Functions
Message configuration: Response
<Total Communication Time>
•The time between receiving query and the response by the Inverter is the total of the silent interval
(3.5-character length) and C078 (communication wait time) setting.
•When sending another query to the Inverter after receiving the response from the Inverter, be sure
to provide the silent interval length (3.5-character length or more) at the minimum.
<Normal Response>
•If the query is the loopback function code (08h), the Inverter sends back a response of the same
content as the query.
•If the query contains a function code of writing into the holding register or coil (05h, 06h, 0Fh, 10h),
the Inverter sends back the query as it is in response.
•If the query contains a function code of reading the holding register or coil (01h, 03h), the Inverter
makes the slave address and function code the same as the query and attaches the read data to
the query.
<Abnormal Response>
•If an error (aside from a communication error) is found in the query content, the Inverter returns an
exception response without performing any operation.
•To determine the cause of an error, check the function code of the response. The function code of
the exception response is the value of the query function code with 80h added.
•Check the details of the error with the exception code.
