Functions
<Slave Address>
• Pre-set numbers ranging from 1 to 32 in each Inverter (slave). (Only the Inverter having the same
slave address as the query takes in the query.)
• Broadcasting can be performed by setting the slave address to "0".
• Data call or loopback cannot be performed while broadcasting.
<Data>
• Sends the function command.
• The 3G3MX Series corresponds with the following data formats used in the ModBus.
<Function Code>
• Specifies a function for the Inverter to perform.
• Below are the function codes available to the 3G3MX Series.
Function code
<Error Check>
• CRC (Cyclic Redundancy Check) is used for the Modbus-RTU error check.
• The CRC code is 16-bit data generated for the block of random length data in the 8-bit unit.
• To prepare the CRC code, use a generation polynomial of CRC-16 (X16 + X15 + X2 + 1).
