data again. In this case, the Inverter sends no response.
Also, the Inverter's operation conforms to the setting of communication error selection C076.
For details, refer to the following table.
The receiving timeout monitor starts after the first transmission/reception is performed after
power-on or reset. Receiving timeout is inactive until reception or transmission is performed.
Response from the Inverter (Frame 2) is output as return after the Inverter receives the query
(Frame 1), not output independently.
