CRC-16 Calculation Example
<Header and Trailer (Silent Interval)>
• Wait time between receiving the query from the master and the response by the Inverter.
• Be sure to provide 3.5 characters (24 bits) for wait time. If the length does not reach 3.5 characters,
the Inverter does not respond.
• The actual communication wait time is the total of the silent interval (3.5-character length) and
C078 (communication wait time) setting.
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.
