10.2.3. Modbus Parameter Access
All User Adjustable parameters (Groups 1 to 5) are accessible by Modbus, except those that would directly affect the Modbus
communications, e.g.
 P5-01 Drive Fieldbus Address – see also P5-16 Drive Modbus Address.
 P5-03 Modbus RTU Baud Rate.
 P5-04 Modbus RTU Data Format.
All parameter values can be read from the drive and written to, depending on the operating mode of the drive – some parameters
cannot be changed whilst the drive is enabled for example.
When accessing a drive parameter via Modbus, the Register number for the parameter is the same as the parameter number,
e.g. Parameter P1-01 = Modbus Register 101.
Modbus RTU supports sixteen bit integer values, hence where a decimal point is used in the drive parameter, the register value will be
multiplied by a factor of ten,
e.g. Read Value of P1-01 = 500, therefore this is 50.0Hz.
For further details on communicating with Optidrive using Modbus RTU, please refer to your local Invertek Sales Partner.
