All user configurable parameters are accessible as Holding Registers, and can be Read from or Written to using the appropriate Modbus
command. The Register number for each parameter P-04 to P-60 is defined as 128 + Parameter number, e.g. for parameter P-15, the register
number is 128 + 15 = 143. Internal scaling is used on some parameters, for further details please contact your Invertek Drives Sales Partner.
