IACDRIVE I5000 Series Operation Manual page 115

Different respond delay can be set through drive's parameters to adapt to different needs. For
RTU mode, the respond delay should be no less than 3.5 bytes interval, and for ASCII mode,
no less than 1ms.
The main function of Modbus is to read and write parameters. The Modbus protocol
supports the following commands:
0x03 Read inverter's function parameter and status parameters
0x06 Write single function parameter or command parameter to inverter
All drive's function parameters, control and status parameters are mapped to Modbus R/W
data address.
The data addresses of each function parameters please refer the sixth column of chapter 9.
The data address of control and status parameters please refer to the following table.
