Write in Coil [05h]:
This function writes data in a single coil. Coil status changes are as follows:
Data
Change data (high order)
Change date (low order)
An example follows (note that to command the inverter, set A002=03):
• Sending a RUN command to an inverter having slave address "10"
• This example writes in coil number "1."

3 Coil start number (high
order)
4 Coil start number (low
order) *2
5 Change data (high
order)
6 Change data (low order)
7 CRC-16 (high order)
8 CRC-16 (low order)
Note 1: Broadcasting is disabled.
Note 2: The starting coil number is one
less than the number of the coil to
be read first.
When the Write in Coil command cannot be executed normally, refer to the exception response.
Write in Holding Register [06h]:
This function writes data in a specified holding register. An example follows below.
• Write "50Hz" as the first Multi-speed 0 (A020) in an inverter having slave address "5."
• This example uses change data "50 (0032h)" to set "50Hz" as the data resolution of the
register "1203h" holding the base frequency setting (A003) is 1 Hz.
