Addressing by means of index and subindex

A parameter (Lenze code) is addressed according to the formula:

Index = 24575 - (Lenze code number)

Example
The parameter C00011 (motor reference speed) is to be addressed.
Calculation:

Index:
– Decimal: 24575 - 11 = 24564
– Hexadecimal: 0x5FFF - 0xB = 0x5FF4

Subindex: 0x00 (subindex 0 because the parameter has no subcodes)
