Modbus TCP
AC30 series Variable Speed Inverter
Supported Modbus Functions
Four Modbus functions are supported:
READ HOLDING REGISTERS (#3)
This function allows multiple Input registers to be read. Up to 125 registers may be read. As the Holding registers and Input registers map to the
same inverter parameters this will return the same values as the Read Input Registers function.
READ INPUT REGISTERS (#4)
This function allows multiple Holding registers to be read. Up to 125 registers may be read. As the Holding registers and Input registers map to
the same inverter parameters this will return the same values as the Read Holding Registers function.
WRITE SINGLE REGISTER (#6)
This function allows a single Holding register to be written to. Note that this function may only be used on registers that map to 1-byte or 2-byte
inverter parameters. An attempt to write to a register that maps to a 4-byte parameter will have no effect on the parameter.
WRITE MULTIPLE REGISTERS (#16)
This function allows a contiguous block of Holding registers to be written to. Up to 120 registers may be written. Note that when writing to
registers that map to 4-byte inverter parameters both registers must be written to. Writing to one-half of a 4-byte parameter will have no effect on
the parameter.
